Searching for .375 T-slot Foam Filled Bulb weatherseal

A quick learner says:
I am trying to find what appears to be .375 T-slot, foam filled bulb weatherseal for a replacement window. The seal attaches at the bottom of the bottom pane, facing the outside. I measure the bulb as 3/8 inch (though it is quite smashed). The base extension (with the T) is also 3/8 inch (or one cm) and the T is about .5 cm wide. There is another extension (no T) on the opposite side of the bulb that is about 1/8 inch. I have attached photos of the strip attached to the window, as well as a cross section. Thanks!

We unfortunately don't sell anything in the exact dimensions you've given. I would say the best two options we have are the 58-171 and 58-182. One of these may work for you, but I highly recommend that you triple check the size of the "T" to confirm.

Please note that all of our dimensions are in inches, not centimeters.
