Sealed ball bearings, fully enclosed roller chain and drive system, along with permanently lubricated pulleys alleviate the need for routine maintenance. There are other features as well: Cable wound on large grooved winders dramatically increase cable life. Aluminum construction resists corrosion. Less costly installation with fewer pilings required and lower power requirements. Options: Remote Control Stop attachment to program pre-determined up-and-down positions Solar power
