A kit is provided for assembling a modular bracket (1) used, in particular for placing gripping and clamping devices or clamping components, in particular metal sheets on an assembly line. The kit has a base part (3) fixable on a solid support or a carrier, a tube (4) fixable to the base part (3) and a head part (5) which is fixable to the tube (4). The head part includes connecting surfaces for fixing the gripper on the clamping device. According to the invention, the head part (5) is continuously height-adjustable with respect to the tube (4), is pivotable about the central longitudinal axis thereof and, afterwards, frictionally and form-fittingly connectable to the tube (4).
