Do you have these Half-Turn Locks
Hello! As a matter of fact, we have a ton of different locks that could potentially replace this. Before I recommend anything, can you tell me the distance between the two installation holes, center-to-center? That will help us narrow down the list of possible replacements.
I'm sorry, I didn't realize that you had two open discussions with us. I see now we were helping you with a weep hole cover in another thread, which seems to have evolved into help for this very same sweep lock. For the sake of organization, I will close out the information on that thread. We'll keep that one for the weep hole cover and this one for the lock to avoid any future confusion.
5.3 cms is a bit of a weird measurement for this type of lock. Converting to inches, that gives us ~2.09", which doesn't match any lock we have in our inventory. The closest would be maybe 2-1/16", which would be a little smaller. I recommend triple checking that measurement just to be safe.
Assuming it is 2-1/16", then our 90-278 is our best option. It has that same hole spacing as well as an 11/16" offset. Refer to the dimensions below.
Great! Let me know if you had any other questions and we will do our best to help.
