PR-4100 Folding Squat Rack

You will need eight (8) M10x75 lag bolts and eight (8) M10 washers to mount the wooden stringers to the wall. Then use the eight (8) M16x80 bolts and eight (8) M16 washers to mount the brackets to the wooden stringer. To mount to a concrete wall, use the M10x90 expansion bolts provided in the hardware pack.

The rack does not come with a stringer. Your local hardware store should have a wood stringer available.  

The “stringer” is the wood mounted onto the wall/studs that you affix the rack to. Create a stringer using two wooden pieces with the following dimensions: 2x10x56”. We also suggest eight (8) lag bolts and washers, M10x1.50, L75 to securely mount the stringers on studs.  

Yes. Although there is minimal vertical play in the hinges, we recommend mounting the rack fully assembled in the folded position to ensure it doesn’t get stuck while folding it back in. Vice versa, you may want to start assembling it in the open position. Using a couple of ¼ shims under the uprights during assembly can help.  

Technically yes, but we do not recommend using this attachment, as it could possibly lead to wall damage. The spacing of the brackets on the PR-4100 also limits the functional range of the ISO Arms .

7-8" with the bracket being 9.5” off the ground for optimal stability.  

Yes, but we recommend the 41” depth option for people performing kipping pull-ups or muscle-ups because of the body movement (out/back or in/out). The built-in pull-up bar is 1.25”. 

Yes. If you purchase the spotter arms, it is important to make sure the rack is properly secured into your wall, as the weight on the arms could possibly cause separation from the wall if the rack is not properly mounted.  

No, the PR-4100 is not compatible with REP's Stringer.

Many attachments are available now and more are in development. A rack’s attachment ecosystem is one of the biggest reasons why you would choose one versus another. When you purchase a power rack, you’re buying into the company’s ability to come out with new attachments that add additional functionality over the life of your power rack. Our engineering team is hard at work developing new attachments every year, and we believe this is one of our biggest differentiators.

Here's a look at how REP equipment compares with others on the market. Plus, here are some things to consider when comparing power racks.
