The Peep Reducer can be used with the 749-42LH and 753 Peep Housing to reduce the hole size to 3/16" opening so 1/8" apertures, clarifiers, and verifiers can be screwed into the 1/4" housing. We recommend you use the 210078 dual aperture wrench to install the reducer into your peep.
CAUTION: High powered bows create a great amount of vibration. This may loosen verifiers, clarifiers and apertures over time. Tighten your apertures before each use. If you hear a buzzing sound, this indicates a loose aperture. You may use a drop of the blue Loctite or Vibra-Tite VC 3 to help hold the apertures in place.
