Used Mepla Hinge ACC 140. The action is smooth and the springs are strong. The ACC 140 hinge is commonly used in corner cabinets, lazy Susan cabinets, diagonal cabinets and cabinets with heavy doors. This hinge has been discontinued, but it's available here until they are gone. Sold in packs of one hinge. They have been ultrasonically cleaned, inspected and lubricated. I'm a cabinet maker and I've used these and similar hinges for over 40 years. Please ask if you have any questions about your application.
