ISO-Claw

ISO-Claw

The ISO-Claw is the no-nonsense solution for building brute strength through overcoming isometrics—without the need for a specialty J-cup. Designed to mount directly above our 2-inch sandwich J-cup, the ISO Claw locks into your rack with a speed pin or hitch pin for rock-solid stability. Drop it in, set your bar, and push or pull against immovable steel to overload your nervous system and recruit max force. Crafted from 1/4-inch American steel and hand-welded in the USA, the ISO Claw is built to survive anything you can throw at it. Each unit is lined with 1/4-inch and 1-inch thick UHMW plastic, ensuring your barbell and rack stay fully protected—no scratches, no damage, no compromise.

What is a Rack Attachment?

What rack attachments are

Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.

Compatibility comes first

An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.
