Reflective clearance markers Davidson Traffic Control Products introduced its Clearance Marker, a permanent flexible marker designed for visibility and low maintenance. The Clearance Marker is a 12-inch-long reflective marker that tells switching crews how far they can shove a car without fouling the adjacent track. Clearance Markers are constructed of highly-durable thermoplastic polyurethane that provides flexibility and durability. Clearance Markers are said to remain extremely flexible, even at extreme temperatures and rebound to an upright position after being bent over. The large cube-corner prismatic reflective element makes the markers highly visible at night. Phone: 253-284-8000.
