Innovative solutions for retract & slide, tilt & slide, lift & slide, slide, pivot & turn, tilt & flap

The Velbert Quality Control Association (Gütegemeinschaft Schlösser und Beschläge e.V., Velbert) publishes directives that are intended to provide assistance in the use of locks and fittings in windows and window doors and in doors. The creation of these directives is a joint effort between the Velbert Trade Association for the Locks and Fittings Industry (Fachverband der Schloss- und Beschlagindustrie e.V., Velbert) and the PIV testing institute. Whenever necessary, these two partners coordinate their activities with the Technical Committee of the VFF and ift Institute in Rosenheim.

While the use of these directives is free of charge, changing their contents in any way is prohibited!
