The Alpha Gate, manufactured with an internal tensioned aluminum beam, is known for its engineered strength and durability. Wallace Perimeter Security has designed the chain-linked Alpha Gate to provide strength, security and protection in high traffic commercial applications. The modular aluminum gate is powered by our innovative Kinetic motor. This motor is a key component, with its rack and pinion drive, providing a smooth and quiet operation. The variable-speed drive maximizes the gate hardware life, eliminating the instant start-and-stop motions of traditional, constant-speed motors.
