Guide track assemblies and mounting brackets for upward acting doors

A guide track assembly for guiding movement of an upward acting door between open and closed positions, said guide track assembly including:

• a first substantially linear track section adapted to be mounted extending substantially horizontally;
• a second substantially linear track section adapted to be mounted extending substantially vertically adjacent a wall;
• a header bracket for mounting stationary with respect to said wall;
• a curvilinear track section extending between said first and second linear track sections, said curvilinear track section being engaged with and releasably connected directly at its opposite ends in supportive relationship to said linear track sections, respectively, and said curvilinear track section being engaged with and connected directly to said header bracket at a point between said opposite ends of said curvilinear track section;
• and
• at least one jamb bracket adapted to be connected to said wall and to said second track section to provide for supporting said second track section with respect to said wall.

• a header bracket for mounting on said wall;
• a curvilinear track section extending between said first and second linear track sections, said curvilinear track section including opposite end portions connected directly to respective ends of said first and second linear track sections, respectively, whereby said curvilinear track section is engaged with and releasably connected directly to said linear track sections in supportive relationship, respectively, and said curvilinear track section is releasably connected directly to said header bracket at a point between said opposite end portions;
• and
• at least one jamb bracket adapted to be connected to said wall and to one of said linear track sections for supporting said one linear track section with respect to said wall.
