摘要

The threaded bush for aluminum profiled rails is in the form of a metal elongated cylinder of quadratic or preferably round cross-section which in its longitudinal axis a concentric threaded hole and beneath this a second threaded hole at right angles to it and reaching through the center axis of the cylinder and with a length which corresponds accurately to the diameter of the cylinder. The threaded bush in the form of a cylinder is installed in general in the assembly channel of extruded housing profile and is locked by a screw fitting in the transverse hole.
