The Impact Recovery Systems (IRS) White Sta-Rite Flexible Delineator Post is constructed of white powder coated aluminum to prevent warping and remain straight. The outer yellow bollard is a durable plastic which simulates a formidable concrete barrier for added conspicuity and prevents bumper damage to metal post. Every unit has a reactive spring assembly that allows the signpost to be bumped by vehicles, rebound, and return upright.

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