What is a Cheeseboro?

Cheeseborough clamps, also known as Cheeseboro, Scaffold Clamps, Couplers, Swivels, or even Cheese-burger or Burger Clamps, are devices used to connect iron pipes or aluminum tubes. The term is believed to originate from the Chesebro-Whitman manufacturing company in New York. These clamps are available in rigid (fixed 90°) or swivel styles for various rigging applications.
