I have tried to use my self-drilling Tek screws during installation, and they are not long enough to bite into the frame. What should I do?

The universal screw pack is equipped with a 1-3/4” sheet metal screw that will work in most instances. If a frame is filled with mortar, pre-drilling an area behind the frame with a small drill bit may be required.

I have cut my hinge to a custom length in the field and the bottom pin keeps falling out after installing the hinge. What should I do?

In this situation Markar does not recommend using the end pin. Crimping the barrel of the hinge would be the correct way to solve the problem.
