Abstract:
An A-frame ladder has a first ladder and a second ladder. The first ladder has two rails interconnected by a plurality of steps and a first set of grooves that receive a gate/barrier device to inhibit a person from using the first ladder's steps. The second ladder also has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the gate/barrier device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps.
