ABUS FOS650 Window Additional Fuse This ABUS window lock reinforces windows with a long clawing steel latch. Two additional securing points are created on the window frame in addition to the conventional lock on the handle. Thanks to the 3-point lock, the window can withstand pressure loads of over one tonne. This means that you are also against powerful burglary methods such as Lever attacks. Thanks to the slim design, the window lock takes up little space during installation - ideal when space is scarce.
