The solid construction of the Pro-Lok Killer Jig makes it a versatile cylindrical/tubular lock installation kit.

Drill Bits - Three heavy-duty drill bits are included in the kit. The one-inch auger bit is used to drill the edge-bore hole for most deadbolts and latches on wood doors. The same bit can be used to drill the hole in wood frames to accept the deadbolt or latch. The one and one half inch multi spur bit is used to bore for some deadbolts and the two and one eighth multi spur bit is used for most knobs and levers and some heavy duty commercial deadbolts.

Carrying Case - The entire range of tools is shipped in a sturdy custom molded carrying case with a polyurafoam interior to protect the contents. Pre-cut areas hold each component in place during transport and keep the tools from contacting one another. (Photo 12)


Step 1. Select and install the proper size bushing plates and set the backset knob.

Step 2. Place the jig on the door at the desired height.

Step 3. Adjust the door thickness knob to match the door. Use the clamping knob to tighten the jig into position. The jig body must be tight and flush with the face of the door. If the jig is not flat against the face of the door, damage or injury could result. Finally the door thickness knob is checked and adjusted if necessary.

Step 4. Position the quick-change adapter in the drill chuck and tighten.

Step 5. Insert the appropriate multi spur bit to match the cross bore size.

Step 6. Position the multi spur bit in the bushing plate, drilling the hole on the face of the door through to the halfway point. Remove and reposition the bit in the bushing plate on the other side of the door. Drill the hole completely through the door.

Step 7. Release the spur bit from the adapter and replace it with the one-inch auger bit.

Step 8. Drill the one-inch edge bore hole to the proper depth. Remove the bit and remove the jig from the door.

Step 9. Use the correct latch marker to match the lock faceplate. Rap the latch marker with a hammer, then use a sharp chisel to mortise out the wood from the marked area.

Step 10. Insert the strike locator into the latch hole with the sharp point toward the door edge. Close the door tightly and push the strike locator firmly to mark the strike center location.

Step 11. Use the one-inch auger bit to drill the latch/bolt hole to the proper depth.

Step 12. Select the strike marker to match your strike plate, rap with a hammer to mark the outline and chisel out the area indicated.

Step 13. Install the hardware provided by the hardware manufacturer.
