Nail disc NSB

The secure cable fixing in wall slots

The fischer nail disc NSB is a cost-effective solution for the flush-mounted fixing of cables in wall slots and to wood constructions. The nail disc, consisting of high-quality polypropylene and a hardened, zinc-plated steel nail, is already pre-mounted. The nail disc is positioned and the nail is hammered in. The vaulted structure of the nail disc ensures an optimal cable contact pressure and therefore a secure hold. The flat nail disc protrudes only slightly, and can therefore be easily plastered over.
