The LiftMaster 19-5114 #41 Chain for 14' Door is a replacement drive chain engineered for LiftMaster chain-drive trolley operators configured for taller sectional overhead doors. As part of the opener’s rail assembly, this ANSI #41 roller chain links the trolley to the drive sprocket to move the door smoothly through its open and close cycles. It’s intended for maintenance or repair where the original chain has stretched, worn, or been damaged, restoring dependable travel and consistent performance on 14-foot door applications.
This OEM-designated component is compatible with LiftMaster chain-drive trolley systems that specifically call for #41 chain and a 14' door rail setup; it is not for belt-drive units or operators that require other chain types. Installation follows standard service procedures: route the chain on the rail, connect it with the appropriate master/connecting link specified by the opener, set proper chain tension, and recheck travel limits and safety reversal per the operator’s manual. Always disconnect power before servicing and verify compatibility by referencing your LiftMaster parts diagram or model documentation using part number 19-5114.
