These measurements were made with a t-square, I did the best I could.
length- 2 1/16 to the pivot pt. 2" side tip to side tip
width 1 1/4"
depth 1/2'
If you need a picture installed, I can send that later.
on the inside I think I see the numbers 4610108 ?
That is a patent number. I think 15-35 1/2 " thick will work. I saw it in another discussion.
