We LOVE these rings as an alternative to a welded ring or standard keychain for your bow perch or shelf perch setup. They're light, removable and quiet.
 
We include one 4" ring (1.5" diameter) for retrofitting onto tight shelf perch setups and one 6" ring (2.25" diameter) perfect for bow perches and larger shelf perch setups. Also included is a piece of black shrink wrap to seal your ring once installed. Simply cut to size and use a heat gun or lighter to seal.
 
We've now tested these rings and completely switched to them for our shelf perch setups, and Matt Mullenix has had success with them on the bow perch setup. Give one a try. We doubt you'll go back!
