Sliding glass entrance door

[blackhawkdown]

We have a ‘77 Harbor Master houseboat whose entry sliding glass door’s lock/latch is rather worn. I can’t seem to find much information when searching for replacement latches, and other parts. I see latches for cabin doors but is that what the entry door is called? Is there a specific resource for these parts?

Have seen several sliding doors on boats, and not sure of what you need (pic might help), but have you looked at the hardware store?

I’ll have to take a few pictures. Hopefully the doors on the boat have interchangeable parts with regular doors. I’m wired to look for marine parts first. I guess it’s becuse I’m new to this and am programmed to think marine parts first. There’s so much difference to plumbing, wiring, etc. I don’t think about regular parts first.
