A durable cast iron frame is standard for both floor and riser mount conditions, with integral arm rests and space for row identification plates. Double-walled, blow-molded plastic seat and back are contoured for comfort. Ultraviolet inhibitors prevent cracking and high quality pigment resists color fade. Self-rise hinge design is open, allowing water and other liquids to pass through, thereby preventing rust and corrosion of metal parts. Seats rise to 3/4 fold position to allow maximum row clearance for easy access and egress, as well as hands-free sitting. Multi-step paint and finish processes ensure longevity of exposed cast iron components. A wide array of sizes and accessories are available, including custom molded colors, graphics and standard options and ADA accessible ends.
