This precision-engineered linear bearings deliver a smooth, consistent bar path that rivals full standalone Smith machines. Once installed, the travel feels stable and controlled—ideal for both strength and accessory work.
Fits Hydra, Manticore, our 84" Light Commercial racks, and most 2.3"–3" non-BoS racks with 5/8" or 1" holes—no proprietary lock-in required. If your rack is at least 72" tall and 47"–49" wide, this attachment integrates cleanly
select between a built-in Smith bar or the BYOB (Bring Your Own Barbell) variant, which lets you use your preferred barbell inside the guided Smith track. Keep the knurling, shaft diameter, and feel you trust—without giving up the safety and control of a Smith machine.
Get full Smith machine functionality without sacrificing an entire corner of your training space. This attachment delivers the controlled bar path of a commercial unit while keeping your footprint the same.
This guided bar path increases safety for benching, squats, and pressing when you train without a spotter. Secure J-hook engagement and smooth vertical tracking give beginners and advanced lifters the confidence to push harder.
Thick-gauge steel, welded guide rod mounts, and reinforced attachment points keep the bar path rigid under heavy loads. Everything is engineered for stability: no wobbling, shifting, or flex even during hard sets.
Overview The Smith Machine Rack Attachment turns your existing rack — Hydra, Manticore, 84" Light Commercial, or most 2.3"–3" racks — into a smooth, guided Smith machine without stealing a single additional inch of floor space. Sneaky, right? Pick the classic built-in Smith bar, or go BYOB (Bring Your Own Barbell) and run your favorite bar inside the guided rails. You get the safety and consistency of a Smith, plus the familiar feel of the bar you already know and love. More control, more confidence, fewer "please don't let this rep be the one that takes me out" moments. Recommended Set-Up: Mount the upper brackets to the top of your uprights & the lower brackets to your crossmembers (inside rack) or front foot stabilizers (outside rack). Brackets can be mounted to your uprights only, but a dropped bar could permanently damage the unit.
