GENIE 086565.1024.S, CHAIN,RLR,#25 X 64P LOOP
Genie 086565.1024.S is a Genie OEM replacement ansi #25 loop roller chain (ANSI #25 Loop (Endless) Roller Chain, 64 Pitch, 16.0 in). This variant has the following dimensions: Pitch: 0.250 in - Pitch count: 64P - Total loop length: 16.0 in (64 x 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. Construction: Carbon steel, standard finish (unplated). 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.

Frequently Asked Questions
Q: What is the total length of the 086565.1024.S chain and what does 64P mean?
A: This chain has 64 pitches at 0.250 in each, giving a total loop circumference of 16.0 in. It is an endless (loop/riveted) configuration, meaning it has no master link or open ends - the two ends are permanently joined at the factory.
Q: How do I know this is a loop chain and not an open-ended chain?
A: The 1xxx prefix in the SKU suffix (1024) indicates a loop (endless/riveted) chain, as opposed to the 0xxx prefix used for open-ended chains in the 086565 series. A loop chain cannot be lengthened or shortened without breaking and re-riveting the chain.
Q: What are the key ANSI #25 chain specifications for this part?
A: ANSI #25 specifies a 0.250 in pitch, 0.130 in roller diameter, 0.125 in roller width, and 0.091 in pin diameter. The approximate tensile strength is 795 lbf and the chain weighs roughly 0.09 lb per foot. These are considerably smaller dimensions than ANSI #65 chain, which uses a 0.8125 in pitch.
Q: Can I cut this loop chain to a shorter length for my application?
A: No. The 086565.1024.S is an endless loop chain permanently joined at 64 pitches. It cannot be cut to a different length during normal installation. If a different length is required, select the appropriate open-ended variant (0xxx suffix) or a different loop variant such as 086565.1013.S (62P, 15.5 in) or 086565.1033.S (50P, 12.5 in).
Q: Are there any legacy or superseded part numbers that the 086565.1024.S replaces?
A: No legacy or superseded part numbers have been identified for this specific part. Always verify the pitch count and loop configuration against your operator's service manual before ordering to ensure correct fit, as Genie #25 chain variants differ only in pitch count and open-ended versus loop configuration.
