Sliding Door Handle Set, 3-15/16"

Missing parts for lock and latch on several of these doors, no visible markings on the door but photo of the top inside track of the door is only info found so far.

We need to replace the lock on the sliding glass doors as the lock is broken. Distance between holes is about 12 cm. Can you recommend the parts we need?

Would like to know what replacement handle set to order. Possible swisco part. number 82-003 3 15/16" center with 9" wood handle Replacement picture below. Thank you,

the window is a tilt in and the spring on both sides are broken. I believe I need to spring only but not sure exactly which part to order.on the sliding door the latch does not work. I think I might need a whole new handle but I again I am not sure what to order. Thanks

Hello, I have two sliding glass doors that interlock with one another. Would this be a suitable replacement if I needed to place the handles on both doors?
