ANSI AL Series & BL Series Leaf Chains

BL5 series leaf chains carry a ⅝-inch pitch, the step between the BL4 and BL6 series, with tensile strength from 3,600 lbs on the BL522 up to 38,100 lbs on the BL588. Lacing options run from 2x2 through 8x8, so the same pitch covers both light-duty pulleys and heavier lifting setups. Full specs for BL522 through BL588 are below.

BL6 series leaf chains use a ¾-inch pitch and span from 14,100 lbs of tensile strength on the BL622 up to 53,682 lbs on the eight-strand BL688. It's a common size for forklift mast chains and general power transmission work where a ¾-inch pitch fits the sheave. See the BL622 through BL688 specs below, including pin diameter, plate height, and weight per foot.

BL8 series leaf chains run on a 1-inch pitch and cover the widest strength range in this pitch class, from 24,300 lbs on the two-strand BL822 up to 92,000 lbs on the eight-strand BL888. Models like BL834, BL844, BL846, and BL866 are common choices for heavy-duty lifting and mast assemblies. Full lacing, pin, and plate specs for each BL8 model are listed below.

BL10 series leaf chains move up to a 1¼-inch pitch, with tensile strength from 33,000 lbs on the BL1022 up to 124,700 lbs on the BL1088. This pitch size shows up often in larger forklift masts and heavier material handling equipment, where the added pitch length carries more load per link. Specs for all seven BL10 lacing options are listed below.

BL20 series leaf chains are the largest pitch Dixie stocks, at 2½ inches, with tensile strength ranging from 102,000 lbs on the BL2022 up to 409,000 lbs on the eight-strand BL2088. These chains are built for the heaviest lifting and hoisting equipment, where load capacity matters more than compact size. Full specs for BL2022 through BL2088 are below.
