If your idea of spacious is an airplane bathroom, then
you’ll be cozying right up to this 4 Post Folding Rack.

You’re a space-maximizer, I get it.

You have a fold-out bed, you hang your frying pans on the wall, and you secretly love the efficiency of a sweaty crowded subway.

Benefits of the Hydra 3" x 3" Folding Power Rack

    Some need to travel to 30,000 feet before experiencing the joys of a confined space but this isn’t your first (high altitude) rodeo — no, you EMBRACE those close quarters with open wings. Featuring the same 11-gauge sturdiness but taking up a smaller footprint than the 4 post rack, this rack feels as good as an empty seat next to you on a 12-hour flight. And when you’re done setting a new squat PR in the equivalent space of an airplane bathroom, you can just fold away the rack. Guess what they say is true… not all heroes wear capes.
    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" Folding Power Rack

Hydra Rack Feature Highlight 1

Hefty 11-Gauge Steel

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

No Spotter Needed

If you train alone, then you know what it’s all about: your own music, no line-ups, and curls in the squat rack. However, it’s essential that you train safely and that’s why every Hydra rack comes with your choice of pin pipe safeties or spotter straps. Because if you’re in a pickle, you should NEVER hesitate to dump a loaded barbell.

Frequently Asked Questions

The uprights on the Hydra 3″ x 3″ Folding Power Rack measure true 3″ x 3″, which is exactly 76.2mm x 76.2mm with 5/8″ holes.

Once assembled, the Hydra 3″ x 3″ Folding Power Rack’s dimensions are:
  • 47.5″ or 60.5″ length (depth) with stringers
  • 49” width
  • 72, 84″, 90″, or 108″ height

*Remember that the front edges of the upright base plates extend by 2.5″, the uprights are 3″ deep, and the stringers add 1″ of depth — resulting in a total 47.5″ or 60.5″ depth.

The Hydra 3″ x 3″ Folding Power Rack weighs a minimum of 295lbs when the smallest uprights & cross-pieces are selected with no attachments.

When bolted securely with the rack’s feet firmly in contact with the floor, the Hydra 3″ x 3″ Folding Power Rack’s weight capacity is 1,000lbs.

The steel thickness on the Hydra 3″ x 3″ Folding Power Rack is 11-gauge/2.9mm.

Both sides of the Hydra 3″ x 3″ Folding Power Rack can be folded inwards on the 24″ and 30″ depths with the folded rack extending out just 12″ from the wall. To do this, put a bolt through the REAR middle hole of the wall mount hinge and the REAR hole on the 8″ wall connector piece on one side, then put a bolt through the FRONT middle hole of the wall mount hinge and the FRONT hole of the 8″ wall connector on the other side. By mounting the connector pieces in this offset pattern, the uprights can fold inwards — one over the other.

Only attachments designed to fit true 3″ x 3″ uprights are guaranteed to fit on the Hydra 3″ x 3″ Folding Power Rack. Attachments for uprights that measure 75mm x 75mm (often labeled as 3″ x 3″ but are based on the metric system and are actually 2.95″ x 2.95″) will NOT fit on the Hydra rack.

To assemble the Hydra 3″ x 3″ Folding Power Rack, you need two 24mm wrenches (not included by default). Correctly sized box-end, adjustable & socket wrenches are suitable alternatives.

Covered under our Limited Lifetime Warranty guarantees that the Hydra 3″ x 3″ Folding Power Rack will not break under normal use, and protects against defects in material, function and workmanship.
