Abstract
An adjustable load-bearing apparatus capable of being operatively disposed on the end of an elongate structural member having a substantially fixed length so as to produce a structural member having an adjustable length. The apparatus includes a saddle for receiving a load-carrying beam, at least two adjustment screw members fixedly attached to the saddle, and respective nuts which bear on a bearing surface of a cross-bar disposed on a bearing plate. A guide sleeve depending from the saddle and slidable longitudinally along a portion of the elonate structural member provides moment coupling between the saddle and the elongate structural member, without subjecting the adjusting screws or nuts to bending moments.
