The gatebar prevents access to the steps when the brake is not applied. It is welded to the handlock and is a bar that protrudes between the 3rd and 4th steps. When the brake is off, the bar falls back out of the way, behind the treads. The gatebar is a safety feature fitted to the handlock. When the steps are mobile a bar protrudes between the 3rd and 4th treads to prevent access. When the steps are stationery the bar falls back out of the way, behind the treads.
