Bells Of Steel Hydra Four Post Power Rack Builder (3" x 3", ⅝" Holes) - 4-PST-HDR-BLD

The 4 Post Power Rack is to home gyms, what maple syrup is to Canada: world-renowned, and the sign of impeccable taste. *chef's kiss*

It outlasts heavy squats, handles big bench presses and withstands chin-ups with 8 kids hanging onto your waist - just bolt it down before you go trying for that new chin-up PR. The uprights measure true 3" x 3" which is EXACTLY 76.2mm x 76.2mm, instead of the typical 75mm x 75mm uprights of other brands' imported racks.

By matching the same tubing specs as many of our American competitors, you can mix and match attachments freely without needing to stick to one brand - hello, open ecosystem! Built with modular components, so you can expand later with Hydra components or divide it into two smaller to accommodate a new home gym space or team workouts with your swolemate.

Compatible with all Hydra rack attachments, like the hyper-versatile
