A shelf bracket composed of a generally L-shaped bracket member and a strut member connected to distal ends of the bracket member. The bracket member comprises a perimeter flange extending angularly from substantially the entire perimeter of the bracket member and extending as an unbroken continuous structural element at the distal ends of the bracket member. The strut member comprises a projection at one end that engages a socket formed in one of the distal ends of the bracket member. The strut member comprises another end frictionally engaging an inside surface portion of the perimeter flange at the other distal end of the bracket. A fastener increases the strength of the connection of the strut and bracket member and is located at the distal end of the bracket member that frictionally engages the strut member. The bracket member further includes a projection spaced from the socket for releasably engaging the strut member for inhibiting withdrawal of the strut member from the socket.
