Casement Window

A quick learner from Toronto says:
I would like to know what that part is called and the purpose of it. One of my windows is missing that part and I wonder if this affects the window sealing.

I don't recognize this seal at first glance but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. Thank you!

I believe what you are showing is what is called a casement window ramp. We do carry the 67-020 ramp that screws to the bottom of the window sill. Looking at yours, it appears that your ramp "clips" into the bottom of the sill. You might still be able to use the 67-020 but you'll need to use some caulk on the screw to make sure no water gets into the window frame. 

However, are you sure you need the Ramp? If your window is in good working order then don't worry about it. My casement windows at home do not have any type of ramp at the sill. They are not the same type as your windows but if your window does open and close properly you can leave well enough alone.

Thanks for the reply. I had a hard time finding that piece. You guys have been great at figuring this out. Thank you again.

I am not sure I need a ramp. Window is working properly. I can open and close without an issue.

I will leave it alone.
