Attaching the lock cases
Close the door bar, put the lock cases with screw-on plate and plastic underlays underneath
according to the rebate height, hold onto the marked fitting position, align vertically in the
centre of the door bar and mark out. Close the door bar (Fig. 15).
Fitting with screw-on plates
Pay attention to the correct location of the screw-on plate: the slope of the fixing holes in
the wall must be pointed away from each door edge, when looking in the drilling direction
(Fig. 21).
1. Hold the screw-on plate onto the marked lock case position without the lock case,
pre-drill the positions for 2 screws Ø 4 x 35 mm for dowel and wood (dowel Ø 6 mm,
wood Ø 3 mm), Ø 4.2 x 22 mm for metal Ø 3.5 mm. Tighten the screw-on plate with
2 screws (Fig. 21).
2. For further reinforcement, fit wooden screws with Ø 7 x 60 mm or dowels with
Ø 10 x 120 mm:
For this purpose: bore two bevelled holes with Ø 5 mm and a depth of at least 60 mm for
the wooden screws or with Ø 10 mm and a depth of at least 140 mm through the screw-
on plate. Screw in the wooden screw or insert the complete dowel with the screw and
tighten.
3. Drill out both holes for the lock case mount: with Ø 7 mm in wood and metal, with
Ø 6 mm in stone, and a depth of at least 50 mm (Fig. 21).
4. Line the screw-on plate with defined plastic underlays and tighten the lock case with
two thread rolling screws M8 x 60 mm. If the screws M8 x 60 cannot be screwed in deep
enough, drill out a depth of 6 - 7 mm through the holes in the fastening rail. The screws
can also be shortened: Initially screw in the screw without shortening it to cut the
thread. Then unscrew the screw, shorten and tighten the lock case.

Note: If the screws cannot find a secure grip,
we recommend the use of composite mortar
from well-known brands (available from
retailers)
