The fitting comprises at least one strut, a first fastener for releasably securing one end of the strut to the building construction, and a second fastener for releasably securing the opposite end of the strut to the lift mast. The first fastener contains a ball joint to allow restricted pivoting of the strut relative to the building construction in a chosen plane extending through the joint, once the strut has been secured to the building structure. |
