Our Grabber 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 firmly in place. *Rubber base is made from 100% recycled rubber. *NCHRP 350 Tested Crashworthy, Certified by FHWA Acceptance Letter WZ-24. *With the convenient Grabber Tube handle, you can easily and quickly tie or wrap caution tape from one tube to the next. The innovative handle design enables you to easily move, set, drag, or lift the Grabber Tube.
