tips for Drilling the fence
All you have to be is close. Close enough that
is to bend the fence towards the center of the
drilled hole. With this accomplished, there are
a couple of ways to eliminate the fence. You
could try drilling it off freehand, use a hole saw
to remove that portion of the lever holding the
fence or use the Fence Drilling Jig provided
with the 8400/8500 Drill Guide. The Fence
Drilling Jig has 2 parts, the tube with knurled
brass handle and 6” extension drill and the 2
parts together.
The Fence Drilling Jig is designed to aid the safe technician in removing the fence
on combination locks whose fence is coming towards you as it is on some Sargent &
Greenleaf, LaGard and Ilco locks. The drilled hole size cannot be less than 1/4” and the
depth from the face of the safe to the lever shoudl not exceed 3-1/2”. It is not ciritical for
the drilled hole to be centered on the fence. If your drilled hole is off center, use an ice
pick or similar tool to bend the fence towards the center of the drilled hole. To use, insert
the drill into your hand held drill motor. Insert the tube into the drilled hole of the safe.
While twisting the tube back and forth, slide the tube onto the fence allowing it to bottom
out on the lever. Hold the tube firmly, insert the drill into the tube, turn on the drill motor
and carefully drill away the fence. The depth required to completely remove the fence
from the lever is 5/8” for a 3 wheel lock. For a 4 wheel lock, the depth required is 3/4”.
