4 inch wide duct tape partial roll

Partial roll of 4 inch wide Polyken silver gray duct tape. The roll measures 5 1/2 inches outside diameter and probably has over 100 feet of tape remaining. The full roll of Polyken tape is advertised at 55 yards and has a list price of $45.57 per roll. This roll is at least half and probably closer to three fourths of a roll remaining. This was part of a lot from an auction and I have no need of a roll this wide. The majority of Polyken tape is 12 mil thick which would make the length of this partial roll over 115 feet. If it was thinner than 12 mil the length would be more.
