Highlighted rows are sizes we carry; the certification column shows whether we supply them with Lloyd’s Register (LR) or American Bureau of Shipping (ABS) certificates. A dash means the size is available to order. Dimensions are approximate and vary slightly between forgings; a blank means we do not hold an A/B/C figure for that size on file. Chain is sized on nominal diameter with a manufacturing tolerance of ±2.5%, so a nominal 26 mm bar measures between 25.35 and 26.65 mm.
