......trouble in studio build paradise.......
I ordered 14 ball-catch assemblies on eBay for a couple bucks each (locally they were $10 a piece)!
I had planned to put at least 2 on each door that didn't have a typical handle/latch ( one door at each entry/exit had to have a lock on it and thus a typical handle).
I put two on the main entrance door and I am not happy with they're ability to latch the door tight against the weatherstripping. First of all I need to point out that I had VERY large gaps at some points on the two exit doors between the jam/stop and door. This might have been because the jams were just standard pine and were exposed to the elements for quite some time after being installed (a couple months I think). I'm quite sure that they warped at least a bit.
Because of this I had to use two different types of seals on the jams (two different thickness) as the pic shows. And because of this the door requires a pretty good amount of force to keep it pressed tight against the weatherstripping. The doors with the standard handle and lock (and hole through the door) work great - I was able to get a nice tight seal on both of them, but these ball catches just don't seem up for the job. I think even if I added a third it wouldn't make a difference.
I'm seriously considering boring a hole in these two doors and installing a standard handle and latch....

But before I do that I'm going to try to add a wedge along the stop portion of the jam underneath the weatherstripping in the places that aren't sealing (sort of as pictured).
By the way - the latches are aligned properly although it did take some time for me to get them that way.
Having to use the two types of seals and wedging the the jam/stop like this really feels very unprofessional - and that has me really frustrated!
I did some sound testing and measurement and based on that I actually think I would be happy with the results if both doors had holes bored through them. I stuff the door handle cavity as full with insulation as I can while still allowing the handle to function properly.
