Here goes;
The bolt hooks in the top of the door and is held in place with a lock nut. The bolt threads then screw into the center hole of the trolley that rides along the track on the door frame. When the door opens the trolley slides along the track, allowing the bolt inside the center hole to turn slightly allowing the door to do it's unique pivot action.
If I put loctite on the threads, how is the door supposed to piviot open if both ends of the bolt are held in place?
Part 2 of this mystery is the unscrewing itself. If the bolt is threaded into the trolley and turns when the door is opening (loosen) wouldn't it turn back when the door is closed (tighten)? How does the bold come unscrewed?  There must be some 4th dimension the door travels through.
Anyway, I'll try the loctite and see if that helps. I like the door itsef, but this trolley/bolt setup could use a redesign. |
The other fix I am thinking about if this loosens up again it to use a left hand threaded bolt.The problem is once it loosens it creates a space & will not tighten on its own, thats were a left hand threaded set up would work.
