The X91N double door hinge is designed to be used on corner double doors, allowing both doors to be opened at the same time.. It does not have a damping piston, so it is advisable to install it together with magnetic closures. It allows a three-dimensional and depth adjustment by means of eccentric, guaranteeing a perfect final arrangement. In addition, it has an automatic mechanism for coupling to the supplement. It can be used on doors from 14 to 26 mm thick. It is made of nickel-plated steel with great resistance and durability. The edge clearance for drilling the 35mm cup is 3 to 7mm.
