Things you
should know
Although our products are optimized to work with all
types of doors, door alignment is extremely important
in a deadbolt install. Doors should be properly specied
and hung, and the strike should be prepped prior to
installation.
The lens and battery tray should always be paired
together. Avoid mixing the exterior and interior assemblies
with other locks on the job site.
If installing on an active construction site, it is
recommended to add painter’s tape around the exterior
of the trim where it meets the door and to leave the
protective lm on the device. Do not leave the painter’s
tape applied for longer than recommended by the
manufacturer.
The product certications depend on install in accordance
with this guide.

guide, can be found online at support.latch.com.
