No idea what these are....

Question

These small plastic parts are on either side of the window frame of what I believe are PGT single-hung windows. Several have broken off. Can you tell me what they are and if they are necessary? If so, can they be replaced? Thank you for your help. Photo is of front and back of one of the plastic pieces which appeared to snap in. They are now quite brittle.

Hello!

This part is called a face guide and its purpose is to stabilize the sash by helping keep it in place. It's basically meant to prevent any wobble or sudden movement. And they are replaceable, yes!

We have the 67-014 which is smaller than the original PGT guide but we've found it works well for the PGT windows. Look over the specifications and see what you think.

When it comes to the installation, I recommend you use two flat-blade screwdrivers and slide an inch into the gap so as to pry the frame away from the window without leaving visible scratches.
