Product Overview
The LiftMaster 041A5807 is a 7-foot chain and cable replacement kit for select chain drive garage door openers. The chain and cable assembly connects the opener sprocket system to the trolley so the opener can move the door along the rail. When this assembly is stretched, kinked, rusted, broken, or installed on the wrong rail length, the opener may be noisy, slip, fail to travel fully, or come out of adjustment.
This part is door-height and rail-system specific. It is intended for compatible chain drive openers on 7-foot garage doors, not for 8-foot or 10-foot door extensions. The exact model list is broad, especially across Chamberlain and LiftMaster branded chain drive units, but the safest match is still the opener model and rail parts diagram.

Technician Note
Chain and cable kits must match the rail and door height. Installing a 7-foot chain on an 8-foot or 10-foot rail setup will create travel and tension problems.
Before Ordering
- Confirm the opener is a compatible chain drive model
- Confirm the garage door is 7 feet high and does not use an extension rail
- Inspect the sprocket, trolley, rail, and tensioner before replacing the chain
- Compare the original chain/cable path and adjustment method before installation
Important Ordering Warnings
- Do not use this kit on belt drive or screw drive openers
- Do not use the 7-foot kit on 8-foot or 10-foot doors
- Do not overtighten the chain after installation
- If the door is heavy or the rail is damaged, correct those issues before replacing the chain and cable
Professional Advisory
Chain and cable replacement requires proper rail tension and travel setup. If the chain repeatedly loosens, jumps, or binds, the opener rail, sprocket, trolley, or door balance should be inspected by a technician.
