Protective Tape on side of a 2720

I just realized that I am missing the protective tape on one side of the back portion of the trailer that pushes in. It is a teflon-type tape that is 2" wide (high) and about 8' long. Its purpose is to prevent scuffing of the back end of the trailer when you close it.

Any ideas what kind of tape it is, I don't see it at Lowes or Home Depot.

Thanks.
