Looking for tilt window parts

Hello,

We can't be sure with your part still installed but the 17/32" deep 15-199 pivot shoe would be a good place to start. Also, see the 26-378 pivot bar commonly used with the 15-199. Review the specifications of both parts to confirm they match your original hardware. Thank you!

If there is no cutout in the jamb liner to remove the pivot shoe, see the video below showing how to make one.
