Quick Review Summary

REP PR-4100 folding squat rack is made of 3” X 3”11 gauge steel frame and comes with a pair of j-hooks and a quick-attach pull up bar. The folding mechanism is pretty common and simple to use. The build quality is such that it can last for years of use even when folded or unfolded daily. You can directly attach this rack to the wall or you may buy wooden or metal stringers separately from your local hardware store along with all necessary mounting hardware. The assembly process is straightforward but the assembly instructions are insufficient. Overall, a fantastic product for home use.

The Rep Fitness PR 4100 folding squat rack is available in two different depths 

Nothing extraordinary about it because most competitive squat racks such as the Rogue Monster Lite series foldable wall-mount squat rack and Titan X-3 Series Folding Power Rack too are available in the same depths. 

The two different depths help you buy the most suitable option for your home gym depending on the amount of space you can spare. If you are looking for a really compact squat rack, the 21” should be good for you but do note that due to its short width, you may not feel comfortable while doing kipping and other similar exercises. Plus, you may not be able to position your bench as per your wish. That's why the 41” wide folding squat rack is a better option. 

The 41” rack can be folded left/right and that’s why it stays 24” far from the wall even in its folded position.

If you choose to go with this one, make sure you have this much clear floor space. This is where Rogue and Titan Fitness foldable racks stay ahead of the REP PR 4100 folding squat rack. All their models fold to the center and stick out just 5” from the wall.

The 21” rack, however, folds to the center and sticks out just 6.5” from the wall, just like what you can see in the above image. 

REP Fitness PR 4100 folding squat rack is a beast that can handle anything and everything you throw at it 

The 3” X 3” 11 gauge frame is thick and sturdy enough to handle more than 1000lbs of weight. Plus, the four heavy-duty pins help keep it tightly secured in its position during your workouts, so you experience minimum possible wobble, even if you are performing challenging exercises like kipping. 

The westside hole spacing helps you get to your ideal lift-off height, without making any compromises with your form or comfort. The sides of the uprights too have enough holes so you can add the accessories of your choice. Rep Fitness sells a bunch of accessories that you can add to this folding squat rack but, if you want, you can add accessories from any other brand provided they are meant for 3” X 3” frames. 

The folding mechanism of the REP PR 4100 folding rack functions almost the same as the other best folding squat racks we have selected for you. The process is rather simple. To unfold the rack, you need to unlock the rack from its starting position, bring the uprights away from the wall, lock them with the help of locking pins, and then add the pull-up bar at the top. Reverse the process to fold it back. There are four pins in total. See image below.

The assembly instructions could have been better 

That's the only major complaint people have regarding the Rep Fitness PR 4100 folding squat rack. Although the process is pretty straightforward, the instructions for attaching the rack to a self-bought wood slinger are missing, leaving you with a bit of guesswork and brainstorming. REP Fitness should include more details in the instruction booklet, especially how to install it if the floor is uneven. 

Rep Fitness should start selling metal stringers 

First thing; you can mount this rack directly on your wall. You don’t actually need stringers or wooden studs. And, Rep Fitness has provided the hardware accordingly. 

But installing it on stringers will help you enhance the overall stability of the rack. The stringers take the pressure off the wall, keeping it safe. You can buy 10” wide and 56” long wooden stingers with 2” thickness from your local hardware store. Or you may go with metal stringers from Rogue or Rep Fitness. You will also have to buy 8 M10x75 lag bolts and 8 M10 washers to attach the stringers to the wall. 

Now, we would rather spend $30-$50 more and buy these things directly from the seller instead of going to a hardware store and trying some DIY and brainstorming. It will save a lot of time and effort. Rep Fitness should seriously think about it.
