We installed this 6' tall chain link with barbed wire system recently for a water works facility. Features an exit loop (coiled wires installed in the driveway which activates the gate when a vehicle passes over the loop), keypad, and remotes, plus all safety equipment. Gerald, Abram and Manny kept the project running smoothly. All automated sliding gates must conform to strict safety standards. There are safety sensors and both opening and closing edges of the gate, and a photo eye across the driveway to ensure that nothing/nobody gets trapped. The operator also has inherent reversing sensors for additional safety.
