A standard trap bar (also called a hex bar) weighs 55 lbs (25 kg). That is heavier than a typical 45 lb (20 kg) Olympic barbell because the hexagonal frame requires more steel than a straight bar. Trap bar weights range from 45 lbs (20 kg) to 65 lbs (29 kg) depending on the model, and weight capacities range from 500 lbs to 1,500 lbs.
Knowing the exact weight of your trap bar matters more than most lifters realize. If you are tracking progressive overload or comparing your trap bar deadlift numbers to your conventional deadlift, even a 10 lb discrepancy in bar weight throws off your programming. Research by Swinton et al. (2011) found that lifters can typically pull 5 to 10% more weight on a trap bar compared to a straight bar, so accurate load tracking is essential for honest performance comparison.
Below, I'll break down the factors that affect trap bar weight, compare six popular models side by side, and help you choose the right bar for your training goals.

Factors Affecting the Weight of a Trap Bar
Three main factors determine how much a hex bar weighs: material, size, and design.
Material
Trap bars are built from steel, and the gauge and grade of that steel affect the final weight. Heavier-duty bars use thicker steel tubing, which adds weight but also increases the bar's load capacity and long-term durability. Budget bars often use thinner steel to keep the weight (and price) lower, but they sacrifice maximum load capacity in the process.
Size and Sleeve Length
Longer trap bars weigh more because they require more material. The length also determines sleeve length, which controls how many plates you can load. A bar with 16-inch loadable sleeves can fit significantly more bumper plates than one with 10-inch sleeves. If you plan to load 500+ lbs, sleeve length matters as much as the bar's rated capacity.
Design: Closed Hex vs. Open Trap Bar
Traditional trap bars form a fully enclosed hexagonal frame. You step into the hex from above and are surrounded by the bar on all sides. These are sometimes called “closed” trap bars.
Open trap bars have a gap in the rear of the frame, allowing the lifter to walk into and out of the bar without stepping over it. This open design enables movements like lunges, split squats, and farmer carries that a closed hex bar cannot accommodate. Open trap bars (like the REP Open Trap Bar or the Titan Rickshaw) tend to weigh slightly more because they need additional bracing to compensate for the missing rear crossbar.
Some open trap bars also include a built-in deadlift jack, which raises the sleeves off the ground for easier plate loading. That jack adds weight but saves time between sets.
Trap Bar Weight Comparison: 6 Popular Models
The table below compares six popular trap bars by weight, capacity, approximate price, and key features. Notice the pattern: heavier bars generally handle more weight. That's one reason weight ranges matter when you're choosing gym equipment.
| Brand | Weight (lbs / kg) | Weight Capacity | Price Range | Key Features |
|---|---|---|---|---|
| REP Fitness Trap Bar | 55 lbs / 25 kg | 500 lbs | $250 to $300 | Traditional hex shape with high and low handle options |
| CAP Barbell Trap Bar | 45 lbs / 20 kg | 750 lbs | $100 to $150 | Budget hex bar with high handle grip and above-average capacity for its price |
| Rogue TB-2 Trap Bar | 60 lbs / 27 kg | 1,000 lbs | $350 to $400 | Heavy-duty hex bar built for serious loading, popular in commercial gyms |
| Titan Fitness Rickshaw Trap Bar | 50 lbs / 23 kg | 600 lbs | $150 to $200 | Open rectangular design for deadlifts, farmer carries, and bent-over rows |
| Elite FTS Hex Combo Bar | 50 lbs / 23 kg | 600 lbs | $250 to $300 | Traditional hex shape with higher-than-average capacity for its weight class |
| Kabuki HD Trap Bar | 65 lbs / 29 kg | 1,500 lbs | $700 to $750 | Adjustable design with built-in jack for fast plate loading, premium build quality |
The standard hex bar weight is 55 lbs (25 kg). This is heavier than a standard Olympic barbell (45 lbs / 20 kg) because the trap bar's hexagonal frame uses more steel than a straight bar. Weight capacities range from 500 lbs on budget models to 1,500 lbs on premium bars like the Kabuki HD.
Lightest Trap Bar: CAP Barbell (45 lbs / 20 kg)
At 45 lbs, the CAP Barbell is the lightest trap bar on this list and the most affordable. Despite its lighter weight, it handles up to 750 lbs, which makes it a strong value pick for home gyms. If you are a beginner or intermediate lifter who does not plan to exceed 700 lbs on your trap bar deadlift, this is a solid budget option.
Heaviest Trap Bar: Kabuki HD (65 lbs / 29 kg)
The Kabuki HD is the heaviest bar on this list at 65 lbs and has the highest weight capacity at 1,500 lbs. Its built-in jack lets you tilt the bar to load and unload plates without a separate deadlift jack. This is a premium bar for serious lifters and commercial gym owners who need maximum durability and capacity.
Hex Bar vs. Trap Bar: Is There a Difference?
No. “Hex bar” and “trap bar” refer to the same piece of equipment. The name “hex bar” comes from the hexagonal shape. The name “trap bar” comes from its original use for trap (trapezius) shrugs. Al Gerard, a competitive powerlifter, invented the trap bar in the mid-1980s as a way to keep deadlifting heavy while managing lower back pain. Most modern trap bars are hexagonal, but some (like the Titan Rickshaw) use an open rectangular design.
How to Find the Weight of Your Gym's Trap Bar
If you train at a commercial gym and need to know how much the trap bar weighs, try these approaches:
Check the end cap or sleeve. Many manufacturers stamp or engrave the bar weight on the end of one of the sleeves or on the frame near the handle. Look for a number followed by “lbs” or “kg.”
Look up the brand and model. Most trap bars have a brand name stamped or stickered somewhere on the frame. Search that brand's website for the exact model to find the listed weight.
Weigh it yourself. Step on a bathroom scale while holding the bar, then subtract your body weight. This gives you an accurate reading regardless of manufacturer specs.
Ask the gym staff. The front desk or a trainer can usually look up the equipment spec sheet, especially at larger chain gyms.
Do not assume your trap bar weighs 45 lbs just because a standard barbell does. Many commercial gym hex bars weigh 55 to 60 lbs, and that 10 to 15 lb difference adds up when you are tracking your deadlift progress.
Why Trap Bar Weight Matters for Your Programming
Accurate bar weight tracking affects three areas of your training.
Progressive Overload
If you think your trap bar weighs 45 lbs but it actually weighs 60 lbs, every set you have ever logged is 15 lbs heavier than you recorded. That means your actual strength is higher than your training log reflects, and your planned weight jumps may be smaller than you think. Getting the bar weight right lets you program honest, incremental increases.
Comparing Trap Bar to Straight Bar Numbers
Many lifters train both the trap bar deadlift and the conventional deadlift. Research shows that most people can pull 5 to 10% more on a trap bar using low handles compared to a straight bar. If you are using high handles, the advantage is even larger because of the reduced range of motion. Knowing both bar weights lets you compare the two lifts accurately.
Meet Prep and Competition Context
Trap bars are not used in powerlifting competitions, but many powerlifters use them as a training tool. If you are using trap bar deadlifts as an accessory or variation during your training cycle, knowing the exact bar weight helps you calibrate how your trap bar numbers translate to your competition deadlift strength.
How to Choose the Right Trap Bar
Choosing the right trap bar comes down to three factors: your current and projected strength level, your preferred handle type, and the exercises you plan to perform.
Match the Bar to Your Strength Level
Most lifters in their 20s or 30s can deadlift between 2 and 2.5 times their body weight with consistent training. For practical purposes, that means untrained lifters typically pull around 200 lbs, intermediate lifters work in the 300 to 400 lb range, and only advanced lifters regularly exceed 500 lbs.
A standard 55 lb trap bar with a 500 lb capacity will serve most lifters well. If your deadlift is approaching 500 lbs or you want room to grow without buying a second bar, step up to a 600 or 750 lb capacity model. Only competitive strength athletes or very strong lifters will need the 1,000 or 1,500 lb capacity bars.
High Handles vs. Low Handles
Most quality trap bars offer both high and low handle positions. The handle choice significantly changes the training stimulus.
High handles reduce the range of motion by a few inches, which lets you start the lift from a more upright position. This reduces stress on the lower back and makes the movement more quad-dominant. High handles are a great option for beginners learning the hip hinge, lifters managing back pain, or athletes focused on power development (since you can move heavier loads at higher velocities).
Low handles sit at the same height as a standard barbell on the floor, giving you a full range of motion that more closely mimics a conventional deadlift. Low handles are more demanding on balance and posterior chain strength. They are a better choice for experienced lifters who want the trap bar's neutral grip advantage without shortening the pull.
I recommend choosing a trap bar with both handle options so you can switch based on your training phase. Use high handles for volume blocks or when prioritizing speed and power. Use low handles when you want maximum carryover to your competition deadlift.
What Exercises Will You Perform?
A standard closed hex bar works well for deadlifts, shrugs, and Romanian deadlifts. If you also want to do farmer carries, lunges, or bent-over rows, you need an open trap bar that lets you walk in and out of the frame.
The Titan Rickshaw trap bar is a popular open design built for exactly this purpose. Its rectangular, open-back frame gives you room to walk, lunge, and move laterally while carrying the load.
Regardless of design, the trap bar's core advantage is the same: it positions the load in line with your center of gravity, which promotes better mechanics and reduces shear force on the lumbar spine compared to a straight bar.

Trap Bar vs. Barbell: Key Differences
If you are deciding between a trap bar and a standard barbell for your home gym, or wondering whether to add trap bar work to your program, here is how the two compare.
Bar weight: A standard Olympic barbell weighs 45 lbs (20 kg). A standard trap bar weighs 55 lbs (25 kg), with a range of 45 to 65 lbs depending on the model.
Grip: Barbells require a pronated (overhand) or mixed grip for deadlifts. Trap bars use a neutral (palms facing in) grip, which is easier on the shoulders and eliminates the bicep tear risk associated with a mixed grip. The neutral grip also reduces grip as a limiting factor, allowing you to train your legs and back harder before your hands give out.
Muscle emphasis: The conventional barbell deadlift places more demand on the hamstrings and spinal erectors because the bar sits in front of your center of gravity. The trap bar deadlift shifts some of that demand onto the quads because the load is centered around your body, allowing a more upright torso position.
Load capacity: Most lifters can pull 5 to 10% more weight with a trap bar (using low handles) compared to a straight bar. Using high handles increases that advantage further due to the reduced range of motion.
Versatility: A straight barbell works for bench press, overhead press, rows, squats, and deadlifts. A trap bar is more specialized but excels at deadlifts, shrugs, farmer carries (open design), and power training. If you can only own one bar, a barbell is more versatile. If you already have a barbell, adding a trap bar gives you a powerful deadlift variation with lower injury risk.

Frequently Asked Questions
How much does a trap bar weigh in kg?
A standard trap bar weighs approximately 25 kg (55 lbs). Lighter models weigh around 20 kg (45 lbs), and the heaviest commercial trap bars reach 29 kg (65 lbs). Always check the manufacturer's spec sheet or weigh the bar yourself for an exact number.
Is a trap bar heavier than a regular barbell?
Usually, yes. A standard Olympic barbell weighs 45 lbs (20 kg), while a standard trap bar weighs 55 lbs (25 kg). The trap bar is heavier because its hexagonal frame uses more steel than a straight bar. Some budget trap bars also weigh 45 lbs, so the weights can overlap at the low end.
Do you count the trap bar weight when calculating your deadlift?
Yes. The bar weight is always included in your total lift. If your trap bar weighs 55 lbs and you load two 45 lb plates on each side, your total deadlift weight is 235 lbs (55 + 90 + 90). Failing to account for bar weight leads to inaccurate training logs.
How much more can you deadlift with a trap bar compared to a straight bar?
Research suggests most lifters can pull approximately 5 to 10% more weight with a trap bar using the low handles. High handles increase the advantage further because of the shorter range of motion. The difference comes from the trap bar positioning the load closer to your center of gravity, which reduces the demand on your lower back and allows your quads to contribute more force.
How do I find out how much the trap bar at my gym weighs?
Check the end cap or sleeve for a stamped weight marking. If there is none, look up the brand and model online. You can also weigh it by stepping on a scale while holding the bar and subtracting your body weight. Asking the gym staff is another quick option.
What is the difference between an open trap bar and a closed trap bar?
A closed trap bar forms a complete hexagonal frame that you step into from above. An open trap bar has a gap in the rear, letting you walk into and out of the frame. Open designs enable more exercises (lunges, farmer carries, split squats) but tend to weigh slightly more because they need extra bracing.
Can you use a trap bar for exercises other than deadlifts?
Yes. Common trap bar exercises include shrugs, Romanian deadlifts, farmer carries (open design required), bent-over rows, overhead presses, and jump squats. The trap bar's neutral grip and centered load make it versatile for many pulling and carrying movements.
Is a trap bar worth it for a home gym?
If you already own a standard barbell, a trap bar is one of the best specialty bars you can add. It gives you a lower-back-friendly deadlift option, a tool for power training, and the ability to do heavy farmer carries in a small space. If you can only afford one bar, a standard barbell is more versatile, but a trap bar is a strong second purchase.
Final Thoughts
The standard trap bar weighs 55 lbs (25 kg), but hex bar weights range from 45 to 65 lbs depending on the model, design, and weight capacity. The lightest option on this list (the CAP Barbell at 45 lbs) handles 750 lbs and costs under $150. The heaviest (the Kabuki HD at 65 lbs) supports 1,500 lbs and includes a built-in deadlift jack.
For most lifters, a standard 55 lb trap bar with a 500 lb capacity is the right starting point. If your deadlift is approaching 500 lbs or you want a bar that will last through years of strength gains, invest in a 600 to 1,000 lb capacity model. Look for dual high/low handles so you can adjust the training stimulus based on your goals.
The trap bar is one of the most underrated tools in strength training. It lets you deadlift heavy with less lower back stress, train power output at higher velocities, and build serious leg and back strength with a movement that is easier to learn than a conventional deadlift.
