Your picture doesn't show the inside dimensions of the leg of the corner going in to the frame.The one I am looking to replace has the flange at appx. 17/32 with the inside at 3/8.

Hm... this looks familiar, but I can't read the dimensions in your photos well enough to tell. Take a look at our 95-262. The legs are 3/16" thick and 1/2" tall. Is this what you need?
