Hey Kendra, you would want to measure from the back of the lock face to the base of the threaded body and the diameter of the hole that the latch fits into to pick out a replacement. If you can get me that info I can see what you'd need. The part # RD28MR that you referenced is 7/8 inch long and fits a diameter hole of 3/4 inch.

Hi Jameson, Thanks for the clarification. We measured from the back of the lock plate to the base of the threads, and had to return what we'd ordered, as that was only 5/8". Measuring to the base of the thread BODY we come up with 7/8th". Have a great long weekend! Kendra
