Pile weatherstripping

A quick learner from 46375 says:
I'm having some trouble finding the right size weatherstripping for the gap between my double doors. I ordered your part number 58-045 but the backing strip is too wide. I measured the original strip and it is approximately .15 inches using a caliper or 3.9 mm and the length of the pile isn't critical, at approximately .28 inches my confusion is in the 2 different size listing of the items shown, which number represents width and height?
Are there any recommendations? The color needs to be gray or dark. White would stick out.

The first number is the size of the base, the second number is the height of the pile. The pictures on each wool pile's shop page show this; for an example, I've reproduced the picture of the 58-045 dimensions below. 

We don't have any wool pile with a 3/20" base, so please double-check that base dimension. Let me know if you have further questions.
