MORTISE CYLINDER

WHEN USING POWER TOOLS

Installing an inside cylinder on an existing mortise lock can be
frustrating to center correctly. The HIT-21 will make the job fast, accurate
and easy. You don’t even have to take the mortise lock out of the door.
Just remove the outside cylinder, thread the HIT-21 into the mortise case
until it contacts the mortise cavity on the opposite side. Next drill a pilot
hole then come from the outside in with a hole saw. Nothing could be
easier!

These are the most important tools that you

will use in this installation.

Always use
eye and ear
