Razor Blade Concertina Coil

A galvanised spring-steel core carrying pressed razor blades, supplied as a concertina coil that expands along the run and clips back on itself.

Three coil diameters: 600 MM for wall tops and short runs, 730 MM as the general-purpose size, and 980 MM where the deterrent has to be visible from a distance. Fitted on top of a chainlink or welded mesh line, or on its own between angle-arm posts.

Specified for substations, warehousing, plantation boundaries and any perimeter where climbing is the actual risk.
