Isolator Side Port Weight Arm

We took one of our most powerful tools—the Isolator—and gave it the upgrade it deserves. This new add-on replaces your center-aligned weight arm port with an outer-facing female port, unlocking a whole new realm of fluid, bi-directional, superset-friendly movement. Translation? You’re about to double down on functionality without changing your entire setup.

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.
