      Chain-driven operators are the oldest type of openers. They have a chain circling two metal sprockets, pulley connecting the chain from it both ends and that pulley pulls the door open or closed. This type of openers is very reliable, but with one disadvantage, they are louder than their belt or screw drive openers.!

      Screw drive units are also very reliable like the chain drive openers and too require regular maintenance treatment (oiling and greasing al of the moving parts at least once a year). Screw drive openers thou are indeed much quieter than the chain drive units.

      The belt driven openers are the ultimate choice for most of our customers. These units have no metal on metal contact, which makes them very quiet and maintenance free.
