Abstract
A versatile framing system incorporates open channel members and closed tubular members. The closed tubular members provide strength, while the open channel member allows various members to be attached at an infinite number of positions along its length. The inventive system thus successfully incorporates the advantages of both open channel members and closed tubular members.
