Thanks for posting on our Discussion Board. I believe you may have our 15-134 pivot lock shoe that goes along with our Series 900 spiral balance. IN order to compare the measurements between both pivot shoes, you will need to remove the shoe from the window. I have placed some helpful videos on this page of different methods of going about it if the manufacturer did not make cut outs in the window track for it. |
