dimensions of 58-164

A home owner from New Jersey says:
My vinyl window weatherstrip has almost the same side-view as the 58-164 but with slightly larger dimensions. The "T-lock" is 1/4" (not 3/8" as shown on your website diagram), the face that sits up against the bottom sash is 1/2" (not 3/8"). I am concerned that the 58-164 might be too small as a replacement - particularly the "t-lock" which at 3/8" might not hold in the channel? Is there a similar weatherstrip with my dimensions?

Good Morning,

I believe you meant to say that the "T" is 1/4" where the 58-164 is 3/16"

We currently do not have another size of the 58-164 available. I am not sure if the slightly smaller size is going to be a problem or not. Maybe, measure the channel that the "T" fits into and see if the 58-164 would even hold into your channel.
