Cable holders with a hardened nail of the "FLOP" type for round and flat cables enable simple and quick installation of cables to the walls of buildings. Cable clips with a FLOP nail are designed for fixing wires or individual cable strands to the base with a nail. Fastening is done by driving a hardened nail into the ground. Holders of this type are used when it is necessary to obtain quick and reliable fastening, especially in wooden or aerated concrete substrates. If it is necessary to attach the cable to a surface with a high degree of hardness (e.g. concrete), it is recommended to use wall plugs or other types of holders.
