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
Fits all 3x3 racks and select 2x3 racks with 1-inch or 5/8-inch holes — installs on a single upright.
Precision Bearing System
Split-rod design with precision bearings delivers smooth, friction-free barbell travel through the full range of motion.
Lowest Starting Position
The lowest starting height of any modular Smith machine setup — essential for proper depth on hip thrusts, deadlifts, and lunges.
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.

Solids are great
I bought these so I could keep moisturizer on my heels yet keep my toes cool. I love the solid colors but there is absolutely no stretch on the pretty flowered ones. I guess it’s the way they are woven. They are really hard to stretch over the heel. The solid colors are soft and super comfy.

These run small!
I had ordered these before in black and grey and they were great, fit perfect. But these run small. I had noticed another reviewer said the same but thought I'd risk since they were cute. I'm not sure what color has to do with it, but tight at ankle and at 'toe'-less part. They are now in my donate bin. Waste of money, will not purchase this brand again. Great idea, inconsistent quality.

Solid colors fit, patterned ones too small
As others have said, the blue socks with flower pattern were much smaller than the solid blue pairs- so small I couldn’t even get it on my foot (shoe size 8). The solid blue pairs I like and still wear, but it’s a bummer to only have 2 out of 3 fit when they cost this much.
