is determined, proceed as follows:

carpet for both holes. This will prevent the carpet
from snagging or unraveling during drilling.

There are cut lines on the floor plugs. With a hacksaw
cut plugs to 1 inch.
Drill with Caution.

If not available, drill pilot hole with ¼" masonry
drill bit follow with ¾" masonry bit. Use a vacuum
to keep hole clean from dust and debree this will
help to prevent improper placement of the floor plug.
Drill ¾" holes. Drop floor plugs into holes to check
that holes are in the proper position. Check by opening
and closing door several times. When you are sure
location is correct, remove floor plugs carefully,
then apply adhesive and re-install floor plugs.
Check that floor plugs are straight, tight, and flush
with floor surface. Insert bolt into floor plugs to
insure smooth action. Allow 24 hours for adhesive

hand or a tool being forced through the opened
door and prying upwards. If Locking knob can be
lifted, tighten knob until it won't lift.
