US TYPE HOLDERS NEW TECHNOLOGY OF WIRE FASTENING Self-fastening holders US1, US2 and US3 are a novelty in the area of wire fastening. They are designed to fasten electric wires on and under the plaster, teletechnical wires, cable and satellite TV wires and floor heating system wires. The US holder fastens wires of 14 mm maximum external diameter or flat wires of 15mm width without the need to use pegs and screws. The holders are fastened by pushing into a drilled hole Ø 9 or Ø 10, depending on the base. If the Ø value of the external diameters of wires to be fastened is lower than 6, three holding notches should be cut off on one side, leaving another three on the other side of the holder. Then drill a hole of Ø 7 and fasten the holder in it. The use of the US holder allows to reduce the time and cost of the installation and makes the fittings more aesthetical. HOW TO FASTEN We introduce the US holder with a wire placed in it (see picture) into a drilled hole of Ø 9 or Ø 10, 40mm length. It is recommended to keep a 250mm distance between the holders.
