What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Sized for that Gibraltar clamp family. Insert diameter has to match your rack tubing or the clamp won't grip.
Detail 02
This is the sleeve inside the clamp that grips the tube. You still need the clamp body and the rack.
Detail 03
Cheap enough to buy several. Count how many clamp positions you need to cover before ordering one.
Detail 04
Inserts compress and deform with repeated tightening. Replacing them restores grip on a rack that's started slipping.

Product questions
Straight answers to the questions shoppers most often ask about this product.
One per clamp position you're servicing. Check each clamp on your rack and order to match, plus a spare or two.
Usually a worn or missing insert. The insert is what actually grips the tube, so once it deforms the clamp turns under load.
Unlikely. They're sized for Gibraltar RMAA hardware, and rack tube diameters vary between brands.
You'll need to loosen the clamp to seat the insert, so whatever key or wrench your rack hardware already uses.
