A bracket for adjustably mounting a timber member on a rack is disclosed which has a U-shaped band with two vertical arms joined by a horizontal base, with each arm having a fastener hole to permit rigid fastening of a timber member within the arms of the band. An L-shaped hook extends outwardly from one arm and is in substantially the same plane as the arm. The hook is adapted to engage within a slot in a vertically mounted rack. An end plate is preferably attached to the band perpendicular to the band so as to resist movement of the timber member within the band parallel to the arms and in the direction of the hooks. The hook preferably has a portion adapted to engage in the slot in the rack which is tapered so as to permit a wedging of the hook into the slot. A kit for the assembly of timber members into a structural frame of this invention comprises a rack with a plurality of vertically spaced slots with fastener openings to permit mounting the racks to the face of a timber beam and a hook bracket. Frame structures may be assembled from the kit by mounting hook brackets with leftwardly and rightwardly extending hooks on opposite ends of a horizontal timber member and engaging the hooks within slots of racks mounted to vertical timber members. Common structural frames such as shelves and workbenches may be constructed from the hardware of this invention.
