This part is a corner piece to a storm door window. It allows the wondow to tilt in. The picture shows the nipple broken off. It measures 1-3/4in. X 1-1/2 in. It is a little more than 1/8 in thick.

Hello,
I'd recommend starting by comparing the 95-191 Larson corner with 1/8" thick legs to an undamaged version of your part. We also off the 95-190 with 3/16" thick legs. Keep in mind that the overall length of the legs isn't as important as the thickness. Thank you!
