3" WIDE COLORED VINYL FLOOR MARKING TAPE - These 6-mil thick adhesive plastic vinyl tapes are available in 14 colors in 36-yard long (108') rolls (on 3-in. cores).  Sold individually or in 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.
