Abstract
A barrier system includes a handrail, and a connector to couple the handrail to a post extension that extends upward from a floor. The handrail has and end with a width measured in a direction transverse to an elongate length of the handrail. The connector includes a socket to hold the end of the handrail. The socket is defined by an elongate channel that extends in a direction substantially parallel to the post extension when the connector is attached to the post extension. The channel has a length that is greater than the width of the end of the handrail.
