This invention relates to a gravity-feed shelf and to low friction tracks for use in such shelves. The tracks comprise a web panel and an integral flange panel together providing an "L"-shaped structure and are characterized by a frangible zone by which a portion of the web panel can be broken away from an adjacent portion to reduce the width of the web panel, whereby the tracks readily can be adapted for use in conjunction with various sizes of packages and/or single bottles.
