Fixturing apparatus

A fixturing apparatus comprising:

• a housing defining an interior space and comprising a trapezoidal cross-section, a first end, and an opposing second end, and is formed to include an aperture extending therethrough from the first end to said second end;
• and
• a plurality of first locking teeth locking teeth disposed within said aperture;
• and a second plurality of locking teeth disposed within said aperture;
• wherein said housing comprises a first and a second assembly, each assembly comprising a bottom, a first lip extending outwardly from said bottom, an opposing second lip extending outwardly from said bottom, a first side wall extending outwardly from said bottom and connecting a first end of said first lip and a first end of said second lip, a second side wall extending outwardly from said bottom and connecting a second end of said first lip and a second end of said second lip, and said first plurality of locking teeth extending outwardly from said bottom, wherein said plurality of locking teeth are disposed between said first lip, said second lip, said first side, and said second side;
• wherein:
• said first side wall and said second side wall comprise a first height where said first side wall and said second side wall are attached to said first lip;
• said first side wall and said second side wall comprise a second height where said first side wall and said second side wall are attached to said second lip;
• each of said first plurality of locking teeth and each of said second plurality of locking teeth comprise a third height;
• said third height is less than said first height;
• said third height is less than said second height;
• and
• said first assembly is attached to said second assembly to form said housing.
