Roller Garage Door Brush Seal - Garage doors come in several shapes and sizes. Their functions vary from basic security of a place to cosmetic concealment. Most doors might be broken down into several basic styles or groups. Typical modern garage doors for residential uses have a tendency to be predominantly of the overhead sectional variety.

Before, with managing an overhead garage door the biggest concern was the potential risks associated with the springs used for balancing the door weight. Pre mid-1960's garage door setups commonly relied upon a set of stretched (tensioned) springs to help 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 position.
One of the very dangerous aspects of the spring systems was that after an amount of time, often with no care or inspection, the points of attachment of the springs would corrode or become feeble. This weakening of the springs or points of attachment would often result in an inadvertent volatile failure fling the spring that is broken components over the garage, embed the steel or spring components into the garage walls, cars or other items in the path of travel.
