Abus FO400N B B/DFNLI

Double security
Window handle lock instead of the window handle with adjustable steel bolt. Reliable locking windows should be a standard feature for the safety of your home. Protect your windows with this lockable additional security. The clawing steel bolts of the lock can withstand a pressure of over a ton. Since the bolts are adjustable, they can be universally mounted on aluminum, plastic, and wooden windows. The lock is installed on the window sash. It operates like a conventional window handle and serves as both a burglary deterrent and child safety device.
