Never knew such a thing existed !!!! I’m assuming they are quieter as well ? Or not so much? Also does it have the same type of plastic worm gear that the standard chain drives have had for decades, the ones that are susceptible to heavy wear if not periodically regreased and spring tension tightened properly for to eliminate overworking ?

Extremely quiet and requires zero maintenance! Lock to the shaft and you’re good to go!

Emergency opening possible?

Yes, it has a release cord that hangs from the bottom of the unit.
