Genie 086565.0026.S is a Genie OEM replacement ansi #25 roller chain - open-ended (Standard Open-Ended ANSI #25 Roller Chain, 22 Pitches, 5.5 in). This variant has the following dimensions: Pitch: 0.250 in - Pitch count: 22P - Total length: 5.5 in (22 x 0.250 in) - Roller diameter: 0.130 in - Roller width: 0.125 in - Pin diameter: 0.091 in - Overall width: 0.306 in - Plate height: 0.228 in. Construction: Carbon steel - standard finish (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.

| Item Type | ANSI #25 Roller Chain - Open-Ended |
| Materials | Carbon steel - standard finish (no plating) |
| Dimensions | Pitch: 0.250 in - Pitch count: 22P - Total length: 5.5 in (22 x 0.250 in) - Roller diameter: 0.130 in - Roller width: 0.125 in - Pin diameter: 0.091 in - Overall width: 0.306 in - Plate height: 0.228 in |
| Mounting | Internal drivetrain installation - open ends allow direct connection to operator drive sprockets using appropriate master link or connecting link for ANSI #25 chain |
A: This chain uses the ANSI #25 standard, which has a 0.250 in pitch - significantly smaller than the #65 chain (0.8125 in pitch) used in Genie's 080839 and 109269 series. Always verify the chain size marking on your operator before ordering.
A: The 086565.0026.S is an open-ended chain, meaning it has two free ends and is not formed into a closed loop. This distinguishes it from loop (endless/riveted) variants in the 086565 series such as 086565.1033.S or 086565.1013.S.
A: The total length is 5.5 in, calculated as 22 pitches x 0.250 in per pitch. This is the shortest open-ended variant in the 086565 series, making it suitable for shorter internal drivetrain runs inside the operator head.
A: The approximate tensile strength of ANSI #25 roller chain is 795 lbf. This is inherently lower than #65 chain (~13,200 lbf) due to the much smaller pitch and component dimensions, so it is intended only for light-duty internal drive applications as designed by Genie.
A: The 086565 series uses standard carbon steel construction with no special plating. If a corrosion-resistant finish is required, consult Genie for alternative options, as a nickel-plated #25 equivalent is not listed in the current research data.
