What to Compare Before Buying
- Aperture size: Match the 5/8" (16 mm), 0.7" (18 mm) or 1" (26 mm) option to your rack before ordering.
- Rack width: Check whether your squat rack is 2 inch, 3 inch or 2.37 inch wide.
- Barbell bar diameter: Measure the barbell bar diameter, as this is called out as a check before purchase.
- Weight plate fit: Confirm that your plates are 1 inch or 2 inch Olympic weight plates.
- Load limit: The stated maximum load is 175 lb, so it should be compared with the intended use.
Compatibility, Size and Fit
This attachment is presented as a rack-mounted product with several size options, so fit is the main buying point. The key checks are the aperture size, the rack width and the barbell bar diameter. Those measurements should line up with your existing equipment before you choose an offer.
The stated plate fit is for 1 inch and 2 inch Olympic weight plates. That makes the exact plate setup worth confirming if you already own plates and plan to use them with this attachment.
Before You Decide
Check the aperture size, rack width and barbell bar diameter before choosing an offer. Confirm that your plates match the stated 1 inch or 2 inch Olympic format, and make sure the 175 lb load limit suits your intended use. If your rack or plates use a different size, a different version will be needed.
Planning Your Rack Setup
Because this is a bolt-on rack attachment, it works best when you measure the rack first and plan the position before fitting it. That gives you a straightforward way to check whether the attachment, the rack and the plates all belong to the same setup before you start training.
