Recommended tools.

• Power Drill (2800 RPM’s preferred)
• 1/8” drill bit
• Ridgid brand 1 3/8” bi-metal hole-saw part #7015, or Sears brand 1 3/8” bi-metal hole-saw part #26064. (Bi-metal hole-saw will cut through nails and screws) CRITICAL: Not all hole-saws are the same so we highly recommend Ridgid and Sears brands. If the hole-saw you are using is not one of the brands we recommend, drill a test hole in a scrap 2x4 to insure the Sure-Strike housing can be properly inserted.

AUGER, FORSTNER OR PADDLE BLADE BITS SHOULD NOT BE USED FOR THE SURE-STRIKE INSTALLATION

• Ridgid brand 3/8” shank hole-saw mandrel part #7037, or Sears brand 3/8” shank hole-saw mandrel part #26087. (This smaller mandrel is required as a normal arbor has a circumference larger than the 1 3/8” hole-saw itself)
• 5 1/2” extender that accepts the 3/8” shank of the hole saw mandrel.
• Hammer and chisel.

HARDWARE INCLUDED IN SURE-STRIKE PACKAGE:

• Sure-Strike™ unit
• Cover plate
• 3 1/2” screws (2)

CAUTION: In the rare case that less than 2” exists between the door-stop and edge of the doorjamb, there may not be sufficient area to install the Sure-Strike. The installer should measure this area and use caution before proceeding with installation.
