Pivot Shoe
Thanks in advanced,

Hi Steve, thanks for writing in. I recommend you take your pivot shoes out of the window in order to get the most accurate measurements. It's difficult to make an identification with the shoe still in the window. The most important dimensions are the width and depth - you don't need to worry about the height.
If the dimensions don't match up then it likely will not work, regardless of the patent number. You don't need to worry about the color of the cam though. The width and depth are the important components. I highly recommend you take the pivot shoe out of the window to get accurate dimensions. This way we can ensure you receive the correct replacement part the first time around.
