Chain Drive Openers
Chain drive openers are basic traditional garage door openers. A chain, similar to a bicycle chain, is used to guide a trolley. This trolley connects the door to the opener in order to operate the door. They are priced affordably, are fairly reliable and only occasionally need to be maintained or repaired. However, chain drive openers tend to be louder than a belt or screw drive opener. The operating noise level is something to consider.
Belt Drive Openers
Belt drive garage door openers are known for being quiet. They use an automotive style belt rather than a chain as well as a trolley, just like the chain operators. The belts made of neoprene, reinforced rubber or fabric covered, rubber body, with polyester cords which contribute to its smooth operation and quietness. ZOOM Garage Doors recommends a belt drive opener for quiet, consistent and smooth operation.
Screw Drive Openers
ZOOM Garage Doors recommends a Screw drive garage door opener for larger or heavier garage doors. It operates by using a threaded rod that rotates, this assists the door in opening and closing. The screw drive opener is not as quiet as a belt drive opener, but not as loud as a chain drive opener. This type of opener requires less maintenance due to its simplicity.
