John King’s unique relieved plate allows for maximum integrity flush weld with minimum weld projection beyond the angle. This ensures flatness and ensures the weld is not exposed to wear and premature failure.

This format is a popular choice in milling applications. Chains conform to British standard BS 4116 and operating in twin strand format with strands made common with a flight bar bolted to a welded angle iron L style attachment. Often described as shrouded chain it is encapsulated within a channel form as part of the conveyor panel profile and as such is separated from the material. Clearly the UTS is double that of single strand. The real advantage is an open discharge area which is beneficial for sticky materials and reduction in carry over.
