Weatherstripping seal, ribbed black

A handy person from Leander Texas says:
I need some help identifying a replacement weather stripping. It has the ribbed back that slides into the door channel similar to your prime door seal set. However the profile is essentially a square tube as can be seen in the attached jpeg.

The ribbed back is 3/8inch. The tubing is 7/8 inch x 7/8 inch.

Look forward to your feedback.

Good morning, Jim.

Your weatherseal looks very similar to the header piece that comes with the 58-008 Prime Door Seal Set.
