Cable clips FLOP type of PE reinforced with hardened nail fastening apply to a single round cables. The hardened nail is pressed into clip body, which allows the use of clip on different surfaces (wood, brick, concrete, aerated concrete, etc.) with a hammer. Reinforced PE has increased resistance to mechanical damage and hardened nails allows attaching a cable to the hard surfaces (concrete). Cable clips can be attached a wide range of cables or wires, which do not require a strong, rigid attachment to the substrate.
