SWISCO - The Replacement Hardware Authority

The only marking is the letter"L" on the back of the latch

A home owner from Calgary AB says:
I recently broke the lock on the dining room window and would like to replace the lock. This is the lock on the inside window. The lock on the outside window has been missing since we bought the house 22 years ago. If you sell this lock I would buy 2 left and two right locks.
Thank you

Thank you for contacting us. Can you confirm the distance between the two installation holes, measured from center-to-center? Thanks!

There is 1 1/2 " between the installation holes?

Thank you. How about our 90-021? This looks very similar, but see if you agree.

Yes it looks about right. I will order some from your website. Thank you for your help
