The Genie 080839.6051.S is an OEM #65 ANSI roller chain with 605 pitches (approximately 10 ft door height coverage) for Genie commercial door operators using the 6051-series chain specification. This #65 ANSI hardened-steel chain is part of the 6051 series, which covers door heights up to 14 ft (605P for 10 ft, 701P for 12 ft, 797P for 14 ft). It is NOT interchangeable with the 5911-series 10 ft chain (080839.5911.S, 591 pitches), which is designed for a different operator model with a different sprocket center-to-center distance. Always verify your specific Genie operator model before ordering.
A: This chain is #65 ANSI roller chain at 605 pitches (6051 series), designed for Genie commercial operators serving 10 ft doors. The 5911 series uses 591 pitches for the same 10 ft door height - the difference reflects a different operator model or generation with a different sprocket center-to-center distance. The two are NOT interchangeable. Always confirm your operator model before ordering.
A: This chain is rated for Genie 1/2HP commercial door operators that use the 6051 series chain specification. Refer to your operator model number and service manual to confirm the correct series before purchase.
A: The 6051 series covers three door heights: 605 pitches for 10 ft doors (080839.6051.S), 701 pitches for 12 ft doors, and 797 pitches for 14 ft doors. Each pitch count is matched to the specific door height and must not be substituted across heights.
A: #65 ANSI roller chain has a pitch of 0.75 in (3/4 in). It is a heavy-duty chain commonly used in commercial door operator applications and is distinct from lighter-duty #41 chain used in residential or lighter commercial operators. Always verify your operator requires #65 and not #41 before ordering.
A: Genie recommends periodic lubrication of roller chain with a suitable chain lubricant to reduce wear and extend service life. Inspect the chain for stiff links, wear, corrosion, or elongation at each preventive maintenance interval. A stretched or corroded chain should be replaced promptly to prevent operator damage or door failure.
