Straight hinge with a 35 mm diameter cup that allows an opening angle of 165 ° with screw installation. It has a shock-absorbing piston that guarantees a smooth closing and an automatic coupling system to the insert by sliding. In addition, it is three-dimensionally adjustable and eccentrically, so it is possible to achieve the optimal adjustment in any case. For its installation, a separation range of 3 to 7 mm must be considered for the perforation of the cup. This hinge is made of strong and durable steel with a nickel-plated finish. It is specially designed for doors from 14 to 26 mm thick.
