Balancer shoe

Thanks for reaching out! Your pivot shoe looks like it could possibly be either our 15-178 or our 15-188. Although, to confirm which of these is the right replacement, you'll need to remove the shoe from the window to compare the dimensions and design. Take a look at the diagrams below for reference.
