The U-clamp  is a time-saving and cost-saving pipe clamp and cable clip for directly fixing conduits to fischer mounting rails FUS in buildings. The FUBD without a sound insulation insert is ideal for fixing conduits made of metal or plastic, or cables, with an outer diameter of 35 to 100 mm. In the pre-mounted U-clamp, a pressure cup is supported by a screw plug that ensures optimum adjustment in line with the outer diameter of the conduit and also acts as a fixing aid. This means that additional accessories such as threaded rods and channel nuts are not necessary. This saves time and money.
