Abstract
An anti-slip grab rail and grab rail assembly, the grab rail providing improved gripping surfaces which, in the preferred embodiments, are formed by a plurality of exposed surfaces of a rigid elongate bar alternating with a plurality of elastomeric members extending longitudinally of the bar. The elastomeric members preferably take the form of inserts secured within cavities that extend longitudinally of the bar at the surface of the bar. The inserts may be secured within the cavities by aligning the inserts adjacent to the cavities and pushing them transversely into the cavities such that the inserts snap into place and are retained by an interference fit with a portion of a structure of the rail. Improved handling, shipping and strength characteristics are attained by manufacturing and shipping the grab rails in comparatively short lengths of four feet or less and by providing key and key-receiving openings in the grab rail and mounting hardware therefor, preferably at both ends of the grab rail, so as to prevent a grab rail from rotating about a longitudinal axis thereof.
