The angle support arm is synonymous with strength and solidity; an assembly without compromise. The focus of this hardware is on functionality and basic design. The fastening elements are as invisible as the auxiliary elements: door stops and glass panel retainers. Both functions are integrated into the support rail and hidden from view. The b.900 system is designed to be noticed - the new polyamide roller track is the eye-catcher. The deliberately selected material is also characterized by strength and durability. Precision bearings ensure smooth and smooth running.
