Justor, In is a leading company manufacturer of door accessories: door brakes, door locks and spring hinges.
Valenti Trepat christened the Range of Door Brakes by Talleres Trepat with the name Justor because they brake the right door when it closes.
In the beginning, the products only included brake models for normal doors and elevator doors.
Later, the range expanded with the pins, hinges and hydraulic door closers.
The innovation that the company brought allowed her to win the "Delta de Oro ADI-FAD" design award in 1980.
