Storm door sweep. How to find right one.

A handy person from Maryland says:

Hello,

I ordered your Larson storm door sweep. Item # 40-207. It looks very similar to one I removed from door. But it is either slightly too large or I am trying to install incorrectly. It is the 'T' style that is supposed to slide in a tiny track on bottom of door.

Can you tell me is there a way to identify my door brand? If I know that I should be able to find exact match. I don't know if it is a Larson.

Thank you.
Tom.

It's possible you have something different from the 40-207. There are a bunch of sweeps with a "T" shape. At the end of the day, it comes down to size. How do the dimensions of our 40-207 compare to your original sample? Can we see a clear picture of your original sweep? We will need to see its end profile, just like how we show the 40-207 on our site.
