Note that this is for the Screen Protector only and does not include the latch which is sold separately by me.

This is a 3D printed replacement for the hard to find Pella sliding screen protector - right side. It's 3.875 inch long and 0.5625 wide. I find that this 3D printed protector to be stronger than the Pella original protector. This is printed with a solid infill. When installing take extra care not to tighten the screw holding the screen protector too tight eliminating the possibility of cracking the screen protector.
