Definition
An opener that moves the trolley along a long threaded steel rod instead of a chain or belt. With fewer moving parts, screw drives need little maintenance beyond occasional lubrication, and they are quick. Their weakness has historically been temperature sensitivity — big hot-to-cold swings, which the Four-State Area delivers every year, can make older screw drives sluggish or noisy without the right lubricant. They have become less common, but Door Serv Pro still services them and can advise when replacement beats repair.
