PR-4000 Rack Uprights
Build your PR-4000 power rack with either pairs or sets of 80" or 93" rack uprights. These uprights are sturdy and heavy-duty, made from 3x3" 11-gauge steel. The uprights are compatible with various attachments to add more options to your power rack, and they feature laser-cut numbering every fifth hole that makes it easy to arrange attachments.
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.
