Benefits of the Hydra 3 x 3 Inch Flat Foot Power Rack

    The 4 post Flat Foot power rack is the granddaddy of all rack configurations. If you want your rack to outlast heavy squats, handle big bench presses and withstand a set of chin-ups with 8 kids latching onto your waist, then this is the rack to get. This bad boy weighs a hefty +250 pounds and unlike the Flat Foot Rack, its design is ultra-stable — so you don’t have to bolt it down before trying for that new chin-up PR. Oh, and did we mention you’ll fit in with the cool crowd with this rack? *wink wink*
    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 Inch Flat Foot Power Rack

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 Flat Foor Feature

No floor bolts required

Flat foot racks have the distinct advantage of not having to anchor to the floor, simply attach the flat foot and voila, you are ready to set PR’s.

Our flat foot supports come in 56″ and 62″ lengths, with an optional 43″ flat foot crossmember to connect them for added stability.
