Need a tool for marking straight lines around pipe, or, for use as a straight edge? Here it is; it's inexpensive too. It is made of flexible gasket material and has a good resistance to heat and cold. **Grey** Note: All Wrap-A-Rounds are available in two colors. These designate material type and service temperature. *GG (Gray) material is used for high temperature applications up to 550 degrees F. *B (Black) material has a service temperature of up to 350 degrees F. Both material types are asbestos free. Extra small and special order sizes are unmarked. All other sizes are printed with a scale in inches, pitch chart, tangent chart and other useful markings. Wrap-A Rounds in 3.88" and 5.00" feature a metric scale and pitch chart.
