Adjustable running board

A running board having an adjustable length, comprising:

• an elongate deck;
• a rigid support frame disposed in underlying relation to said elongate deck;
• a first end-cap disposed at a first end of said elongate deck;
• said first end-cap being integrally formed with said elongate deck and said rigid support frame;
• a second end-cap disposed at a second end of said elongate deck;
• said second end-cap being independently formed with respect to said elongate deck and said rigid support frame;
• a mounting shoulder disposed in underlying relation to said second end-cap and extending a predetermined distance from thereunder relative to an upper inner edge of said second end-cap;
• a longitudinally disposed, downwardly opening alignment channel formed in said rigid support frame, said alignment channel slideably mating with a longitudinally disposed alignment ridge formed in said mounting shoulder,
• said mounting shoulder adapted to support a second end of said elongate deck and said rigid support frame;
• said elongate deck and said rigid support frame being formed of a cuttable material and being cuttable to any preselected length;
• said mounting shoulder disposed in underlying, supporting relation to said rigid support frame and hence said elongate deck after said rigid support frame and elongate deck have been cut to a predetermined length;
• whereby said second end-cap performs both a decorative function and a structural function;
• and
• whereby said second end-cap enables said running board to be cut to any preselected length without loss of aesthetic or structural integrity.
