Smith Machine Rack Attachment - Bar Included
Smith Machine Rack Attachment
BREAKING NEWS: the stigma against Smith machines is over! This Smith Machine Rack Attachment will supercharge your size & strength in an ultra-compact footprint. Now, if only mullets would come back in style…
This widely compatible unit upgrades your 3” x 3” power rack into a beloved bodybuilding beast without the hefty price tag or space requirements.
Bring your own 25-30mm diameter barbell (BYOB) for a higher starting weight and to optimize the attachment for your next training cycle. Or, snag the hollow 36lb Smith bar for an easier assembly & one-and-done solution for all exercises. With a 600-pound total weight capacity, it’s ready for your heaviest ambitions.
Mount this rack attachment on the inside of your rack without taking up any additional footprint in your gym, or attach it to the outside — sitting just 10" off your uprights! Change between a straight or angled bar path with a few simple adjustments to the mounting brackets, making its fixed path feel as natural as possible for your body.
Hit all the staple lifts: squats, presses, rows, and Bulgarian split squats (why are they ALWAYS here?!). But that’s just the start. Incorporate heavy negatives on compounds. Isolate individual muscles with JM presses. You can even rehab stubborn aches in your posterior chain with single-leg Romanian deadlifts.
Recommended Set-Up: Mount the upper brackets to the top of your uprights & the lower brackets to your crossmembers (inside rack) or front foot stabilizers (outside rack). Brackets can be mounted to your uprights only, but a dropped bar could permanently damage the unit.

Kraken Plate Loaded - Single Side
Kraken Rack Attachment for 4 Post Hydra & Manticore Racks (Single Side)
The Kraken is a compact rack-mounted cable system, turning your 3” x 3” 4-post power rack with ⅝” or 1” holes into a dual-handle cable tower with 5lbs to 210+lbs of resistance! All of this while maintaining the use of your barbell and rack attachments.
It comes in two versions:
- Plate-Loaded: use your weight plates to save big bucks
- Weight Stack: a convenient 210-pound stack for quick, no-fuss adjustmentsThanks to the knurled handle, nylon rollers and chrome-coated pop pins, the trolleys are adjustable with a single hand. By using your uprights’ holes for height selections, you can fine-tune the feel of nearly all your cable exercises.
The Kraken saves the clangin’ & bangin’ for your barbell lifts; its aluminum pulleys and dual guide rods deliver the kind of velvety smoothness you'd expect at a commercial gym — but without the crowds, the dude grunting in the corner, and that fit-fluencer hogging the Smith Machine for “just one more angle.”
The dual aluminum handles have 6002 bearings, rotating as smoothly as a barbell, and allow bilateral exercises from a single upright. A single cable features a 2:1 pull ratio (10lbs feels like 5lbs), tackling everything from rehab work to isolations. Plus, the cable travel offers uninterrupted focus during sport-specific drills or while getting that joooooicy bicep pump.
When connected with the cable adapter, the Kraken converts into a glorious 1:1 pull ratio — perfect for heavy lat pulldowns & low rows — with no need to buy a separate weight pack expansion down the road.
Safety is no afterthought either — the Weight Stack version features an optional Shroud that does double duty: protecting fingers (big and small) AND acting as a pegboard, keeping your cable attachments neatly stowed using their included hooks. This means more family time while keeping your little ones safe… because a home gym shouldn't need a “Caution: Dangerous Sh*t EVERYWHERE” sign.

Utility Horn Rack Attachment
The Utility Horn easily mounts on your rack for quick access to your Olympic weight plates, bands, or chains-whatever you need handy up to 100lbs. It keeps your stuff off the floor to give you more room to smash your goals.

The black powder coating offers rust resistance.
As a bonus, you can use it for a step-up to reach the pull-up bar on a rack that's a bit too tall for you, or to help you do one more set of negative pull-ups.

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.

- JjasonVerified BuyerRated 5 out of 5 stars5 months agoQuality 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!

This is an awesome rack. It is extremely sturdy and can be added onto. I added two more posts to sides of mine for plate storage. It’s the best rack I have ever owned and the accessories are strong and affordable.

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…
Bells of Steel CanadaHi Damen, Thank you so much for the awesome review of our manticore today. We are delighted you have enjoyed your new rack and that it has worked well for your setup. We thank you for your business and kind words. Let the gainz begin! Yours in strength, Marcus & the BoS team - HHarryVerified BuyerRated 5 out of 5 stars6 months agoExceeds my high expectations - lifetime purchase without question
I've been waiting for my pre-order for about two months...Over that time I've worried as to whether I would regret the BOS quality relative to a REP or Rogue rack..I wasn't looking to pinch pennies for this buy and was convinced by Gluck reviews that Manticore is legit and a no brainer as a Canadian....having just received all the parts and assembled the finished product, I am absolutely stunned by the quality and therefore value of this rack - especially as a Canadian consumer.
You can surely find more premium attachments like the dip station and landmine attachment from the likes of Rogue, but the rack and safeties along with mag pins leaves absolutely nothing to be desired...completely top-notch...one of the most premium feeling items in my premium home gym.
This is one of those few purchases that I know will be a lifetime purchase. Well done, BOS!!!
Bells of Steel CanadaHI Harry, Thank you so much for the awesome review of our manticore rack.
