Abstract: A support bracket may include a base portion having an upper surface and a lower surface for resting on a surface, and a mount portion securely mounted on the base portion. The mount portion may include a perimeter wall having a lower end mounted on the base portion such that the mount portion extends away from the upper surface, and an upper end with an upper opening. The bracket may form a socket for receiving a lower end portion of an upright post. The socket may have a cross section size with a width and a depth, and a length substantially equal to the maximum extent to which the lower end portion of the upright post is insertable into the socket. The length of the socket may be greater than approximately two times the width of the socket.
