ONYX Smith Machine Attachment Turn your power rack into a full Smith machine. The ONYX Smith Machine Attachment bolts directly onto your Power Rack, adding guided vertical-track training without eating up your floor space or budget on a standalone machine. Get the safety and consistency of fixed-path pressing and squatting while keeping the full functionality of your rack intact. Precision linear bearings guide the barbell smoothly along the vertical track, giving you controlled, stable reps for squats, bench presses, shoulder presses, and more — ideal for training alone, pushing to failure safely, or dialling in form without worrying about bar path. The hook-and-rotate locking mechanism lets you rack the bar at any point along the track, so you can self-spot on heavy sets without a training partner. Engineered from heavy-duty steel with a durable powder coat finish, the attachment is built to handle serious loads rep after rep. The bolt-on design integrates directly with your existing ONYX Power Rack uprights — no separate frame, no wasted space, just added capability. Key Features: Bolts directly onto ONYX Power Rack uprights — no standalone frame required Smooth linear bearing system for consistent, guided bar path Hook-and-rotate barbell locking for safe, solo training Heavy-duty steel construction, durable powder coat finish Supports squats, bench press, shoulder press, and more Space-saving design — full Smith machine function, zero extra footprint Guided strength. Zero compromise. Stay ONYX.
