3M ENGINEER GRADE REFLECTIVE STRIPING TAPE - 3M Scotchlite 5100 Series (see Sell Sheet) reflective tapes are pliable and conformable and can be applied to many different surfaces. Reflective striping makes hydrants more visible at night where they might not be seen. Striping of fire hydrants is done to indicate flow rate (see rate table to right). A hydrant may have a bonnet edge thickness or width of up to 2-1/2" and a circumference of up to 40 inches. 3M Engineer Grade conforms over its center bead. In the case of placement on the hydrant barrel, a typical circumference is around 28 inches. Note that the gap between the bottom of a bonnet and the nozzles may be as little as 1-1/2". Identi-Tape offers 1" and 2" widths in the four NFPA flow-rate colors. This tape is also great for marking fire tools so they can be found in darkness because it lights up before flashlights. Black reflective tape is popular on motorcyles and with the military.
3M 5100 series Scotchlite Engineer Grade reflective tapes are TYPE I and conform to the requirements of ASTM D4956 for reflectivity, longevity, and resistance to weathering. They are 7-mils in thickness and have a peel-off backing, having an adhesive that allows the tape to be repositionable and removable (see 3M's product bulletin). They should be applied within the temperature range of 55ºF to 100ºF, but are service rated from -30ºF to 200ºF. Multiples of short lengths of the same color will be sent as a continuous roll unless specified otherwise in the "comment box" when checking out.
