58-059 without fin?

A quick learner from Galt says:
"Gray wool pile with a 9/32" width and a 1/8" pile height. This wool pile features a centered high fin seal in the pile."

My windows have this exact wool pile without the high fin seal. Will the high fin seal affect my windows?

It's hard to say how it will affect your window, but in a worst case scenario it would add more friction and make the window harder to open and close. You may want to consider our 58-004 instead, which has the same measurements but without the fin seal.
