Single Panel Garage Door Opener - As a door expert witness, I'm called upon many times per year to gauge garage door injuries. Garage doors come in many sizes and shapes. Their functions range from fundamental security of an area to concealment that is cosmetic. Most doors could be broken down into several basic styles or groups. Typical contemporary garage doors for residential applications are usually mainly of the overhead sectional variety. That style of the door comes in amounts of insulation, many configurations, substances, and a broad array of appearance options.
They are accessible as a prefabricated kit or assembled as a custom layout to complement the decor of any building. Commercial warehouse kind installations frequently dictate higher security requirements. A good option with this security type of door is the "roll-up" style that resembles a roll top desk type of door. This door may be produced using a variety of stuff that may be as sturdy as the abutting walls, making forced entry by means of this opening very hard.
In the past, with running an overhead garage door, the biggest concern was the potential hazards associated with the springs used for balancing the door weight. Pre mid-1960's garage door installations generally relied upon a set of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. Unloading (releasing) of the stored spring energy occurred as the door was opened to the flat overhead location.
One of the very most dangerous aspects of these spring systems was that after a period of time, frequently with no maintenance or review, the points of attachment of these springs would rust or become feeble. This weakening of points or the springs of attachment would frequently lead to an inadvertent explosive failure fling the spring that is broken components over the garage, embed the spring or steel components to the garage walls, alternative things in the path of travel or cars.
