Abstract
A combination tool for installing and crimping a cleat for fastening sections of ductwork, and for adjusting the threaded on support rods of strut channel for leveling the ductwork. The tool has an installing plate for holding a cleat and a removable handle that threads to the back of the installing plate. The handle has a hollow tubular body with a nut driver formed in the other end, for engaging and driving a threaded nut. The nut driver end is made by milling a rectangular slot transverse the axis of the hollow tubular body to form a pair of nut-engaging. A shank can be provided for attachment to the chuck of a power drill for rapid driving of the nuts. The tool also has a hinged crimping plate with threaded set screws for crimping the cleat securely to the flanges of the ductwork.
