These handles were designed for ease of installation, lay-flat form factor, and magnetic coupling. Two wood screws (or machine screws) on each end of the pivot points prevent axis misalignment. The pivots are comprised of a 1" no 6. machine screw and a corresponding #6 nylock nut.
Depending on your application, an additional latch may be necessary to keep the two surfaces tight together.
