The Impact Recovery Systems (IRS) Yellow Long Squeeze Top Flexible Delineator is a TUFF Post®. They are designed to meet the harsh demands of high speed and high traffic areas. The posts have been tested to sustain 50 impacts at 80 km/h with little damage to the unit and to the impacting vehicle, while remaining upright with no vertical listing. These posts are ideal for exit lane delineation, head-to-head traffic separation, urban turn restrictions, edge line delineation, or anywhere that durable, flexible, high performance channelization is required.

IRS Posts work in conjunction with IRS Bases and Lag Bolts.
