ISO Arms

No. They are only for use on the outside of the rack.  

Start by installing them as far down as possible. Starting at the bottom allows the weight of the arms to be supported by the ground. During use, we suggest using additional pins to lock them in place. This allows you to use the second weight horn as a second handle for ease of adjusting.  

Yes, they work with the SR-4000. Technically they also work with the PR-4100, but we do not recommend using this attachment, as it could possibly lead to wall damage if the rack isn't mounted properly. The spacing of the brackets on the PR-4100 also limits the functional range of the ISO Arms.

Yes (4000 Series option). Make sure you choose the right series for your rack. Note: If you have the PR-4000 Power Rack, you will only be able to use one pin to secure each ISO Arm to the upright due to the hole spacing on the brackets. The arms are still safe and useful. 

Yes, but you can max out on the height of the upright. The 80” uprights provide a limited range, because the shorter rack has fewer holes and less space. 

Yes, if used on a PR-5000 or PR-4000 power rack. The Apollo Half Rack and Omni Rack do not need to be bolted down to use the ISO Arms.

We cannot guarantee compatibility between REP items and non-REP items due to manufacturing and machining differences. 

No, they even have a plastic lining that protects the powder coating on your uprights. Moving this product up and down may leave behind some temporary residue from the protective lining. 

You can do all kinds of exercises: rows, deadlifts, squats, a variety of presses, belt squats, hip/glute thrusts (with leg roller attachment), monolift bench presses, banded jumps, and more. Or lock them securely in place for exercises like dips, L-sits, and pull-up variations.  

The arms are heavy duty, made from 3x3” 11-gauge steel. You can fit up to seven 45lb iron plates on each arm. 

The springs clips included. REP's standard spring clips are too big.
