Build your PR-4000 power rack with pairs or sets of 16", 24", 30", or 41" Crossmembers. They are sturdy and heavy-duty, made from 3x3" 11-gauge steel. The 16" crossmembers are typically used for the construction of weight storage (turning your four-post rack into a six-post rack).

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.
