Works on my rogue rack
I purchased this base to extend my Rogue RML-490 rack. Works perfect. I get just that extra depth for my bench set up/squats. Highly recommend for anyone looking to keep stabilization and pick up some extra room within the rack.

Quality addition to my set up
I added this to my set up after purchasing a BOS lat pulldown/low row rack attachment off FB Marketplace. Adds significant stability and works as advertised.
Compatible with the Rogue Monster Lite!

Perfect solution for 4 post racks
I have a four post rack with 24” crossmembers that I use as a half rack. Even withblots of plates stored on the rack, I found my rack (from the Other Imperial 3x3 Brand) had a little more side to side play than I’d like. Enter the BoS rear base stabilizer.
This thing is snug to get on, but once in place, removes any side to side movement on your rack. With 1” holes throughout, it also becomes a great place for storing rack attachments that aren’t in use. That the RBS extends backwards means it doesn’t take up any precious room inside the rack, either. Just wish it came in custom colors to match my white powder coat!
