Bells of steel(BoS) offer a diverse set of quality equipment. With the addition of there flat feet and previously purchsed rack componemts I built a stand alone manticore upright with a base that can be used with other BoS rack attachments. I can now use my rack system to do side and back delt cable crossovers with the BoS Seal Row Pad attachment. And use rack cable tension with the BoS Boulder Shoulder/chest fly attachment. Solid built equipment and parts.

Don’t forget these when building your cage!
Great product, I forgot to add them to my order when I was building my squat rack. I ordered the feet but not the attachments (my own mistake). BOS was kind enough to ship me the attachments with free shipping which I appreciated

Flat Foot Cross Piece
I bought the flat-foot Hydra system, and it would be rock solid except that I have it set up on carpet. The back cross piece reduced some of the side-to-side movement, but there's still a little left. I have no concerns with any of my lifts or chin-ups, and even muscle-ups would be fine - if I were strong enough to do one! There is no front-to-back movement at all, which is the most important.
