Genie 086565.0002.S is a Genie OEM replacement ansi #25 open-ended roller chain (Open-Ended ANSI #25 Roller Chain, 54-Pitch, 13.5 in). This variant has the following dimensions: Pitch: 0.250 in | Roller dia: 0.130 in | Roller width: 0.125 in | Pin dia: 0.091 in | Overall width: 0.306 in | Plate height: 0.228 in | Pitch count: 54P | Total length: 54 x 0.250 in = 13.5 in. Construction: Standard carbon steel roller chain; no plating. For use with Genie chain-drive residential door operators and Genie chain-drive commercial door operators. Selecting the correct chain ANSI size, pitch count, and configuration (open-ended vs. loop) is critical for proper installation and operator function.

A: This part is an open-ended (non-looped) length of ANSI #25 roller chain cut to 54 pitches, giving a total length of 13.5 in. It is not a loop or endless chain. Open-ended chains are installed by threading them into the drivetrain and connecting the ends with a master link or other fastener during assembly.
A: The total chain length is calculated as pitch count multiplied by pitch length: 54 x 0.250 in = 13.5 in. This is the center-to-center span of the chain when laid flat end to end.
A: No. Part number 086565.0002.S is a standard carbon steel chain with no plating. Nickel-plated variants in the 086565 series carry a different suffix. If corrosion resistance is required, verify whether a nickel-plated or stainless alternative is offered for your specific operator model.
A: Other open-ended variants in the 086565 series include 086565.0026.S (#25 x 22P, 5.5 in) and 086565.0004.S (#25 x 44P, 11 in). Loop variants include 086565.1033.S (#25 x 50P loop), 086565.1013.S (#25 x 62P loop), and 086565.1024.S (#25 x 64P loop). Select the part number that matches the pitch count required by your specific operator model.
A: ANSI #25 roller chain has a nominal tensile strength of approximately 795 lbf. This rating applies to the chain itself under static test conditions. Always follow Genie operator installation guidelines for actual load and duty-cycle limits applicable to your specific door operator model.
