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.
What buyers say
From Amazon customer reviews.
Reviewers who had a competitor's welded two-piece bar snap under load say this one-piece bar has held up better for the price. Complaints center on the spinlock collars loosening slightly mid-set and needing a quick re-tighten, and on a knurl pattern a couple of buyers found finer and less comfortable against bare hands than other bars they have used.
