Overview
A cold-rolled steel triceps bar with a chrome finish and revolving sleeves, measuring 34.25 by 6.69 by 2.76 inches and weighing about 19.28 lbs. Rated for a maximum load of 200 lbs across a 6.5 inch loadable sleeve length.
CAP built this as a dedicated triceps and upper-body bar with neutral, medium-depth knurled grips rather than a general Olympic bar. Reviewers rate the build quality highly, though several report the bar arriving with cosmetic wear, packaging damage, or a used-looking finish despite ordering new.

What buyers say
From Amazon customer reviews.
Reviewers consistently call the build sturdy and the grip comfortable for triceps work like skullcrushers, and several call it good value for a home gym. The clear recurring complaint is condition on arrival: multiple buyers describe damaged packaging, dented end caps, metal chips inside the sleeve, or a bar that looked used rather than new.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sturdy build with a comfortable grip
- Revolving sleeves reduce wrist strain
- Compact and affordable for a home gym
Performance notes
Revolving sleeves are meant to cut down on wrist and forearm strain during curls and extensions, while the medium-depth knurling gives a non-slip grip without being harsh on the hands. The bar's 200 lb load rating and 19.28 lb frame put it firmly in the accessory-bar category rather than a heavy compound-lift bar.
