Roller J-Cup - Force 6

Unlike standard roller cups that rely on nylon or hard plastic rollers, ours feature Delrin® rollers, known for their strength and low-friction properties. Paired with lubricated brass bushings, these cups deliver ultra-smooth racking—even under extreme loads. Whether you’re unracking 135 or 700 lbs, your bar glides into place without resistance.

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.
