Trinity's radial end door prevents forced entry and reduces openings to a maximum of 3-1/2 inches at the top and 5 inches along the sides. The door can be used on bi- and tri-level cars alike. Light in weight and easy to operate, it requires only periodic lubrication, the company says. Extension kits and upgrade kits for existing equipment are also available.
