Our barricades are manufactured in house and are NCHRP 350 approved. The Cantel E-Z Up barricade is on the ODOT Qualified Products List. Materials used are: Sturdy MDO plywood panels, 12 gage galvanized legs on type I & II and 1/8 inch white enamel steel legs and stands on type III with plated hardware and lock nuts on all. The reflective sheeting is available in either approved engineer or high intensity. These are the same barricades we use in our rental stock, they hold up very well to abuse and are repairable. All three configurations are available (type I-II-III).  All are available with lights.
