The Leg Extension/Curl Rack Attachment offers a machine-like feel and stability without taking up valuable real estate in your home gym. This beefy attachment has a weight plate capacity of 250lbs and a user capacity of 250lbs.

The Leg Extension/Curl unlocks seated leg extensions, so you can blast your quads but don't forget your hammies! They can be isolated one at a time with standing single-leg hamstring curls for some juicy hams worthy of Sunday dinner. Throw on some resistance bands for tension you can cut with a knife (which we do not recommend).

Choose the Leg Extension/Curl Power Rack Attachment that coordinates with your power rack uprights and hole size.

IMPORTANT: Your power rack MUST be bolted down when using the Leg Extension/Curl to ensure user and equipment safety. For maximal stability, use this attachment on the inside of your rack.

The Utility Horn easily mounts on your rack for quick access to your Olympic weight plates, bands, or chains-whatever you need handy up to 100lbs. It keeps your stuff off the floor to give you more room to smash your goals.

The cotter pin offers extra security and stability while making it easy to move around until you find the perfect spot, and allows you to fit more onto your rack, taking up only one hole on the upright (compared to bolt-on plate pegs, for example, that use multiple holes to mount). The black powder coating offers rust resistance.

As a bonus, you can use it for a step-up to reach the pull-up bar on a rack that's a bit too tall for you, or to help you do one more set of negative pull-ups. 

Choose the utility horn that corresponds with your rack configurations and hole size.

Ready to set a PR in home gym organization? Save space and get even more use out of your power rack by attaching a Vertical Mount Barbell Holder on the front or back of your uprights.

Two bolts offer easy mounting, while an inner liner protects your barbell.

The black powder coat offers rust resistance, and the 220lb max capacity can handle your barbell, even if you use it as a makeshift coat rack (please don't).

Choose the Vertical Mount Barbell Holder that corresponds with your power rack measurements. Hardware included.

IMPORTANT: If your ceiling is less than 9 feet high, you may find using the Barbell Holder challenging with a standard barbell - please keep this in mind prior to purchasing.
