62" Flat Foot Attachment
Hydra Flat Foot Support System
Compatible with non-flat-foot Hydra power racks, our flat foot support system includes flat feet, reinforcement plates, and hardware to hold everything together.
The flat feet come in 56" and 62" lengths, with an optional 43" flat foot crossmember to connect them for added stability.
The 56" length can be paired with the 30" or 24" cross member depth, while the 62" length can be paired with the 43", 30" or 24" depth. Popular combos are 43" with a 62" flat foot for maximum roominess. 30" with the 56" flat foot for maximum stability and minimal space. Or get a little weird with the 24" depth and 56" flat foot.
You can select the flat foot with a bottom cross member that connects the 2 feet for increased stability, or leave it out. However, the bottom cross member is NOT compatible with the lat pulldown attachment - you'll need a rear base stabilizer instead.
IMPORTANT: The flat foot support system adds 2-1/4" to the overall height of your rack. Compatible with non-Flat Foot Hydra power racks only.

Lever Arms + Closed Handles
Lever Arms Rack Attachment
Hydra Lever Arms simulate DOZENS of machine exercises in only a fraction of the space & without a jaw-dropping price tag. Add an Adjustable Pull-Up Bar for even more versatility (hip thrusts and leg presses, anyone?)
Height and handle adjustments are simple, so you can find your perfect placement.
These space-efficient attachments (sold in pairs) add only 4.5" to the front of your rack when not in use and tuck nicely inside racks with a minimum 43" depth.
With a 500lb weight capacity and two handle styles to choose from, you're set for life.
Throw on your Olympic weight plates and a set of magnetic collars, and get lifting. Your gainz depend on it.
IMPORTANT: The Hydra Lever Arms are only guaranteed to fit on true 3" x 3" uprights with 5/8" holes. If installed on the exterior of your uprights, your rack MUST be bolted down to avoid tipping and/or injury.

12" Utility Horn
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 (or 132lbs for Manticore). It keeps your stuff off the floor to give you more room to smash your goals.
The cotter pin offers extra security and stability while making it easy to move around until you find the perfect spot, and allows you to fit more onto your rack, taking up only one hole on the upright (compared to bolt-on plate pegs, for example, that use multiple holes to mount). 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.
Choose the utility horn that corresponds with your rack configurations and hole size.

EXTRA-STABLE DESIGN
The flat foot support system offers sturdiness to avoid accidental acrobatics. Its large contact surface area makes the rack extra stable for racking/unracking your bar, during pull-ups, and when doing dips. Bolting is recommended if using spotter arms, though.

WIDE-OPEN SQUATTING
Need room for your inspiring and not-at-all embarrassing post-PR dance? Squat Stands are perfect for those who can't be tamed by the constraints of a 4 Post rack and want the footwork space that our classic Squat Stands can't offer.
Product Details
This squat stand is to home gyms what the Double Double is to Canada — simple, powerful, and a cultural phenomenon.
Its 1,000-pound capacity 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! Built with modular components, so you can expand it later with Hydra components into a larger Hydra rack to accommodate a new home gym space or team workouts with your swolemate. Compatible with all Hydra rack attachments, like the hyper-versatile Hydra Lat Pulldown.
Awarded Garage Gym Reviews' Best Squat Rack with Pull-Up Bar in 2024!
IMPORTANT: The Hydra series of power racks are TRUE 3" x 3" tubing with 5/8" holes, so only Hydra attachments & non-B.o.S. attachments made precisely for 76.2mm x 76.2mm uprights with 5/8" holes will fit.

- JCJacob C.Verified BuyerRated 4 out of 5 stars1 year agoGreat Rack at a Great Price, Packaging Could Be Improved
I scoured all the options for racks on the market and eventually settled on the BoS Hydra because it seemed to be the best value 3x3 rack at the 90" height I needed it to be and the base width I needed it to be - not to mention I can easily expand it as my fitness journey progresses. I am mainly using it as a super-expensive pull-up bar for bodyweight and calisthenics exercises right now and it's plenty stable with the 62" flat foot attachments without being bolted down. I really appreciated that I could order the rack without the J-cups that I won't be using anytime soon and not have to pay for that part of the build. I'd have liked the pull-up bar to have a little more texture to it, but that's nothing I can't improve on my own inexpensively.
My one and only gripe is the packaging. A couple of the boxes containing the parts arrived in pretty rough shape, with the parts completely exposed and the powdercoating scuffed and chipped. I think the packaging could be improved by increasing the size of the box just a bit and adding a little extra padding around the corners of the uprights so that the sharp edges of them aren't right up against the cardboard and as likely to burst through the cardboard and become entirely exposed during transit.
Bells of Steel CanadaHi Jacob, Thank you for reviewing our rack today. We are so pleased to hear you have had a positive experience buying from us and we hope we can serve you again soon. We will certainly put into consideration the packaging in the future as well, thank you for your feedback. Sincerely, Marcus & the BoS team - THTyler H.Verified BuyerRated 4 out of 5 stars2 years agoBest rack for the price
I love this rack I got it during the presale with a couple of attachments and it’s one of the few squat stands I feel comfortable going heavy on instead of needing a full power rack. The spotter arms for it have already saved my life a few times. My only complaints are that because there’s no UHMW on the inside of the attachments they have scratched it a bit in some places and one of the roller cups didn’t have a bolt all the way in for the UHMW pad which scratched the coating on one of bars until I noticed and makes me a little concerned about corrosion in the future. It’s still the center of my gym though and my favorite piece of equipment already trying to decide which attachments to buy next
Bells of Steel CanadaHey Tyler, Thank you for the review on our Hydra Squat Stands and we appreciate the feedback on the attachments and will work to improve our designs. Yours in strength, William & the BoS crew - AAnonymousVerified BuyerRated 5 out of 5 stars2 years agoSolid and Sturdy
I have been pumping iron for more than 40 years. I know weight lifting equipment. This rack is solid. This rack is sturdy. It is a beast. I can do pull ups on it without it moving. I work out with gymnastic rings (beginner) hung from the pull up bar. The rack does not move or shake. I need that kind of confidence as I am a large individual (235 lbs). I buy quality and I seek value. I got both with this purchase.
Bells of Steel CanadaHey there, Thank you for the review, We are happy to have impressed a 40 year iron pumper with our new Hydra 3 x 3 Inch Squat Stand! We hope you enjoy all the gainz you make! Yours in strength, William & the BoS crew - AAnonRated 5 out of 5 stars1 year agoSatisfied
Wanted to buy this solely for calisthenics. Was worried about the stability of the thing, so I went directly to the showroom to try it out (highly recommend this). Purchased it yesterday, and I'm very satisfied with the purchase. The metal seems strong / heavy-duty and the stand does not shake whatsoever for me (I'm 5'8", around 65-70kg, and using this for regular calisthenics- i.e. no momentum / kipping- for context). I like the texture and thickness of the pullup bar. 10/10 would buy again.
Bells of Steel CanadaHi there, Thank you so much for your review of our hydra 3x3 squat stand. We are overjoyed you have enjoyed your new squat stand and we wish you the best. Sincerely, Marcus & the BoS team - SsriramRated 5 out of 5 stars1 year agoVery happy with this 3x3 Rack
Overall super happy with the purchase.
What I like:
Space saver without compromising the functionality and build quality. Exactly what I was looking for. Tried bench press so far and pleased and yet to try Squat workout.
Really really FLEXIBLE that lets you attach any sort of attachment.
Definitely recommend this product especially for a home gym.
What I dis-like or needs improvement:
Bought this from Toronto stores directly & shocked to see that main spare part/Plate with bolts missing in the box and had to drive again all the way 70+ kms. Really request BOS to please ensure sufficient quality control so all needed HW/accessories are inside the box.
Otherwise very much pleased with it.
Bells of Steel CanadaHI Sriram, Thank you so much for the awesome review of our Hydra squat stand. We are so glad you have been pleased with this product, and it has worked well for your needs. We are very sorry about the missing bolts/parts and will ensure this does not happen in the future. Yours in strength, Marcus & the BoS team
