What to Compare Before Buying
- Rack compatibility: Check that your rack matches the FM-905Q Series or FM-CS7000F, and that the upright is a 2 x 2-inch tubular frame.
- Peg size: The stated peg diameter is 3/8 in or 9.5 mm, so fit depends on matching that measurement.
- Load limit: Compare the 500-pound maximum static weight capacity with the loads you expect to place on the arms.
- Length: The 16-inch length affects how far the arms project from the rack and where the bar will sit.
- Finish and padding: The powder coat finish and rubber padding are part of the product configuration and may matter if you want to protect the bar and rack finish.
What Is Included
- 2 spotter arms
The catches are sold separately from the rack, so do not assume the power rack is included.
Before You Decide
Confirm that your rack is the FM-905Q Series or FM-CS7000F, and check the 2 x 2-inch frame and 3/8 in peg size before choosing an offer. Also compare the 500-pound static capacity and 16-inch arm length with your training setup.
