These hinges are tough enough to withstand the rigors of commercial and industrial environments. Hospitals, offices, retailers, and schools all need hinges that open wider than most kitchen cabinets. Using a full overlay hinge, these will open the door a considerable 270°, giving complete access to what is in the cabinet. They use a 35mm hinge cup (MP-3011 purchased separately)and a 45/9.5mm boring pattern. These are recommended to be used on frameless cabinets with side panels of 19mm (3/4”). Grass® Institutional hinges can be adjusted +/- 2mm in height or from side to side. These zinc die cast hinges are nickel plated and the cover cap conceals the mounting screws. Purchase two mounting screws MP-5125 separately. Made in China.
