GENIE 080837.0572.S, CHAIN,RLR #41 X 57P
Genie 080837.0572.S is a Genie OEM replacement ansi #41 roller chain - open-ended strand (ANSI #41 Open-Ended Roller Chain Strand - 57 Pitch). This variant has the following dimensions: 57 pitches x 0.500 in pitch = 28.5 in total length; roller dia 0.306 in; roller width 0.306 in; pin dia 0.141 in; plate height 0.475 in. Construction: Carbon steel roller chain; standard finish (non-nickel-plated); steel side plates, rollers, pins, and bushings per ANSI #41 specification. For use with Genie commercial chain-drive door operators and Genie industrial door operators compatible with ANSI #41 chain drive systems. Selecting the correct chain ANSI size, pitch count, and configuration (open-ended vs. loop) is critical for proper installation and operator function.

Frequently Asked Questions
Q: What ANSI chain size is the 080837.0572.S and how does it differ from other sizes?
A: This chain uses ANSI #41 specification, which has a 0.500 in pitch, 0.306 in roller diameter, and 0.306 in roller width. It is a heavier-duty chain than #35 (0.375 in pitch) and lighter than #50 (0.625 in pitch). Always verify your door operator model requires #41 chain before ordering.
Q: What is the total length of the 080837.0572.S chain?
A: The total chain length is 28.5 in, calculated as 57 pitches multiplied by the ANSI #41 pitch length of 0.500 in per pitch. This is an open-ended strand, not a loop or endless configuration.
Q: How do I decode the part number suffix to identify chain size and pitch count?
A: The 080837 series uses a suffix numbering convention where the last digit of the suffix indicates chain size: a suffix ending in 2 denotes ANSI #41, while a suffix ending in 4 denotes ANSI #50. The middle digits of the suffix encode the pitch count (057 = 57 pitches for this part).
Q: Is the 080837.0572.S an open-ended strand or an endless loop?
A: This is an open-ended strand, meaning it is supplied as a straight length of chain without a connecting link pre-installed to form a loop. Installation typically requires a master link or connecting link (sold separately) appropriate for ANSI #41 chain to join the ends if a closed loop is needed.
Q: What is the tensile strength and weight of the 080837.0572.S chain?
A: ANSI #41 roller chain has a rated tensile strength in the range of approximately 2,320 to 2,700 lbf and weighs approximately 0.25 lb/ft. At 28.5 in (2.375 ft) length, the chain weighs approximately 0.59 lb. These values are standard for ANSI #41 single-strand roller chain.
