The Hydra 2-Sided Rack Builder delivers elite team training efficiency without demanding the space of a full Hydra Rig.
Everything you see is included — 84" uprights, 30" crossmembers, 13" plate pegs, and more. Each upright measures a true 3" x 3" (exactly 76.2 mm x 76.2 mm), unlike the typical 75 mm imports from other brands.
Thanks to this precision spec, the Hydra is compatible with a wide range of American-standard attachments — no brand loyalty required. Its modular design means you can reconfigure or split it into smaller racks for home gyms, family workouts, or team training setups. And yes, it’s perfect for those “swolemate” lift sessions, too.
IMPORTANT: The Hydra series uses true 3" x 3" tubing with 5/8" holes. Only Hydra attachments or non-B.o.S. attachments built precisely for 76.2 mm x 76.2 mm uprights with 1" holes will fit.
