ixty-five percent of the openers sold today are chain driven. Here's why: durability, reliability and lasting performance. LiftMaster offers the widest variety of chain drive garage door openers.

For greater security, our chain drive openers include Security+® rolling code technology. Each time the remote is activated, Security+ automatically rolls the code over to any one of 100-billion new codes, never to be repeated. We also include PosiLockTM, a patented LiftMaster feature. With PosiLock, once your garage door goes down, it is securely locked and an intruder cannot gain entry by forcing your garage door open.

For safe operation, every model is equipped with the Protector System®, which projects an invisible light beam across the inside of the garage door opening. If anything interrupts the beam while the door is going down, the door automatically reverses before making contact.

Please note: all chain drive models are available in 7', 8' and 10' models.
