You’ve finally accepted that a straight barbell deadlift is beating up your lower back. Or maybe you just want a more joint-friendly pull that still lets you move serious weight. Either way, you’ve landed on the open trap bar — and now you’re staring at two popular options wondering which one deserves a spot in your home gym. The open trap bar decision matters more than most people think, because the wrong pick means awkward racking, wasted space, or a bar that doesn’t hold up once the plates start stacking.
Quick Answer
If you need a durable, versatile open trap bar built for heavy home gym use, the Bells of Steel Open Trap Bar wins overall. It offers a beefier frame, dual handle heights, and a higher weight capacity that serious lifters will appreciate. The CAP Olympic Open Trap Bar is a solid budget-friendly alternative for lifters who want basic hex bar functionality without spending as much. Both are open-ended designs that make plate loading and racking far easier than closed-frame trap bars.
TL;DR
The Bells of Steel is the better bar for lifters who plan to go heavy and want long-term durability. The CAP is a perfectly functional entry point if you’re on a tighter budget and don’t need to load 500+ pounds regularly.

Key Takeaways
- Open-ended designs on both bars let you walk into a rack and load plates from the side — a huge advantage over closed hex bars in tight home gyms.
- Bells of Steel offers dual-height handles, a higher weight capacity, and a more robust build for serious progressive overload.
- CAP comes in at a lower price point and covers the basics well for recreational lifters and beginners.
- Handle knurling, sleeve length, and overall bar weight differ meaningfully between the two — these affect your grip and how much plate you can load.
- For deadlifts, shrugs, farmer carries, and rows, the open trap bar is one of the most versatile specialty bars you can own.
Overview: What Is an Open Trap Bar?
A trap bar (also called a hex bar) is a specialty barbell you stand inside of to deadlift. Instead of the bar sitting in front of your shins, the load is centered around your body. This shifts stress away from your lower back and lets your quads do more work — which is why the American Council on Exercise (ACE) often recommends trap bar deadlifts as a safer alternative for general populations.
An open trap bar takes that concept further by removing the front crossbar. That open-ended frame means you can walk forward into a squat rack, load plates from the side without tilting the bar, and perform movements like farmer carries without the closed frame limiting your stride. For a home gym where space and convenience matter, the open design is a practical upgrade.
Both the Bells of Steel and CAP versions use this open-ended layout. The differences come down to construction quality, handle options, weight capacity, and price.

Bells of Steel Open Trap Bar — Full Breakdown
The Bells of Steel Open Trap Bar is built for people who treat their home gym like a long-term investment. The frame feels noticeably thicker in hand, and the aggressive knurling on both handle heights gives you a locked-in grip even on heavy sets. Dual handles let you switch between a higher, more upright pulling position (great for beginners or those with mobility issues) and a lower handle that mimics a conventional deadlift depth.
Where this bar really earns its keep is weight capacity. With 750+ pounds of rated capacity and longer sleeves that accommodate more bumper or iron plates, it’s built for progressive overload without worrying about maxing out the bar. It’s rackable in most standard power racks, which means you can use it for rack pulls and even loaded carries right off the j-cups.
The honest downside? It costs more, and the heavier bar weight (~60 lbs) means the starting weight is higher for true beginners. If you’re pulling under 225 lbs regularly, you might not need this much bar.

CAP Olympic Open Trap Bar — Full Breakdown
The CAP Olympic Open Trap Bar is the “get it done without overthinking it” option. CAP has been making affordable gym equipment for decades, and this bar delivers basic open trap bar functionality at a price point that won’t wreck your budget. It fits standard Olympic plates, offers dual handle positions, and the open frame lets you load and unload without gymnastics.
The knurling is moderate — fine for most training but not as grippy as the Bells of Steel on max-effort pulls. At roughly 47 lbs, the lighter bar weight is actually a plus for newer lifters or anyone using the bar for higher-rep metabolic work. The 500 lb capacity is plenty for most home gym users who aren’t chasing competitive powerlifting numbers.
Where it falls short is longevity under truly heavy use. The finish can show wear faster, and the shorter sleeves limit how many plates you can stack. If you’re already pulling 400+ and climbing, you’ll feel the ceiling sooner.

Category-by-Category Verdict
Build Quality & Durability
Bells of Steel wins here. Thicker steel, better welds, and a more aggressive powder coat mean this bar is built to take punishment for years. The CAP is functional and solid for its price, but you can feel the difference in hand. Winner: Bells of Steel.
Handle Comfort & Knurling
Both bars offer dual-height handles, which is great. However, the Bells of Steel knurling is sharper and more consistent, giving you a more secure grip on heavy pulls and shrugs. The CAP knurling works fine up to moderate loads but can feel slick if your hands sweat. Winner: Bells of Steel.
Weight Capacity & Sleeve Length
This one isn’t close. The Bells of Steel handles 750+ lbs with longer sleeves for more plate capacity. The CAP tops out at 500 lbs with shorter sleeves. For anyone serious about long-term strength gains, the Bells of Steel gives you far more runway. Winner: Bells of Steel.
Price & Value
The CAP takes this category convincingly. If you’re building a home gym on a budget or you’re a beginner who just wants an open trap bar to learn on, the CAP delivers the core functionality at a significantly lower price. Not everyone needs a 750 lb bar. Winner: CAP.
Portability & Bar Weight
The CAP’s lighter weight (~47 lbs vs ~60 lbs) makes it easier to move around a smaller gym, carry to the garage, or set up for lighter training sessions. The Bells of Steel’s extra heft is a non-issue for dedicated lifters but can be inconvenient in tight spaces. Winner: CAP.
Who Should Buy Which?

- Need longer sleeves to load more plates
- View your home gym equipment as a long-term investment

- Don’t plan to exceed 400–500 lbs on the bar
- Need a lighter bar that’s easier to move around
FAQs
Is an open trap bar better than a closed one?
For home gyms, yes. The open frame lets you walk into a rack, load plates from the side, and do farmer carries without the front bar hitting your legs. You lose a tiny bit of torsional rigidity, but for 99% of home gym users it’s a better design.
Can I do farmer carries with these bars?
Absolutely. The open-ended design on both bars is ideal for farmer carries. Just pick up and walk. The Bells of Steel’s heavier starting weight gives you a built-in challenge even with lighter plates.
Will an open trap bar fit in my power rack?
Most open trap bars, including both of these, are designed to be rackable on standard power rack j-cups. Measure your rack’s inside width to confirm, but both bars fit the majority of home gym racks.
Do I need a trap bar if I already have a straight barbell?
A trap bar isn’t a replacement — it’s a complement. It allows a more neutral grip, reduces lower back stress, and lets you train heavy pulls with less technical demand. The National Strength and Conditioning Association (NSCA) has noted that trap bar deadlifts can produce similar force output with reduced spinal loading.
How heavy can I go on the CAP trap bar?
The CAP is rated to 500 lbs. For most home gym lifters, that’s plenty. But if you’re an experienced lifter who regularly pulls 450+ and climbing, you’ll want the Bells of Steel for its higher ceiling.
What muscles does the trap bar deadlift work?
Trap bar deadlifts hit your quads, glutes, hamstrings, traps, forearms, and core. The more upright torso position shifts emphasis slightly more toward the quads compared to a conventional barbell deadlift.
Are open trap bars safe to use alone?
Yes. One of the biggest advantages of a trap bar is that you can safely bail on a failed rep — you just set the bar down. There’s no barbell rolling over your shins or getting pinned. It’s one of the safest heavy compound movements you can do solo in a home gym.
Final Verdict
For most serious home gym owners, the Bells of Steel Open Trap Bar is the smarter buy. It costs more upfront, but the higher weight capacity, better knurling, and overall durability mean you won’t outgrow it. If you’re building a garage gym where you plan to train for years, this is the bar that grows with you.
That said, the CAP Olympic Open Trap Bar is far from a bad choice. If you’re just starting out, training for general fitness, or working with a tighter budget, it does exactly what an open trap bar needs to do — and it does it well. You can always upgrade down the road if your strength outpaces the bar.
Either way, adding an open trap bar to your home gym is one of the best equipment decisions you can make. Your lower back will thank you, your deadlift numbers will climb, and you’ll wonder why you didn’t pick one up sooner.
