A glide ( 20 ) includes a base ( 22 ), a front member, and a number of walls ( 26 ) extending front-to-back. Both the base and the front member are advantageously formed as a number of pieces secured side-by-side to provide expandability. The front member may be secured to the walls via dovetail interaction and different front members may be provided for different wall spacings.
