The housing of the BURG-WÄCHTER window security WinSafe WS 44 is made of solid zinc die-cast and is VdS-approved and ECB•S-certified for installation on wooden, aluminum, and plastic windows with metal inserts. The WinSafe WS 44 is suitable for inward-opening windows and window doors with a rebate thickness from 3 to a maximum of 31 mm. The operation is particularly convenient due to the sliding mechanism. Another advantage is that you can always tell whether the lock is in the locked position, eliminating the need for tedious checks. The WS 44 is designed to secure the hinge sides of your windows and window doors, providing maximum resistance against attempts at forced entry. With just a few simple steps, the mechanical lock can be quickly installed. You can start the installation immediately, as the assembly of the individual parts has already been completed.
