Control System Hardware

Sullivan control system hardware is engineered to be the best you can buy. Every component is designed to be simple to install and unbreakable under normal conditions. Our Gold-N-Clevises are widely recognized as the very best made, our steel control horns are strong, stiff and light, and our ball joints are the only links that have a locking sleeve. Only the very best materials are used: hardened, tempered steel, Valox®, glass reinforced nylon and nickel are among the specifications. We make nearly every component needed to transmit motion from a servo to a control surface. If you have specific application questions, our product engineers at tech@sullivanproducts.com or at 410-732-3500 will be happy to assist.
