Ellison window series 1500 shoe replacement

Hey there! Thanks for reaching out to us. I'm afraid the pivot shoe is too obscured when it's installed. Can you remove yours and show us a few photos? We'd also like to know the written-out thickness and width.

Thank you for the additional photo! I'm sorry to say that your old pivot shoe is discontinued and we don't have an exact match. The 15-086 tandem coil housing looks similar though. This is used with the S180 coil springs and 15-087 pivot shoe. Another thought is the Series 161 assembly. Note that you would need to purchase the 26-083 pivot bar as well for both options. We can't make any promises since they aren't exact matches but review the specifications and see what you think.
