JBC's retractable cone bars are designed to work with traffic cones or N-Top delineators. This cone bar adjusts and retracts from 3' to 6' feet in length and comes complete with reflective yellow / black sheeting for maximum visibility day or night. Extremely portable and easy to install. Just drop the Cone-Bar ring onto the top of the cones or delineators to create an instant traffic barricade for hazardous locations such as manholes, or other controlled access areas. Save time and money! Using four JBC Traffic Cones or delineators (sold seperately) and four Cone-Bars, a worker can set up a 10' by 10' barrier in less than one minute. The Cone-Bar system is the most efficient cost effective warning barrier available. 20 Retractable cone bars per case, Sold individually.
