Manticore 3 x 3 Inch Four Post Power Rack

Achieve legendary status with the unconquerable 3″ x 3″ 4-post rack with 1″ holes.

It’s beastly. It’s customizable. It’s the last rack you’ll ever need — which takes that scorpion tail sting out of the investment.

Scroll down and start the epic quest of building your perfect power rack. We promise it’s a lot easier than the Labours of Hercules.

FEATURES • True 3″ x 3″ uprights • 1″ holes • 11-gauge steel • 1,000lb capacity • Black powder coat • Hardware included • Ships unassembled




Simple. Iconic. Everything you need to tame (or unleash) the mythical beast within.

This power rack is to home gyms what hockey is to Canada — reliable, enduring, and a national freaking treasure.

Benefits of the Manticore 3 X 3 Inch Four Post Power Rack

    This Four Post power rack is the Hercules of all rack configurations. If you want your rack to outlast heavy squats, handle weighted pull-ups, and withstand you bench pressing a Nemean lion (pics or it didn’t happen), this is the rack to get. This bad boy is hefty but lacks the upgraded stability of the stable Flat Foot rack, so we’d recommend bolting it down before you go channeling your inner hero. Or villain. You do you.
    Don’t let brand limitations hold you back! Like our Hydra racks, the uprights of our Manticore 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 rack attachments freely without swearing your undying fealty to one brand — Now that’s customization! Just be sure to ask your oracle (Hey, Alexa!) and confirm compatibility BEFORE you start the mix-and-match fest, capiche?
    Customized racks are the best things since personalized sub sandwich shops, and they don’t even have that weird smell. Choose a pre-made design or craft your set-up to your personal taste. Create a bulk order now or build out your home gym over time — the choice is yours. Add some bolt-on plate pegs, a lat pulldown, and some extra pickles sandwich j-cups, just to round out the metaphor. Please?

More LEGENDARY features of the Manticore 3 x 3 Inch Four Post Power Rack

1" Holes and Hardware

1″ hardware is a must for heavy-duty lifters. This bomb-proof hardware ensures that your strength equipment is secure and stable even when the music is cranked and the weights are flying. Oh, and it will keep your rack standing for longer than it takes to read Homer’s The Odyssey. No… not that Homer.

Side Keyhole Slots

Ready to settle for 1″ holes on all 4 sides? Nah, your inner Swoledilocks deserves “just right” all day, every day. That’s why we went with keyhole slots on the sides of the uprights, so you can side-mount your 5/8″ attachments… as long as they’re destined for true 3″ x 3″ tubing — perfect if you prefer the more economical Hydra rack attachments. Now that’s a fairy tale come true.

Laser Cut Numbers

Trying to line up your j-cups or safety straps is arguably the hardest exercise. Fortunately, your days of cursing as a warm-up are over! No more fumbling around trying to guess the right setting — the laser cut numbers ensure perfect balance every time. Now you can go back to doing real gym math: counting by 45s.

Hefty 11-Gauge Steel

Built with 11-gauge steel, this mythical beast can handle the weight capacity needs of world-class lifters and old ancient-school Olympians alike. With thicker steel, you get even more stability than our Light Commercial Rack, which means less shaking when racking your barbell or while using attachments. Even if it’s not bolted down, you’ll feel that true #heavyweight status.

First of all, shout out to the Calgary staff for their excellent customer service over the years. Brandon has been awesome since forever but special thanks to Garvin (sp?) and Matt for helping me get sorted after I ran into some issues with upright heights/rack design. They went above and beyond to help me out and I just wanted it known I really appreciate it. I upgraded from my BoS light commercial to the Manitcore 4 post and this thing is solid. At first I was hesitant on a 4 post design due to stability concerns as my only experience has been with cheaper lighter racks and I am not interested in bolting anything to my basement floor. The Manticore is heavy duty and solid, this thing weighs a ton and is extremely stable even with the 4 post design. I honestly couldn’t tell a difference between it and the flat foot design in terms of stability. Quality is great, easy to assemble, and the modular design is a cool idea as I can always upgrade to a 6 post in the future by adding a couple more pieces if I want to. As for design specifics I opted for a crossmember on both the front and back for extra stability and moved the pull up bar to the middle which has been working great. For reference anyone planning their build I got the 90” upright height, 43” cross member depth, from my understanding the bigger the footprint the more stability, as well I like space inside my rack so I went with the 43” depth as that is what I was used to with my light commercial. My basement height is 96” (unfinished) btw.
