I buy the correct pivot shoe for my windows. I measure the thickness correctly of 17/32" However, the width I am measuring is 1 3/16" and not 1 1/4".

Hello! Your pivot shoe has been discontinued by the manufacturer, and they replaced it with a new style: 15-046. Take a look at the measurements to see if it will work for you.
