Lever lock for rear slider.

Hi there!

This is a bit odd. Your lock resembles one of our casement multi-points like our 38-095, 38-096, 38-138 or 38-139. However, these are designed for casement windows; not doors. Can you remove yours from the door and show us?

As for the curtain rod, I'm afraid we don't have much experience with curtain hardware. That's a bit outside of our purview. Generally, there are some type of screw(s) that hold it in place that you should be able to remove.
