3.2 P-400 Gibraltar Reader Mounting Instructions
There are two methods for mounting the Gibraltar Reader on a solid metal surface (see
Figure 2:).
1. To mount the reader from the outside, three holes need to be drilled. One through-hole
(3/4" - 19 mm) accommodates the reader cable. Two holes correspond with two 1/4",
countersunk through-holes in the face of the reader (hole size is dependent upon the
size of the mounting screw).
2. To mount the reader from the inside, five holes need to be drilled. One through hole
(3/4" - 19 mm) accommodates the reader cable. Four 1/4" through holes correspond
with four 1/4" x 20 tapped holes in the back of the reader. Drill these holes to
accommodate 4 - 1/4" x 20 bolts.
