Non-standard Series Chain

Non-standard chains were introduced prior to the adoption of the ASME / ANSI standards. After industry's adoption of ANSI standards many of these chains became the current Standard or Heavy Series chains, but some did not. Diamond recognises that a considerable amount of industrial equipment still utilises these unique chains and so whenever possible we continue to produce them. The information below may be useful in identifying your "non-standard, but still very important" model.
