These are TWO ROLLS of  10 mil thick sheet of Fish Paper each 12 inches wide and 24" long. Slightly more value than the original standard roll dimensions for Telecom Installations. Each roll is 288 sq. in. of light grey insulating fibroid Fish Paper. The light grey color allows for easy and more visible marking on the paper surface than its darker counterpart with the same excellent electrical insulating properties. Ideal for all Electrical Insulation. Each sheet of paper measures 12" length x 24" width x 0.01" thick and is just slightly larger than our CG560 rolls with a 12" width vs a 10" width for more coverage per sheet. This item is shipped in a roll. Slight variations in the color may occur in multiple rolls.
