Overview
The CAP RB-47TB is a 47 inch EZ curl bar made from solid steel with a chrome finish, threaded on both ends for 1 inch standard weight plates and shipped with two spinlock collars. The angled bar shape is built for curls, extensions and rows rather than for use with Olympic sized plates.
This is a plate loaded accessory bar, not a complete weight set: you supply your own 1 inch standard plates, and the two included spinlock collars are what keep them from sliding during a lift. The angled EZ shape is the main functional difference from a straight bar, meant to put less strain through the wrist during curls.
- 47 inch length, solid steel with chrome finish
- Threaded ends fit 1 inch standard plates
- Two spinlock collars included
- 13.7 inch grip area, 7.5 inch sleeves per side
Who it's for
Fits home gym owners who already have or plan to buy 1 inch standard plates and want a dedicated curl bar for arm work. Not a fit for anyone using Olympic 2 inch plates, since this bar is sized for standard plates only.
Strengths and trade-offs
Drawn from this product's published specifications.
- Solid steel construction with a chrome finish
- Includes two spinlock collars for securing plates
- Angled shape aimed at reducing wrist strain during curls
- No buyer reviews yet to confirm long term wear
- Fits 1 inch standard plates only, not Olympic
- Grip area may be tight for taller lifters
Performance notes
The bar's angled EZ shape is meant to reduce wrist and elbow strain compared to a straight bar during curls, tricep extensions, upright rows and reverse curls. Weight plates thread onto the 7.5 inch sleeves on each end and are secured with the included spinlock collars, while the 13.7 inch grip area in the middle sets how wide or narrow you can position your hands.
