Why dont you use a traditional two-piece piano hinge on PAINT PORTER?
During prototype testing we found that the two-piece piano hinge had a tendency to get coated with paint and loose its flex-ability. So, we tested the living hinge to see if it could provide a satisfactory replacement. We were willing to compromise some in the durability of the hinge to insure function, but to our surprise the living hinge far exceeded our expectations. After over five thousand flexes and numerous applications of shear stress that far exceeded the stresses experienced in the real world, we could not get the hinge to fail. The Sta-Klean living hinge is guaranteed against failure.
