BARRIER HEIGHT EXTENDER

Devices for extending the height of a barrier are provided. The devices comprise an elongate member having a downward-facing rail channel comprising a plurality of opposed longitudinal projections extending inwardly into the rail channel, a decorative accent feature mounted on the top surface of the elongate member and extending upwardly therefrom, and a top rail mounted onto a top surface of the decorative accent feature. The devices are configured for downward installation onto the top rail of a barrier panel, whereby a first pair of the opposed longitudinal projections rest on any upwardly facing surface of the top rail, while at least one further pair of the opposed longitudinal projections contacts the opposing side-facing surfaces of the top rail. Also provided are systems comprising these devices, as well as methods for installing these systems onto the top rail of a barrier panel.
