Leg dimensions for the 95-229?

Your 95-229 looks like it might be the correct key but it doesn't give the dimensions for the legs that slide into the screen frame.mine are 1/2" x 3/8" x 1" long leg. Could you tell me if the 229 is a match? The only marking on the key itself is a 3. Thank you

The 95-229 corner was a perfect fit for the cracking screen corners on our awning style Windsor Windows that are wood inside and aluminum clad outside. The etching on the window glass corner identifies the Windsor Windows and has several possible date code numbers. The fin on the Swisco corner legs fits into the offset groove in the screen frame and should provide additional strength. The visible part of the corners measure 3/4" square and 7/16" thick. If the screen is to be reused remove the spline and screen on the short sides, replace corners on short frames, push back onto long frames and roll spline back in.
