WMB 817 / 818 Locking Actuator

Compact 24 VDC locking actuator, which automatically locks/opens the espagnolette system on the window, in such a way that the CE approval of the window is maintained. This unit can also be used for increased protection against weather or break in.

The locking actuator is fitted on windows with an espagnolette system without handles, together with electric window actuators with MotorLink®. The locking actuator can be surface mounted on or concealed in aluminium, timber or plastic window frames. The espagnolette system can be set in two positions: locked/open.
