Rear Base Stabilizer 2.0

Rear Base Stabilizer 2.0

Add stability and function to your power rack with the uniquely shaped Rear Base Stabilizer. It is compatible with 4000 and 5000 series racks (PR-4000, PR-5000, Omni, and Apollo). The RBS provides a ton of sturdiness without adding a large footprint. When attached to your rack, this stabilizer even removes the need to bolt down your PR-4000 or PR-5000 with 41” crossmembers (but not with shallower crossmembers, due to stability).

Great to have if you're adding a functional trainer to your rack. I decided to use rogue spacing 43" width, ended up selling

I believe I had to get this when I bought the lat pulldown/low row. It does what it’s supposed to and haven’t really thought about it since I installed it which I suppose is a good thing.

Nice add on for your REP rack. Can be flipped in either orientation to provide more space.
