This document is a Salient Characteristic specification for a C2162H Fish Screen Roller Chain. The chain features a 4-inch pitch, 2.25-inch roller diameter, and 1.25-inch width between roller link plates, with an average tensile strength of 58,000 lb. Key technical specifications include 30 links per 10 feet, a heavy sidebar type, and epoxy-coated links in low gloss black applied electrostatically before assembly.

Material and construction details highlight precision engineering: hinge pins are Nitronic 60 stainless steel, bushings are 17-4 PH, rolls are carbon steel-case hardened, and cotter pins are Type 302 stainless steel. The chains are prestressed and matched in pairs with a maximum variation of 0.030 inches, and are designed with no lubrication requirements. The specification adheres to ANSI B29.4 requirements and includes a reference to an attached drawing for link plate details.
