Properly balanced door with operator


The horse power of a given electric operator is not an extremely important selection criteria. The balanced
weight of a commercial or industrial garage door will vary between 10 to 20 lbs. (5 to 10 kg) regardless of its size. It is important that the owner of the building be aware that the counter balance system (torsion springs) must be checked every 3 months in order to insure that nothing hampers the operation of the system.
