3" WIDE COLORED VINYL FLOOR MARKING TAPE - These 6-mil thick adhesive plastic vinyl tapes are available in 15 colors in 36-yard long (108') rolls (on 3-in. cores).  Sold individually or in 16-roll cartons, these floor tapes are used for designating OSHA safety, caution, and hazard areas on plant and warehouse floors.  In areas of heavy use, an overlay of clear 4-inch vinyl tape (seen below) improves floor marking tape's durability and lifespan.  These tapes are very adhesive and resistant to water, oil, fungus and chemicals, have a semi-gloss finish, and can be written on with permanent markers.  A lower cost alternative to 3M #471.  ("X" in photo = discontinued color).
