Latch Hardware for up/down sliding windows?

I am looking for latches for a new up/down sliding window (bottom pane is fixed, top pane drops down). I know I have seen them used on boats before - a latch on each side of the window where you press a button to pull-back a locking pin and raise/lower the window. Any ideas where I might find something suitable?

Thanks in advance -

Thanks Russel - challenge is that because the pane of glass is up/down (vs side-to-side), was hoping for something that could be easily operated while lifting the glass - a push-button that forced a pin into a hole. Not sure it even exists. I

BTW - nice boat Russell

Window Latch Sketches - MV Weebles

Here are some crude sketches that hopefully better describe what I'm trying to accomplish. The cross-section showing push-button would be ideal --- if I can find it.

I see several pushbutton release barrel bolts on a Google search of "pushbutton barrel bolt" /images. Looks like you have to manually push the bolt in from the end, though, to set it.

Good suggestion - might work if I can't find a purpose-built window latch. Many thanks.

If you don't find one with a pin, these will work. Here is a picture of the one on our galley window. There are two installed on this window that moves up and down.Click image for larger version

This is really helpful How big is your galley window? I was thinking pure friction like this would not work well - weight of glass and some seaway would jiggle it lose. Window's on my Willard are around 30-inches wide, so not incredibly heavy, but wonder what you think give your boat has likely been through the paces a time or two

16x22. The unit has a rubber tip on it where it meets the glass. It has never came loose in some serious weather.

The simplest is the old wooden boat system where a leather belt would lift the window and catch on a pin to hold it up.

The finest I have seen was construction where the hollow PH wall was lined with copper sheeting and 3 tracks were built in.

One lifted the window glass , one lifted a bug screen , and one lifted a storm / privacy /sun shade . Any leaks would be drained to the outside deck by the copper.

Great system , but high in man hours and material cost to build.

It was still watertight and the boat was over 50-60 years old.

Another good/simple idea - I like the friction clamps that Russell uses on his 49PH, however Perko only makes them in a Zamac with what appears to be a plastic knurl, and the Sea Dog version (which appears much beefier) does not have the angled mount bracket. Workable, but this strap-with-holes idea is also excellent for a very positive support that does not depend on friction.

Thank you all so much. Really got to a much better place than where I was headed.

Peter
