Founded in Cleveland in 1953, fourth-generation family-owned Royal Wire Products manufactures filter bag cages for industrial air-pollution control, custom wire forms and equine wire products. Its patented Twist Lok and Form Lok cage systems reflect a long specialization in industrial filtration, while the Royal Wire Equine division grew from a family saddle-storage invention in 1978. Made in the USA across facilities in Ohio, North Carolina and Nevada, the company serves customers throughout the United States and around the world.
