JUSTOR retaining brakes slow down the door just before closing it, and adjust the door tight against the frame.
The JUSTOR range contains brake models for normal doors and elevator doors as well as hinges and hydraulic door closers.
The JUSTOR spring hinges are designed using a patented operating system. While other manufacturers offer solutions based on a spiral spring, Talleres Trepat models are based on steel plates working through torsion. This innovation was awarded with the "Delta de Oro ADI-FAD" Design Award in 1980.
