Turn Your Rack Into a Smith Machine.

The BOB Smith Machine Rack Attachment by Fringe Sport transforms any 3x3 power rack into a fully functional Smith machine — no separate equipment purchase or additional floor space required. Featuring precision bearings, a split-rod design, and the lowest starting position of any modular Smith setup, the BOB delivers controlled, friction-free barbell movement for squats, hip thrusts, bench press, lunges, and more.

Key Features

3x3 Rack Compatible

Precision Bearing System
Split-rod design with precision bearings delivers smooth, friction-free barbell travel through the full range of motion.

Quick-Release Safety
Quick-release barbell mechanism lets you safely rack or drop the bar at any point during the lift.

Description

The BOB Smith Machine Rack Attachment is designed for lifters who want Smith machine functionality without dedicating floor space to a standalone unit. It attaches to a single upright on your existing 3x3 power rack and stays close to the frame, keeping your training area clear for other movements.

Precision bearings and the split-rod design create a controlled, friction-free barbell path that feels smooth and consistent through every rep. The quick-release mechanism provides a reliable safety system — allowing you to rack or release the bar at any point during a lift without fumbling with hooks or catches.

The BOB offers the lowest starting position of any modular Smith machine setup on the market. This is critical for movements like hip thrusts, low-bar squats, deficit deadlifts, and lunges where bar height at the bottom position directly affects range of motion and exercise effectiveness.

The pass-through bracket adjusts easily to different rack heights, and the BOB can be installed on either side of your uprights depending on your gym layout and training preferences. When secured using the hook and clips, the attachment adds approximately 17 lbs to the total barbell weight.

Backed by Fringe Sport's lifetime warranty.

What racks does the BOB fit: The BOB fits all 3x3 power racks and select 2x3 racks that use 1-inch or 5/8-inch holes.

How much weight does the attachment add to the bar: When the bar is secured using the hook and clips, the BOB adds approximately 17 lbs to the total barbell weight.

Can I install the BOB on either side of my rack: Yes — the BOB can be mounted on either side of your uprights depending on your gym layout and training preferences.

Great for bored dogs
Color: Flip Board, Size: Level 2
Great dog puzzle! My pup loves this, he did chew the peg portion once he got them out so they can be put back in. They are tough for small dogs to get out so I think he plotted it out.

Actually Holds up
Color: Knuckle Bone, Size: XX-Large
I must say I had low expectations when buying this bone based on prior experience of similar products. I'm happy to say I was pleasantly surprised. I bought this bone off Amazon in the beginning of December, I wanted to wait a while for my review to see if it would actually hold up. So far so good. There are several factors that set this bone above similar products. First let me be clear that this is the Beef bone not the chicken etc. (I'm told there is a huge difference) 1. The first thing that impressed me is that my dog actually loves to chew on it. I know this may sound weird but I tried the puppy pack of nylabones and a bit larger one. He was interested in them but it didn't last and he wouldn't touch them anymore. This bone on the other hand is his absolute favorite. He carries it around everywhere. Even though it's beef flavored it doesn't have a noticeable smell or residue and it doesn't get slimly like a real bone. 2. This bone is extremely durable. I have a chew happy 10 month old lab puppy with razor teeth and majoring chewing skills. Trust me, my ruined shoes are proof :) It's been almost two months and I can just see where the bone has worn down. The down side to this is it is extremely heavy, not ideal to be leave around to step on, especially because of the way the bone breaks down. As they chew on it is almost peals away into tiny, tiny chunks. This is great compared to a kong stick that he had where he was swallowing large pieces of a rubber/plastic material. The downside is that as it "peals" it leaves the bone very sharp, with little spikes around where they chew. So far my dog doesn't seem to mind and it doesn't seem to make his mouth bleed or anything so that's a minor negative. Just don't stub your toe on it! Trust me! Overall after trying multiple brand/types and flavors this is the only one that gets my seal of approval.

This is a great option for tough chewers
Color: Knuckle Bone, Size: XX-Large
This is a great option for tough chewers, although if your dogs are anything like ours, there is a procedure to ANY new toy no matter how "tough". If I gave them this Nylabone and they went unsupervised day one, they would wreck it and it'd be in the trash within the hour. I say this to tell you, if you have a top 10 bite strength aggressive chewer, that you shouldn't expect a miracle. If instead, I give it, take it away when they are working it too hard or being particularly destructive, and then give it back- and do this a few times for a week or so, then they'll chew it in a less aggressive fashion- they'll enjoy it and it lasts a long time. I don't know what it is about the first few days, but when something is "new" it has to be destroyed. When it's been in the house a few days, they are rough but not as bad. Like the ones listed "virtually indestructible" will last 6 months as long as we have multiple around. It will show damage, there will be shrapnel in the carpet that will scratch up your feet, but it'll be worthy of play still. I consider 6 months in our house worthy of 5 stars. This has been true for 2 Dobermans and a German Shepherd- and all of them have proven ability to destroy these products day 1 if I don't behave appropriately on introducing the new toy. If your dog wrecks these in the first 10 minutes, I'd say you probably need to work on supervising new toy play, and taking it away when they become to aggressive. This is a training issue, it can be done!

Lasting longer than 6 months, longer than any bone to date.
Color: Mega Knot Bone, Size: X-Large
Finally a bone that has lasted longer than 6 moths so far. I know my dog is a chewer. Well worth the cost to not have to replace them as often.
