Chain Size and Standard Check
Enter chain dimensions in millimetres or inches (e.g., 1/4, 1 1/2, 3 5/8). For inches, omit the quotation mark (e.g., use 2 1/2 not 2 1/2"). The tool will return the two closest chain standard matches from the database. Distance Score indicates how closely your input matches a standard — the lower the number, the better the match.
