ABSTRACT:
An upward acting sectional door formed of rectangular door sections which are interconnected to form a closure over a door opening. Opposed somewhat L-shaped bottom brackets are secured to opposed lower side edges of the bottom door section by fasteners which are not easily accessible for removal when the door is assembled and disposed between adjacent guide tracks. Opposed guide rollers connected to counterbalance cables are partially supported by the brackets and transfer upward lifting forces to the door through the brackets.
