The stem of the Looper-Tubes are made of flexible yet durable fluorescent low density polyethylene material, with UV inhibitors to minimize fading. The recessed areas on the stem protect the reflective bands, minimizing rips and scratches. The extra large flange at the bottom of the stem allows the rubber base to hold it firmly in place. The unique “loop” style handle makes grabbing and moving the Looper-Tube a breeze! Even on and off the bed of a work truck! Closing off an area of the job site is quick and easy when utilizing the “loop” style handle with two (2) or more Looper-Tubes tied together with caution tape, flag line, or rope.
