Problem 1: Putting in doorstops we placed them wrong and are unsure exactly where to place them. We put them close to the door hinge after trial runs, but they don't 'lock in' and the angle is way off. Where is the best placement.
Should we put the female part closer to the front and then place the male part? We have a 4x6 aluminum sided td
Problem 2: In our efforts to pLace the door stops we created drill holes in the aluminum.

We need your expertise.....
Thanks
