Profiles with thermal separation
At tention!
Lack of finishing can lead to product malfunction: When using profiles with thermal separation, the
components listed below must be finished with additional work.
Aluminium stop edges can lead to destruction: Aluminium abrasion can destroy the lock or strike plate.
Finishing profile webs
When closing the door, the latch and trip latch must slide over a flat surface (“Self-locking function”,
page 45). Some door frames, such as those with thermal separation, may feature a profile web that
interferes with the sliding surface. This profile web must be removed in the area of the latch and trip latch.
ASSA ABLOY Sicherheitstechnik GmbH recommends using a strike plate with a tab aperture to create a flat
sliding surface
1 Cover existing profile grooves or other uneven areas.
2 Remove the webs. The profile web in the latch area must be removed down to the mounting level.
3 When closing the door, check whether the latch and trip latch can slide unhindered over a flat surface
into the closing position.

The profile webs are smooth and the locking function is guaranteed.
