BL / LH Series ( Leaf Heavy) leaf chains consist of link plates which are thicker and larger in contour than the AL Series link plates of the same pitch. The link plates have the same thickness as the link plates of the next larger pitch size in ANSI roller chains. The pins have the same diameter as those of ANSI roller chains of the next larger pitch.
