Weatherstripping for sliding door

I'm afraid I don't recognize this wool pile. The base is a little peculiar. has it been damaged in some way, or is this it? How does it install in the door? I'm not sure if we have a match for this as I see it now, but we can certainly look into it after a little more information.

Ah, I was afraid that might be the case. I'm afraid this is not a style of wool pile that we're able to supply. We did carry this at one time, actually, but it was discontinued and our stock ran out not long after. I'm afraid we will not be able to provide a replacement option for you. I apologize for the inconvenience.
