Alpha Cantilever Sliding Gate

The Alpha gate combines optimum quality and security. Strong and clever, this smoothly running gate is available with a variety of infill options, including chain-link and welded wire.

The Alpha Cantilever Sliding Gate

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.
