This afternoon I shut the shop door going in and could not get back out. LOL A friend was on the outside and I was on the inside. We both thought the other was holding the door to fool with the other. LOL The actual door latch itself failed. The door knob will not pull it to open. Lucky that I was on the inside. I could raise the overhead door and get in or out. If I had been on the out side I would have had to cut the door hinges. No windows nor an outside door opener. I also have the hinge pins welded in. I was able to take the knob off from the inside and get the door open to remove the latch. I have a box of door latch parts left over from changing them over the years. This one is one of the longer ones and I did not have a single one that would work with the door knobs I am currently using. I want to keep the knobs as they are keyed to match several other buildings. So I will have to go to town tomorrow. So how do I keep the thieves out for tonight?????? Think this will work???? LOL
