No, this is not compatible with the Ares but is compatible with the Lat Pulldown & Low Row attachment.

Yes. 

Yes but if you purchase the 16" crossmember depth and a Lat Pulldown and Low Row, the Multi-Grip Pull-Up Bar is not compatible.

No.

The Omni™ has a flat foot base that stabilizes the rack when doing dynamic movements, so you don't need to bolt it down to the floor. 

With the PR-5000, if you add the Rear Base Stabilizer onto a 41" depth configuration, you don't have to bolt your rack down. However, if you're using the Iso Arms, Spotter Arms, or Globe Grip 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. 

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. 

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. 

The amount of bumper plates you can store depends on the size. You can store up to 18 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. With slam balls you can store up to four REP 5-30lb Slam Balls or three REP 35-70lb Slam Balls per 41” shelf.

You can fit pairs of 5lb-20lb, 25lb-35lb, 40lb-50lb, 55lb-65lb, 70lb-75lb, 80lb-85lb, 90-95lb, or 95-100lb dumbbells on a single 41” shelf. You can fit a full set of our 5-50lb dumbbells on three 41” dumbbell shelves. Rubber Coated Dumbbells are not compatible.

Each shelf has a usable area of 3.13 square feet.  It will depend on the size of the kettlebells, and the orientation you choose to store them (single or staggered).  You can stagger pairs of 8kg-18kg(6 pairs), pairs of 10kg-20kg(6 pairs), pairs of 16kg-22kg(4 pairs), pairs of 20kg-24kg(3 pairs), pairs of 22-28kg(3 pairs), pairs of 24-32kg(3 pairs), pairs of 36kg-40kg(2 pairs), or pairs of 44kg-48kg(2 Pairs) of Kettlebells (kg) on a single shelf.   

The Dumbbell Storage Shelf, Kettlebell Storage Shelf, and Ball & Plate Storage Shelf have a weight capacity of 600lbs.

We do not recommend installing them any higher than 60”. 

The 41" shelves plus additional upright will add 46" in width per side. 

The shelves will add 5.4" to the depth of the rack.
