The Corner Locking Pivot Shoe was the recommended replacement for my tilt window. After doing a cut out, I was able to correctly install the shoe and attach it to the channel. It worked great. On the other side of the window, this shoe would not fit even with a wider cut out area. I wedged it in, but then it would not slide freely.
It seems the black locking piece is the problem - it sticks against the side.
Is there a substitute I can use that doesn't have that black piece?
thanks.
