Alpine window lock

The keeper is different than most as the tab sticks out instead of pointing downward. on the back of the keeper it looks like there is a 2 on one side, then on the other is 8193

The lock has the name Alpine on the front, holes seem to be about 2 1/4" apart and set back about 3/8" on the back is the number 8300-00. Thank you for your help!

See our 90-180 Sash Lock and 90-183 Keeper. Double-check your dimensions and see if this lock & keeper could work for you.

Hi I am also looking for the same locking system for my windows as posted above by "A home owner from Anchorage, Alaska"; the one replied in the thread doesnot work for me. Do you guys have the same one as posted in the question ?

I'm sorry to hear that Bob's suggestions didn't work out. Can you go into more detail as to why they failed? If it's a matter of size difference, can you give me your exact dimensions as compared to the 90-180? Right now that looks to be our best match, so if that is not a good replacement we need to know why so that we can find something better.

The Alpine locks in question have the keeper opening in line with the screw holes. The 90-183 has the keeper opening rotated 90 degrees by comparison.

The size is fine, but the way these windows are set up that model keeper will prevent the lock from being able to close.

I see what you mean. What you're describing is called a face-mount keeper. The only such keeper we sell is the 90-282. Look this over and see if it would fit in the space available. It would be compatible with the 90-180 lock.

I missed the reply from some months ago. I ordered the suggested lock (90-180) and face mount keeper (90-282) and both fit nicely. Just wanted to follow up to confirm for the thread that they are a drop-in replacement.

Here's an image (sorry for the flash; not great lighting at that window) to show an original and a replacement side-by-side.

Thank you!

I just ordered 3 sets. I'm glad I found these and the fit was confirmed by a previous searcher.

I have the Alpine windows in my house and was unable to find replacement keepers, or sash locks for them.
I'm very happy I found this Swisco Q/A forum with positive feedback on fitment. I ordered 3 sash lock and 3 recessed keepers. Perfect fit. Do not be over zealous when tightening the screws, if you strip one they are a #6 size screw. I picked up a #8 stainless steel screw set at the local hardware store and it fit the recessed keeper for a solid lock.
Thank you for carrying these hard to find items.
