Installation Guide

  1. Drill a hole into the base material to a depth of at least 1/4'' (Deeper than installation anchor depth).
  2. Clean hole using a dust blower or compressed air.
  3. Insert the anchor through the fixture into the anchor hole. Tighten the anchor by rotating clockwise and applying pressure towards the base material.
  4. Continue tightening the anchor until the head is firmly seated against the fixture.

Note: In extremely dense materials, use of an impact wrench is recommended.
