Mounting the GLS 10 Black Box Device
NOTICE
If you are mounting the device in fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
NOTE: Screws are included with the device, but they may not be suitable for the mounting surface.
Before you mount the device, you must select a mounting location, and determine what screws and other
mounting hardware are needed for the surface.
1 Place the black box device in the mounting location, and mark the location of the pilot holes.
2 Drill a pilot hole for one corner of the device.
3 Loosely fasten the device to the mounting surface with one corner, and examine the other three pilot-hole
marks.
4 Mark new pilot-hole locations if necessary, and remove the device from the mounting surface.
5 Drill the remaining pilot holes.
6 Secure the device to the mounting location.
