INTERNAL SPLICE PLATE INSTALLATION INSTRUCTIONS
Cover sections may be tightly joined with internal splice plates for a neat, trim fit. They may be used instead of external splice plates.
Step 1:
After installing support brackets on the
wall at the desired height, place the cover
over the brackets and snap in place.
Step 2:
Insert the internal splice plate just shy of
the halfway slots. Slots must remain
visable and not slide under cover.
Step 3:
Insert screws, nails or slotted screw driv-
ers into the 2 halfway slots of the internal
splice plate to hold it in the correct loca-
tion and prevent the halfway slots from
sliding under cover.
Step 4:
Place the next cover in place on support
brackets.
Step 5:
Slide the next cover over the internal
splice plate up to the screws, nails or
slotted screw drivers.
Step 6:
Remove the 2 screws, nails or screw
drivers.
Step 7:
Continue sliding cover sections together
until a snug fit is obtained.
