I have a stripped door that has 4 internally threaded posts where a time lock once was.
The threaded posts are set in a rectangular pattern 2"wide and 1.25" high (center to center dimensions).
The cover plate that the time lock would frame the time lock has an opening 4"wide and 3.75"high.
Seems like a smallish timer compared to others I have seen.
Anybody want to guess what time lock was installed there once upon a time?
