OPERATOR

This is a Whiting door operator (counterbalance) assembly used on roll-up trailer doors. It uses a pair of torsion springs with .187-inch wire diameter and 31-inch coil length on an 87-inch shaft to balance the door's weight, making it easier to open and hold safely. Operators are replaced when the springs weaken, break, or the shaft becomes damaged, restoring smooth door operation and preventing drop hazards.
