Support bracket and track assembly for sectional overhead doors

A fastening system for joining bracket and track components for sectional overhead doors comprising:

• first and second components to be joined;
• a tab extending from said first component;
• said tab including a pair of arms;
• an ear extending from each of said arms;
• said second component having a tab slot, said tab slot having an inner slot surface;
• said tab slot including a substantially circular aperture interrupted about its circumference by a pair of opposed rectangular notches;
• said tab being insertable into said slot when said ears are aligned with said notches;
• said first component being rotatable with respect to said second component such that said arms frictionally engage said inner slot surface and said ears frictionally engage said second component to frictionally lock said first component to said second component.

A fastening system for joining bracket and track components for sectional overhead doors comprising:

• first and second components to be joined;
• a tab extending from said first component;
• said tab including first and second arms angularly extending from said first component, said first and second arms being joined along a common edge to form a saddle;
• first and second ears extending perpendicularly from said first and second arms, respectively;
• said second component having a tab slot;
• said tab slot including a generally circular aperture interrupted about its circumference by a pair of opposed semi-circles;
• said tab being insertable into said slot when said ears are aligned with said semi-circles;
• said first component being rotatable with respect to said second component such that said tab frictionally engages said second component to frictionally lock said second component to said first component.
