The 1270, 1280 and 1280R are the Formula 1 Whisper Drive belt drive openers — 1/2 HP units built around the older 12 rib belt. Everything for these openers is on this page: the motor unit, the belts, the safety sensors, the door hardware, the wall control and the remote. Each section has its own diagram, and the reference numbers are specific to the diagram directly above them.
Ordering a belt? The belt is sized to your door height, not your rail. These three openers use the 12 rib 41A3589 belt, stocked in factory and lower cost aftermarket versions. See the belt table below, or use the full LiftMaster belt selector if you are not sure which you need.

These openers take the 12 rib 41A3589 belt. Measure your door opening height, not the rail. We stock the genuine LiftMaster belt and a lower cost aftermarket belt built to the same length, rib pitch and end fittings.

A belt rarely fails on its own. Check the belt pulley bracket, trolley and tensioner while the rail is apart — see all belt drive rail parts.
