It’s designed to work with doors that have a minimum thickness of 1-1/2″ (38 mm) or more and offers a 125° opening angle. To ensure the longevity of the hinges and the door, a door stopper is recommended. These hinges have proven their durability, having successfully passed 300,000 open/close cycles. Their compact design, combined with an exceptionally straightforward installation process, makes them an excellent choice. Plus, they provide adjustability with ±1/8″ (3 mm) in depth, ±1/8″ (3 mm) vertically, and ±1/16″ (1 mm) horizontally when used with a spacer.
