PR-4000 Rack Builder

The 16” depth and the 24” depth four-post racks are great space-saving options, with the ability for you to work outside the rack. The 30” deep four-post rack is the standard size and most popular. The 41” depth is spacious with plenty of working space and ideal for lifters with a decent amount of forward lean in their squats. The deeper rack adds stability to your workouts; bolt it down or add the Rear Base Stabilizer and you don’t have to. However, if you're using the Iso Arms, Spotter Arms, or Globe Pull-Up Bar, you do need to bolt your rack down, even with the Rear Base Stabilizer, regardless of your rack's depth. With those attachments, you also need to add Front Foot Extensions to keep the rack stable.

Yes, the top rear Logo Plate Crossmember is required. It serves as an anchor point for future attachments, and it also adds rigidity and side-to-side stability for the power rack. 

The PR-4000 has an impressive attachment “ecosystem”, but the PR-5000 has more attachment compatibility than any other power rack.  

The PR-4000 has laser-cut numbers every five holes making it easy to line up attachments, including J-cups and safeties. The PR-5000 has laser-cut numbers on every hole making it easy to line up attachments. 

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. 

Yes. If you add the Rear Base Stabilizer onto a 41" depth PR-4000, you don't have to. However, if you're using the Iso Arms, Spotter Arms, or Globe Pull-Up Bar, you do need to bolt your rack down, even with the Rear Base Stabilizer, regardless of your rack's depth. With those attachments, you also need to add Front Foot Extensions to keep the rack stable.

If you're using the 4-post 16” configuration, the Iso Arms, Spotter Arms, or Globe Pull-Up Bar, you do need to add Front Foot Extensions to keep the rack stable. 

No. 

Yes but be sure that your aren't placing them in the way of where your attachments would be placed. 

Yes, check it out. It's a solution for people who don't want to overthink their decision or feel overwhelmed by the Rack Builder (no judgment!).

The amount of bumper plates you can store depends on the size. You can store up to 13 45lb Competition Bumper Plates per shelf. When using 45lb REP Pinnacle Plates, you can store up to 12. When using the Black Bumper Plates, you can store up to 13. Each shelf can hold three medicine balls at a time.
