Many applications require two or more chains, normally with attachments, to run in parallel with “flights” joining the chains together forming a conveyor- or transfer-type system. In these cases, it is critical to have the chains ordered as a set, matched for length, and installed on the machinery with the same relationship to one another as when they were matched.

Diamond Chain Company offers two degrees of precision matching for chains used in parallel operation. Class I matching insures the chains within a given set will not vary in overall length by more than .006″/ft. Class II matching is much more stringent, and assures that the longest and the shortest chain in a given set will not vary in overall length by more than .002″/ft.
