Chain from Nigel Rose Marketing Services Limited – as you would expect from a physical security wholesaler, our range of chain is very extensive. We have mild steel, steel, Hardened Steel and specialist alloys like Molybdenum. So it is possible to choose the right type and size to suite the security requirement. Some have integral padlocks or locking mechanisms which can be key or combination operated, while others require the addition of a padlock of a similar security level. The offering includes Molybdenum and steel from IFAM of Spain, Hardened Steel from Master Lock of America and Hardened Steel from Oxford Products of England. Some of the Oxford Product offering have also been tested and passed several categories MotorCycle Gold standard from Sold Secure the independent testing house wholly owned by the Master Locksmiths Association of Great Britain. Different ranges have different coverings – some have a hard wearing fabric covering whilst others are plastic coated.
