Product Features

  • CLASSIC 4-POST RACK

    This 4 post power rack is the granddaddy of all rack configurations. Laser-cut numbers to easily line up rack attachments. Beastly 1,000-pound capacity and ultra-stable 11-gauge tubing. Everything you need to tame (or unleash) the mythical beast within.

  • CROSS-BRAND COMPATIBLE

    Don't let brand limitations hold you back! The Manticore features industry-standard tubing & hole sizing, so you can freely use matching-spec rack attachments from other brands. See? You don't have to swear allegiance to us forever.

  • NEVER UPGRADE AGAIN

    You know what they say: buy once, cry once. The Manticore is highly customizable with its modular components, so it can adapt with you through every phase of your life. It's the last rack you'll ever need — which takes the sting out of the investment.

Product Details


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! You can even side-mount your 5/8" attachments (as long as they're destined for true 3" x 3" tubing) using the side keyhole slots; perfect if you prefer the more economical Hydra rack attachments, now that's a fairy tale come true!

Built with modular components, so you can expand later or divide it into two smaller Manticore racks to accommodate a new home gym space or team workouts with your swolemate.

Compatible with all Manticore rack attachments, like the hyper-versatile Manticore Lat Pulldown.

IMPORTANT: The Manticore series of power racks are TRUE 3" x 3" tubing with 1-inch holes, so only Manticore attachments & non-B.o.S. attachments made precisely for 76.2mm x 76.2mm uprights with 1-inch holes will fit.

    Great Experience

    I’m extremely happy with my Bells of Steel Manticore squat rack. The quality is excellent—it’s a heavy-duty rack that is very well put together, with neat, clean welds and a solid, stable feel. It’s versatile for a wide range of exercises, with a large selection of attachments + extra compatibility with other true 3x3 posts. It feels like a rack that is built to last.

    The customer service was excellent. I worked with a sales representative while designing and purchasing the rack, and they were very helpful, knowledgeable, and responsive throughout the process. I bought a combo with the lat pulldown attachment and wanted to minimize the overall footprint. I also had specific limitation with ceiling height. We worked together to design the most efficient solution. Having someone available to answer questions and help with the design made the whole experience much easier.

    Shipping and delivery were generally great as well. I received the full pallet within a week, and everything was wrapped and packaged very well. One box was missing from the shipment, but Bells of Steel shipped it out immediately. Most importantly, nothing arrived damaged or scratched.

    Overall, I’m very impressed with both the Manticore rack and the buying experience. Great build quality, excellent customer service, and a smooth delivery process. I would definitely recommend it.

    Thank you so much for the incredible review! We're thrilled to hear your Manticore squat rack is delivering the heavy duty quality, stability, versatility, and long term durability you were looking for.

    It's especially great to hear that our team could help you design a setup that worked around your ceiling height while keeping the footprint as efficient as possible. That's exactly the kind of problem solving we love. We're also glad we could quickly get that missing box on its way and that everything arrived safely and scratch free.

    Thanks again for trusting Bells of Steel with your home gym. Here's to many years of strong training on that Manticore! 💪

    Amazing piece of kit!

    Watched a lot of reviews and compared different options but settled for manticore from bells of steel. I was a bit apprehensive before it arrived as it’s not a cheap piece of equipment but I was set on getting solid, good quality rack.

    As soon as it arrived and I saw the solid and really well finished uprights, then started to assemble and saw how good everything fitted together I actually thought this is a bargain for the price.

    The thing is built like a tank, lat pulldown is smooth as a butter and smith machine is mint. I mean my house insurance halved straight away cause if the roof caves in this beast will not budge.

    And it definitely looks the part as well 😍

    I honestly don’t think you can get better for the price 💪👊💪

    Manticore

    George at the Indy showroom built me out a full Manticore rack. He was very professional and accommodating. The rack is bulletproof and the finish is gorgeous. George understood my price point and future plans so this rack is set up for expansion with very little effort. I will certainly be back and will bring friends.

    PS- you cannot beat the magnet pin system. I don’t know if it’s common in rack builders, but it feels so fancy.

    Thanks for the awesome review!

    It is awesome to hear that George took such great care of you at the Indy showroom. We are happy that your Manticore rack is everything you hoped for. The bulletproof build and gorgeous finish are exactly what we strive for.

    That magnetic pin system really is a game changer, isn’t it? It adds that extra touch of quality and ease of use to the setup. We love that you are already thinking about future expansions. We can't wait to see you and your friends back at the showroom soon.

    Yours in strength,

    The B.o.S. Crew.

    Quality Rack and my 1st BoS purchase.

    I've been wanting a rack for years and finally bought this model after lots of window shopping. All the pieces are quality built and once assembled its absolutely solid. Being able to mix'n'match with other 3x3 racks is nice if you have different pieces already. Built it alone and had no problems. Actually used my bench in it's stored position and a tie-down to hold the post for me . :)

    Needing a rack you won't be dissapointed.

    Now you guys just need to make a helpline so I can call because I'm hooked on the Company!
