Benefits of the Hydra 3" x 3" Power Rack - 6 Post

    The 6 post power rack is the supercharged version of the classic 4 Post Rack. If you want your rack to command the room like a military drill sergeant (minus the enraged screaming and crazy eyes), then this is the rack for you. Plus, it’ll show your weight plate collection off better than your grandma’s china set — take that, Gam-Gam. Don’t worry though, I’ll still wear your hand-knitted sweater this Christmas.
    If you’re a die-hard fan of the metric system, then listen up: the uprights of our Hydra racks 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 who make their racks on US soil *respectfully tips hat*, you can mix and match attachments freely without needing to stick to one brand — hello, open ecosystem! Just be sure to research thoroughly BEFORE you begin the mingling shenanigans, deal?
    QUICK! Name three things in life you can’t live without. I’ll go first — pockets, sliced bread, and… a customizable power rack 😎 Choose a pre-made design like you see here or build your own piece-by-piece. You can always add separate components later when you’re ready to expand your unit with weight plate storage, or divide and conquer by splitting your rack into two collegiate-style racks for double the fun. As you can see, we put a lot of thought into this… our mom would be SO proud.

More AWESOME features on the Hydra 3" x 3" Power Rack - 6 Post

Hydra Rack Feature Highlight 1

Hefty 11-Gauge Steel

Built with 11-gauge steel, this bad boy can handle the weight capacity needs of world-class lifters. You get even more stability than our Light Commercial Rack which means less shaking when racking your bar or while using attachments. Even if it’s not bolted down, you’ll feel that true #heavyweight status.

Hydra Rack Feature Highlight 2

Laser Cut Numbers

Trying to line up your j-cups perfectly can be a pain in the you-know-what. And unlike many of our competitors, we have lasered numbers every 1-2 holes to make adjustments a breeze. So you can easily change your j-cup height after your widow-maker squat set… because counting is HARD WORK when you can barely breathe.

Hydra Rack Feature Highlight 3

1" Spacing in Bench Zone

Ready to settle for 2″ hole spacing throughout? Pffft, not a chance. You are an efficient and optimized MACHINE, that’s why we went with extra precise 1″ hole spacing to make unracking a heavy bar a little easier. After all, every morsel of energy matters when going for that 1lb PR (fractional plates, you da real MVP).

Hydra Rack Feature Highlight 4

Super Storage Extension

Plates, attachments, pegs or even pulls – the additional storage section acts as your ultimate lifting companion. But unlike your workout partner, it will always be there to support you.

Storage options include 5″ & 13″ bolt-on plate pegs, pin-style plate pegs, change plate pegs, and more!
