Sauber turret trailers are equipped with one or more rotating turrets. The turret frames are galvanized and can be removed, allowing the trailer to be used for other applications. These individual frames can also be used on other transportation equipment to string wire. The turrets are free turning and can be locked on six degree intervals by the stainless steel locking handle. Always stop the reel rotation before locking it into place. Large forces from heavy, turning reels can damage the locking mechanism if an attempt is made to lock the reel while rotating.
