BL646 Leaf Chain | ANSI BL 4X6 Chain 0.75" Pitch - 10ft Box 41B28 Sprockets Dimension (e): 3-3/4"BL646 Leaf Chain is manufactured to ANSI (American) standards and is a heavy duty series of leaf chain. Interestingly enough, BL series leaf chains utilize the same pin diameter as their next chain size up, so BL6 series leaf chains utilize ANSI 80 pins. What this does is greatly increase the working load and tensile of the chain while making it capable of withstanding higher shock loads. The most common applications for leaf chain is forklifts,
