ABSTRACT:
A bracket for carrying a plank by means of support legs. The bracket has a cross piece of predetermined length to carry the plank. Open faced channel members are connected at each end of the cross piece. These members extend downwardly and outwardly. The open faces of the channel members open in opposite directions and in the direction of the length of the cross piece. The channel members have internally rounded corners. A bracket sleeve is pivotally connected to each of the channel members for receiving and retaining support legs. The sleeve may be formed with, for example, teeth on one edge to engage the retained leg.
