Attention
1. Choose a proper installation kit based on the door thickness;
2. The default tool kit is applicable to doors of 38-60mm thick. If your door thickness is out of this
range, please contact us.
Installation steps
The following installation steps apply to right-open doors. For left-open doors,
please read the chapter [Pre-installation instructions] carefully and make
needed adjustments.
Use the drilling template to drill

the needed holes on the door and
mount the mortise into the door.

when the mortise is inserted.
(This step is unneeded when
installing wooden doors.)

Tighten the 4 anchor screws on
the mortise.
Pass the cable through the hole

on the door. The mechanical key
tailpiece needs to be inserted
into the two rotary holes on
the mortise, so that the outer
escutcheon stays close to the
outside door.

Install the connecting screw tubes
and mechanical key tailpiece on the
outer escutcheon, and insert the
compressed spring and square shaft
into the handle hole (the compressed
spring faces the handle side).

shall
be
appropriately cut as per the thickness of
the door, and the square shaft, connecting
screw tube and anchor screw tube with the
appropriate length shall also be used.
Tighten the mounting plate with an

anchor screw against the inside of
the door.
