2′ x 8′ Jack


  • This is a triangular frame used to brace and provide lateral support to flats.
  • Jacks can be built in a variety of shapes and sizes
  • This particular jack was designed for those who do not have access to miter saws (to cut angled pieces).
  • Jacks are typically placed behind flats and screwed to the frame of the flat. The base is either screwed to the floor or weighted. These are re-used from set to set, so glue is not used to attach the jack to the flat.
  • However, glue is used within the unit when building it.
  • This jack measures 2’ x 8’ and is made out of 1 x 3 pine, ¾” x 5” pine, and ¼” Luan.
  • Please note that when dimensions of lumber are given, the actual size will be followed by an inch (1”) or foot (1’) mark, while the nominal size will not.
  • Example: Nominal size = 1 x 3 vs Actual size = ¾” x 2 ½” (Learn more here)
  • Always check for square!
