1/2 hp Sears garage door opener, complete with bar and chain and brackets. Motor works good but nylon gear has worn out. Bought and installed a new opener complete before finding out that a kit is available for this one for $42.00 which includes new gears. With the kit, and low price of this unit, you can have a door opener for hundreds of dollars less than a new one. This one lasted about 30 years before the gear wore out...new gears with kit should do the same.
