Foldable clamp for a mounting system

A clamp, comprising:

• a rack having a plurality of spaced outer teeth and a plurality of spaced inner teeth;
• an upper jaw interconnected to said rack;
• a carrier operatively interconnected to said rack;
• a lower jaw interconnected to said carrier and spaced from said upper jaw;
• a spring-biased pawl rotatably interconnected to said carrier, said pawl having a first portion rotatably interconnected to said carrier and a second portion that is adapted to selectively engage a space between adjacent teeth of said plurality of spaced outer teeth;
• a pawl release associated with said spring-biased pawl, actuation of said pawl release removes said second portion from said plurality of spaced outer teeth;
• and
• a spring-biased crank rotatably interconnected to said carrier, said crank having an end that that is adapted to selectively engage a space between adjacent teeth of said plurality of spaced inner teeth, said crank being spring-biased such that release of said crank removes said second portion from said plurality of spaced inner teeth, wherein rotation of said crank moves said lower jaw incremetally towards said upper jaw, and wherein the distance between said upper jaw and said lower jaw is maintained by said spring-biased pawl that is moved along said outer teeth in a direction towards said upper jaw when said crank is rotated.
