Abstract
A barrier assembly includes an upright frame that supports a barrier including a pair of slidably coupled barrier members that are adjustable in length and are supported by a stirrup as well as the frame. The frame attached to the barrier members to support the barrier members is able to attach to a supporting surface. The frame extends upwardly from the supporting surface to support the barrier members at a position spaced from the supporting surface. The frame has a clamp device that engages the members to prevent sliding movement between the barrier members and thereby removably fixes the barrier members at a desired length and fixes the barrier members to the frame.
