With a torsion type of spring, the energy is imparted or removed by rotating the spring clockwise or counter clockwise depending upon the direction of usage. With professional installation, the complete loading of the torsion spring is controlled by the garage installer, and is determined by the weight and size of the garage door that it is operating. When this type of torsion spring fails, it remains attached and intact to the location on the horizontal control rod where it was mounted. I have not heard of or seen any torsion spring fly across a garage, creating injury from failed components as with the stretched older style garage door springs. This is not to say that injuries have not occurred with the torsion style spring. The installation of this type of spring is generally safe when left to a trained garage door installation professional. Severe and serious injuries have occurred when untrained, unqualified individuals have attempted to install or service this type of spring.
An exception to this relates to "do it yourself" garage door kits that are sold at local home centers. A homeowner could install the door because these kits do not come with a professional quality package of hardware that should or would require special knowledge for the installation. These kits do not typically employ torsion springs that would require special knowledge, proper tools, and working skills to install. The doors are typically for light duty use. Professional installation services are often available through a home center to assist a homeowner in need of a specialized installation. As with most trade specific tasks, years of experience working as a professional installer qualifies tradesmen for their contracting license. The average homeowner watching a few television shows that give rough explanations of how to install garage doors is not usually qualified to install his or her own door. These "how to" television shows are no substitute for the many skills acquired after working in the field.
These doors can be chain driven either manually, or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently, and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door, as the weight of these type of doors is normally much greater than an overhead door.
Wayne Dalton, established in 1954, is the producer and supplier of the safest residential and commercial garage doors and garage door openers in the US. Wayne Dalton supplies two kinds of garage door openers: wall mount and ceiling mount. The wall mount openers, an exclusive product from Wayne Dalton, can be mounted on the wall beside the door. This helps to eliminate the chains, belts, screw drive and tract that usually clutter the garage ceiling. This model also helps to eliminate noise and vibration to a large extent.
