A wall or ceiling mountable bracket, used in pairs, for storing and displaying board-based recreational equipment includes a generally U-shaped body having structurally-reinforced elongated front and rear portions and a spacer portion extending between and rigidly interconnecting them so as to hold
A wall or ceiling mountable bracket, used in pairs, for storing and displaying board-based recreational equipment includes a generally U-shaped body having structurally-reinforced elongated front and rear portions and a spacer portion extending between and rigidly interconnecting them so as to hold them in a spaced apart relationship which forms an elongated channel between them being open at one end and along opposite sides and closed at an opposite end for receiving board-based recreational equipment in the channel. The bracket also includes structures providing access through the body to facilitate fastening the body with its rear portion located against a support structure. The access providing structures define at least two bores, one through the rear portion and the other through the spacer portion and through segments of the front and rear portions aligned with and connected to the spacer portion.
