Cage Arms

This is the bubble’s first contact!

Teflon rollers wearing lead to marking, pinching, and tearing of the bubble. It is common to see in most applications a bubble is backed off from the rollers, but this prevents you from getting the benefit you paid for.Pearl offers exact retrofits to upgrade your existing cage with our SM24 “Extreme Slip” surface technology.
