Abstract: A gate arm for a swing gate incorporates a release mechanism that releases the gate arm and therefore allows the gate to swing freely about its hinges when inwardly-directed pressure applied to the gate exceeds a threshold level. The gate arm also includes a spring-loaded pivot joint that applies pressure to the gate when the gate is operating normally and is in the closed position, and further works cooperatively with the release mechanism to prevent damage to the operator and gate arm when the gate is forced open.
