This Fish Paper Roll has limited stock and typically a special order with a lead time. One (1) inch wider and 50% thicker (0.015") than our popular 5" width x 0.010" roll and used for specific jobs for a slightly faster application. The extra thickness make for a more sturdy final installation for more rugged edges and corners. The 6" wide rolls are still convenient to carry, manage and install but the extra thickness comes with some extra weight. These Fish Paper Rolls are continuous with no joins. These rolls are 15 mil thick, 6 inches wide and 50 feet long.
