Big Horn 70140 Reducer Ring, Standard 2-1/8 Inch to 1-1/2 Inch Reduction

This standard reducer ring will reduce the hole opening in the back plate down from 2-1/8" to 1-1/2" when using the 1-1/2" bit for deadbolts. The back plate prevents splintering of the door face when drilling the cross-bore hole. Replaces Templaco RR-700.
