We are prepared to furnish any size, bright or black, regular or special. Our specialty is BLOCK CHAIN, such as used on our hoists, and superior quality, CRANE CHAIN. Block Chain is made to a guage block, and is, therefore, the most expensive. We recommend crane chain where block chain is not necessary, as being higher grade, and safer than Common chain. The life of a chain can be greatly increased by frequent annealing and lubricating, and when the wear is not uniform throughout its length it should be cut and pieced where worn. Hoisting and Sling Chains should be annealed once a year, at least, and carefully examined.
