The Acme CS1 3.5mm meets the specifications of ISO 17712:2013
 
The lock body is manufactured from die-cast aluminum and the cable from non-preformed galvanized steel.
The cable has a welded tip for ease of locking and should the cable be cut it unravels making it impossible to re-lock the seal again without showing obvious signs of tampering.
This cable seal requires cutters for removal.
 
Diameter of cable: 3.5mm
Length of cable: 300mm
