Hello,

I need a keeper for my vinyl sliding glass door mortise type latch. I don't know the manufacturer of the handle.

Thanks for your help.

It's a bit tough to make out your mortise lock in these photos, but it looks a bit like our 82-218. This mortise lock can work with a number of different keepers, such as the 89-021, 89-021D, 89-029 or 89-041. See if you think one of these might work for your door frame.
