Overview
The GYMAX Olympic folding trap bar (model GM1929) is a 56 inch chrome hex bar built from steel with an 800 lb capacity, dual knurled swivel handles, and a folding frame for storage.
Reviewers repeatedly point out that this bar is sized for standard 1 inch plates rather than true Olympic plates, and several mention the diameter running slightly under 1 inch, which means clamps from other bars may not grip it even though the included clamps work fine. The swivel handles get called out as more comfortable on the wrists than fixed hex bar handles, especially for smaller lifters whose hands sit closer to the frame.

- Folding frame for storage
Who it's for
Fits home gym owners with standard 1 inch plates who want a trap bar for deadlifts, shrugs, squats, and farmer carries without buying true Olympic sleeves. Less suited to lifters who already own Olympic (2 inch) plate collections, since this bar is not built for that sleeve size.
What buyers say
From Amazon customer reviews.
Reviewers consistently describe the welds and finish as solid with no rust or breakage, and several called out the swivel handles as more comfortable than fixed hex bar grips, especially for shorter lifters. The main compatibility note is that this bar is built for standard 1 inch plates rather than true Olympic sleeves, and a couple of reviewers found the bar's diameter runs slightly under 1 inch so external clamps did not grip, though the included clamps worked. One reviewer flagged rough knurling as something to pair with gloves.
