2″ x 50 yards of 3M 983-326 Diamond Grade 6″ white / 6″ read DOT conspicuity tape.
3M® 983 DIAMOND GRADETM CONSPICUITY TAPE: This extremely reflective (TYPE V) adhesive tape is for all kinds of vehicles, trailers, bollards, and barriers.
In daytime the colors are vivid.
The tapes have an acrylic and polycarbonate construction designed to stand up to the rigors of the road and improve the visibility of vehicles and trailers to approaching drivers.
3M® conspicuity markings are six times brighter than conventional markings, reflect at angles approaching 90 degrees, and are highly durable and non-corroding.
(US Federal regulations require semi-trailers exceeding 10,000 lbs. GVWR to have alternating red and white DOT-C2 approved 2-in wide conspicuity tape applied along at least 50% of their lengths and entirely across their back ends.)
This tape is widely used on fire trucks, construction trailers, horse trailers, and RVs.
3M 983 conspicuity tapes are edge-sealed and warranted for 7 years
