The only ID on our screen/storm door is "LGR" on the pneumatic door closer. The original lock of this outward-swinging door can be locked from the inside only.
We'd like to replace the original lock or find some kind of screen door key-locking deadbolt or keyable push button latch to add that would allow us to lock the door from both the inside and outside. However the width of the screen/storm door is only 3/4", and within the groove, the width is only 1/2". Any suggestions are welcome. Thank you.
