Adjustable Jammer Arms™

An industry first, the Sorinex Jammer Arms were designed with future innovation in mind. In the late 2000’s, Sorinex introduced the rack attached Jammer Arms. Many coaches wanted to utilize traditional jammer press movements but did not want to sacrifice floor space in their weight rooms. Sorinex created an innovative training solution that has now evolved in the Adjustable Jammer Arms. As coaching philosophies changed and new training environments were created, the Jammer Arms answered the call. Fast forward to 2023 and our progress continues with improved modularity, functionality, safety, and branding.

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.
