The metal mounting chassis is used at both ends, which is not easy to rust and has a strong bearing capacity. ABS gas head has high wear resistance and can adapt to harsh environments. Made of the pure copper gasket, good sealing, with solid design, strong support. Round metal mounting plate, the large contact area with cabinet, three-point positioning, very formed on the upswing of the Kitchen Cabinets. Awesome!!!Could be used for many purposes. You can use it for kitchen cabinets, RV overhead cabinets doors, small tatami, wardrobes, bookcases, etc. It is so nice for you to be able to use both hands inside the cabinets without balancing the cabinet door on your head.
