Overview
A 47-inch chrome EZ curl bar with threaded sleeves for standard 1-inch weight plates, sold with two spinlock collars for a home gym setup doing curls, extensions and presses.
One reviewer replaced a two-piece competitor bar that snapped at its welded center joint under 90 pounds of plates, and rated this one-piece solid bar higher on that basis alone. The angled EZ shape is meant to ease wrist and elbow strain compared with a straight bar, though buyers are split on how the finer knurl pattern feels against bare hands.
- 47 inch overall length
- 7.5 inch threaded sleeves on each end
- 13.7 inch grip area
- Ships with two spinlock collars
Who it's for
Home gym users doing curls, rows, extensions and similar accessory lifts with standard 1-inch plates. Not for anyone whose plates or racks are built around 2-inch Olympic sleeves.
Pros and cons
- One-piece solid steel construction, not a bolted joint
- Angled EZ shape eases wrist and elbow strain versus a straight bar
- Affordable relative to other EZ bars
- Spinlock collars can loosen slightly during a set
- Knurl is finer and less grippy bare handed than some other bars
- Bar weight is not printed on the packaging
