The primary part of the rack is a beam having an essentially H shaped cross section having two sides and a web interconnecting them. A length of bungee cord is threaded through a series of holes in the web to provide a series of exposed, end to end lengths of the cord, each length being usable to retain a stored object against the edges of the sides of the beam. In one embodiment of the invention pins may be inserted in holes across the beam to provide spans of cord shorter than the distance between holes. In an alternate embodiment clips engage the cord and are attachable to the web at any of a plurality of openings. The pattern of the installation of the cord is such that the length of cord serving each exposed length is approximately 3 times the exposed length.
