Tuff Curb® XLP is a longitudinal channelizing curb system produced by Impact Recovery Systems, Inc. Tuff Curb® XLP consists of two pieces. One is a single piece curb section measuring 40 inches long x 8 inches wide x 2 inches high made of High Density Polyethylene and weighing approximately seven pounds. It is attached to the roadway by way of lag bolts through two or three anchor holes within the curb or with highway grade adhesives.
