Manufacturer unknown. Only markings on door edges were hand written numbers 11 (underlined) then 276. Sweep top is dome shaped 3/16" wide and 3/8" high from top of dome to bottom. I measured the channel which is the same 3/16" wide or maybe 7/32" max.

Hi there!
Your door sweep reminds me of our 40-209 or 40-207. Look these over and see if you could use either of these as a replacement. Let us know what you think.

Can't find, looks the same as Larson40-209 except the widest point is .150 other than that it is identical. Can the Larson be trimmed?

You might want to take a look at our 58-162 as well, but the decision is ultimately yours. You can see our return policy here, just in case.
