Wayside Exhibit Low-Profile Bases

Wayside exhibit bases are designed to accommodate a variety of flat panels. A standard base consists of a frame, which holds the exhibit panel, and legs, which hold the frame and panel at the preferred viewing . Most exhibit bases are installed by directly burring their legs into tamped dirt, but—as illustrated in the Custom Bases section below—can be adapted to a variety of site conditions.

Exhibit panels can be easily replaced by unscrewing the tamper proof screws (special bit required) in the back of the top capture rail.

This model should only be used for consistency concerns if replacing a single or small number of bases near or next to existing T-style bases.
