Note!
With tilt sashes, the clearance between frame and sash profile
must be at least 1 mm in order to provide for safe closing of the
window. If frame and sash profiles are flush, or if the sash profile
stands back from the frame profile on the interior side, it is nec-
essary to underlay the tilt sash bracket accordingly.

Note!
With the formulae indicated below it is possible to determine the approximate force required to
open or close a (smooth-running) window;
Possible snow loads are to be considered.

The application formula considers tilt and top hung windows only. The maximum rated drive
force is to be taken from the technical data you will find in section „2“. If the values you calcu-
lated exceed the max. allowed force, please contact Gretsch-Unitas GmbH Baubeschläge.
