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.

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.

Great experience. Found everything I needed to get the home gym off the ground. The YouTube videos for building everything was really helpful and quality is exactly what I would expect.
I bought 2x barenaked bars, the 4 post hydra, buzzsaw bench and a couple other attachments and safeties to round it out. Would definitely recommend.

Very happy with my hydra rack. After using a cheap rack for several years I decided to upgrade to something more substantial. This is a very sturdy rack, the 3x3 uprights and 11 gauge steel give it a commercial gym feel, and the black powder coat gives it a high quality look. I purchased the bolt on straight pull-up bar and the dip attachment and am quite happy with the quality. I also appreciate that the uprights and crossbeams can be purchased separately, in the future I plan on turning my 4 post into a 6 post rack. The customer service is also fantastic, they were very responsive from my experience. The packaging was all high quality, nothing was damaged on arrival. I live locally but shipping was quite fast, my order arrived 3 business days after ordering.
Bells of Steel CanadaHi Colin,
Thank you so much for such a fantastic review of our new Hydra 4 post rack. We are delighted that you are enjoying its beefiness and that you plan on upgrading to a 6 post in the future.We look forward to serving you.

- TWTyler W.Rated 3 out of 5 stars2 years agoThe Small Things
After a month of waiting (Ordered it Nov. 18 and received it Dec. 19) I finally received my rack. Apart the top pieces popping off ever so slightly on all the uprights, the rack is amazing. Welds are great, the lazer-cut numbering is amazing, finish...everything about the rack is great. However, the reason I'm giving it a 3 is because shipping and customer service is honestly a hassle. Took over month to finally receive the rack. I wouldn't be too upset over it (with it being the holidays) if I was able to receive my information or contact support easily enough. Took many trys to talk with someone and each time I did, they said they would send my tracking number and all relevant information to my email. Never did. I was surprised by my rack arriving. I was actually about to try and cancel my order on the day it arrived because i was tired of waiting and not knowing. Well, at least I finally have my rack. So I went to assemble it and all that. Well turns out they never sent the pieces that the safety straps attach to that connect to the rack. This, after ordering the spotter arms initially but was *graciously* upgraded to the safety straps, after being told the arms were on hold till February. I figured the pieces come with it but I guess I was wrong. So now I have a pair of 150ish dollar straps but no safety equipment of any kind. It's this kind of stuff that just gets infuriating...
TL:DR the rack itself is great but the extras associated with it, shipping, and customer…
Bells of Steel CanadaHey Tyler,
Thanks for your email.
I am glad that you are happy with the rack and I appreciate your feedback. I am sorry that you had to wait a long time to get it. There were some inventory issues with the Hydra rack that have since been resolved that caused out shipping times to be delayed and it was quite confusing for the customer service team. I don't want to make excuses but more explain the reasons for these problems.
If you are still waiting for the connectors for the safety straps, please send us an email to support@bellsofsteel.com so that we can get them sent out to you.
Happy lifting!
