Cable clips with a hardened "FLOP" nail for round and flat cables enable quick and easy cable installation on building walls. Cable clips with a FLOP nail are designed to secure cables or individual cable cores to the substrate using a nail. Fastening is achieved by driving a hardened nail into the substrate. These clips are used when quick and secure fastening is required, particularly in wooden or aerated concrete substrates. If a cable needs to be secured to a hard substrate (e.g., concrete), it is recommended to use expansion bolts or other types of clips. Halogen-free.
