this part is from the side track of a storm window. Same storm window that has what appears to be the Sears Tilt Pivot (your Product Code: 95-182) at top corners. Length: 3/4", Width 7/32"

Thank you for submitting your inquiry to our discussion board.
Take a look at our 95-183, compare the dimensions to what you have, and see if this isn't a better option for you.
