Page 54 of the Rice Signs 2017 Traffic Safety Catalog covers tall vertical traffic-control devices used to channelize traffic flow in work zones — Channelizer Drums, Grabber Tubes, and Channelizer Tubes. Channelizer Drums (CD series) are 44 inch or 46 inch tall PVC drums with reflective stripes — available with Fluorescent Prismatic (FP) or High-Intensity (HI) reflective sheeting, optionally with a Tire Rubber Base (CD-TRB) for added stability. Grabber Tubes (GT series) are skinny vertical tubes that "grab" attention with 3 or 4 high-intensity reflective stripes, available in 12 inch and 18 inch base diameters. Channelizer Tubes (CT series) are 16 inch diameter, 46 inch tall vertical tubes for permanent or semi-permanent lane separation. Custom imprinting is available on traffic cones and tubes for utility, contractor, and municipal branding.
