How to install
Hollow set Drop in Anchors in hollow cinder block walls:

(Don't worry, it's super easy.)
Hollow set Drop In Anchors

    Items you'll need:
  • Power drill
  • 5/8" masonry drill bit
  • 3/8"-16 Hollow set drop in anchors
  • Hammer
  • 3/8" Socket head bolt
  • 3/8" set tool
  • 5/16" hex wrench
Drill using 5/8 inch Masonry bit
Step one, Drill the holes:
Using your drill and the 5/8" masonry drill bit, drill a hole in the cinder block wall.

Step two,
Insert the hollow-set drop in anchor as shown. Use the hammer to tap it into place. It should be a fairly tight fit.




Step three,
Countersink the anchor:
This can be done easily by turning your socket head bolt upside down and placing it on the anchor. Tap it with the hammer until the front of the concrete anchor is about 3/8 of an inch below the surface of the concrete.

Set the Anchors
Step four, Setting the anchor:
Place set tool on the socket head bolt and fasten the bolt to the drop in anchor. Using the 5/16" hex wrench, turn the bolt until it feels nice and tight. Keep turning almost until i feels like it won't turn anymore. This will pull the back of the anchor toward the the front of the anchor. As it gets pulled in it will expand the anchor which will put pressure on the surrounding concrete keeping it in place. Remove your bolt. When it is properly in place the anchor shoud still be countersunk about 1/8 of an inch.

Fasten Climbing Holds
Now your cinder block wall is ready for climbing holds!
(Well, at least one anyway!) Be careful not to over-tighten the bolt when you are fastening the hold. If you put too much pressure, you can pull the entire anchor toward the hold. If this happens you'll need to take the hold off, screw the bolt into the anchor, tap the anchor back into place and repeat step 4.
