Hi - I can't tell from perusing your website how I should be measuring this corner key I need to replace. Attached is a picture of one dimension, it's just under 3/8" wide. There is also the height or thickness, which is 1/4". Which dimension are you referring to in your parts selection? The square end is 5/8" wide. Thanks.

I usually go by the thickness and width of the frame itself. The thickness and width of the legs are also important as a backup. I can tell you that your corner in particular looks like our 95-208. The dimensions below should confirm whether this is what you want.
