A garage door cable drum is disclosed for a sectional overhead door of a type having a substantially non-linear lift-weight to lift-height characteristic. The drum includes a generally spiral cable groove having a variable minor radius. The groove minor radius at any intermediate point along the groove is sized to provide a lift-cable moment arm that yields a corresponding cable lift force that is slightly less than an instantaneous lift weight of the garage door at any intermediate door elevation.

Overhead door lift system

A garage door bottom seal retainer ( ) comprises a seal cavity ( ), a exterior tension member ( ), and an interior tension member ( ). In use, an installer slides a retaining member ( ) of a seal ( ) into the seal cavity ( ). Then the installer seats an exterior gripping edge ( ) of the exterior tension member ( ) upon an exterior shelf ( ) of a bottom surface ( ) of a garage door ( ). The installer then applies force to the interior tension member ( ) so as to seat an interior gripping edge ( ) into place upon an interior shelf ( ) of the bottom surface ( ). In this manner, the seal ( ) is secured to the retainer ( ) and the retainer ( ) is then secured to the garage door ( ) without the use of any tools or fasteners.
