  2. The depth of the hole can be deeper or equal to the minimum embedment depth of 2-1/2″ which is equal to the length of the anchor . 
  3. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb. 
  4. Insert the anchor with its threaded end first into the hole. 
  5. Place the fixture over the 1/2″ Double Expansion Anchor, insert a 1/2″ diameter bolt through the fixture and into the 1/2″ Double Expansion Anchor.
