Finish Line tape material

[FRC340]

From Section: 6.2.1: Boundaries and Markings

A red or blue “FINISH LINE” is marked on each side on the carpet under the OVERPASS. The FINISH LINE is indicated by a six-inch wide tripe of black-and-white checkered tape, followed by a two-inch wide stripe of colored gaffers tape. The pipes of the OVERPASS structure coplanar with the vertical projection of the gaffers tape are colored to provide further indication of the plane of the FINISH LINE. For the red FINISH LINE, the gaffers tape and pipes are red, and for the blue FINISH LINE the gaffers tape and pipes are blue.
Arena Layout and Markings Has this text for the lines as 3" TAPE BLK/WHT W/3" STRIPE EVERY 3", TWO STRIPS

Is there a source for this finish line tape? All that I can find is a 2 inch tape, or a 3 inch tape, with 3 rows.

The checkered tape was custom printed and is not available by roll, or even by case. For large volume orders (80 rolls minimum), you can contact the original vendor, Wholesale Tape, at 1-800-642-8273. The tape is white 3-inch gaffers tape, printed with a 3-inch square black checkerboard pattern.

If "close enough" is "good enough" for your purposes, 1" vinyl checkered tape is readily available from such sites as http://www.findtape.com (click on "Racer's Tape").
