Hello, i'm trying to understand which T seal for my window is the best. I'm not familiar with the measurement terms, so I included pictures of the measurements. Thank you

Thanks for your post! The T-slot seal you have here can be replaced with the 58-171, 58-182, or 58-183 foam weather seals. To determine which of these might be the best fit, be sure to compare each of their dimensions.
The 58-182 and 58-183 have the same dimensions, the foam is just hollow for the 58-183.
