Frequently Asked Questions
Q: Which Genie operators is the 080839.6871.S chain designed for?
A: This chain is engineered for Genie 5911-series commercial operators sized for 12 ft door applications. It has 687 pitches at a 0.75 in pitch. Do not substitute the 6051-series 701-pitch chain (part 080839.7011.S), which is also rated for 12 ft doors but is designed for a different operator generation with a different sprocket center-to-center distance - the two are NOT interchangeable.
Q: Can I use this 687-pitch chain in place of the 701-pitch chain for a 12 ft door?
A: No. Although both the 5911-series 687-pitch chain (080839.6871.S) and the 6051-series 701-pitch chain (080839.7011.S) are used with 12 ft doors, they suit different operator models with different sprocket-to-sprocket distances. Installing the wrong pitch count will result in improper tension, accelerated wear, and potential operator damage. Always verify your operator series before ordering.
Q: What does the '687P' designation mean and what other pitch counts are in the 5911 series?
A: The chain is #65 ANSI standard with a pitch of 0.75 in and a total of 687 pitches, yielding an overall chain length sized for 12 ft door travel in compatible 5911-series Genie commercial operators. The 5911 series also includes 591P (10 ft), 783P (14 ft), 879P (16 ft), 975P (18 ft), and 1071P (20 ft) variants for other door heights.
Q: What material is the 080839.6871.S chain made from?
A: The chain is constructed from hardened steel throughout, consistent with the Genie 080839 heavy-duty commercial chain specification. This provides the strength and wear resistance required for high-cycle commercial garage door operation with 1/2HP operators.
Q: How do I verify this is the correct chain for my Genie operator before purchasing?
A: To confirm compatibility, identify your Genie operator model number from the label on the operator head. Cross-reference that model to the 5911 series. If your operator uses a different sprocket center-to-center distance corresponding to the 6051 series, you will need the 701-pitch chain instead. When in doubt, contact Genie commercial parts support with your full operator model number before purchasing.
