We purchased a stainless steel hinge from McMaster-Carr and installed it on the box after receiving the corrected tray. We chose not to get the hinge with premade holes as we will decide where the holes and bolts should be when we position the hinge.
The hinge can be cut with a miter box and a saw. We made it the entire length of the box to ensure that we had as much surface area to work with for attaching the hinge to both the lid and the base of the box. Holes and bolts will be added later to create a mechanical connection
We drilled 2 holes through the top and bottom of the hinge and adhered them mechanically with bolts and nuts. The bols on the bottom are hidden by the tray.
