Craftsman 54985, 1/2 HP Chain Drive Garage Door Opener
This unit is a little smaller than the others, with a 1/2 HP motor, limiting it for use with single-wide garage doors. It is a simpler unit, but also carries a lower price tag than the others we've looked at. Two wireless controllers come with the unit for use in your cars, as well as a wireless keypad for opening the garage door securely from outside your garage. The rail system is designed to be quick and easy to install, requiring minimal tools. A light beam protects your family and pets from having the garage door close on them. Like the other units, rolling codes are used to prevent others from picking up your code and getting into your home.
