Can't identify door part

Question

Trying to ID this part for my patio door. The only marking is on the door handle and says "K/K" on it and I believe it is a Kolbe door. The door is a inward swing type and the part is a piece of plastic that screws to the underside of the door and holds the weather stripping. It's (34.5 in x 1.5 in)

Thanks for your inquiry. See if it is possible to replace your piece with a bubble seal such as either our 58-053 or 58-114. If not, you may need to replace the complete door sweep with one similar to our 40-005.
