The holding arms are spring loaded and will hold your desired surface from the sides at a minimum of 5 inches horizontal. The arms can easily be adjusted to hold a much larger piece. The horizontal holding capacities are listed below for each size.
8 x 10: 5 inches to 15.5 inches (horizontal)
10 x 12: 5 inches to 17.5 inches (horizontal)
11 x 14: 5 inches to 19.5 inches (horizontal)
12 x 16: 5 inches to 24 inches (horizontal)
There is not any vertical limitation to panel/canvas height when using our original and patented spring arm design.
MAIN PALETTE MIXING AREA
We use the highest quality of Baltic Birch for the palette mixing area. We offer four different palette sizes to choose from. The palette mixing area is listed below for each size.
8 x 10: 9 15/16" L X 7 3/16" W X 5/8" D
10 x 12: 12 5/8" L X 8 3/8" W X 5/8" D

12 x 16: 17 1/8" L X 12" W X 7/8" D
Every Palette/Panel Holder that has been made by Open Box M since 1989 will have the regular 1/4 inch, 20 thread count tripod fitting that is located on the underside of the palette. This is the same fitting that is found on the underside of most cameras and this is the fitting that allows the device to be attached to any regular, sturdy camera tripod.
SIDE PALETTE EXTENSION
Every Palette/Panel Holder comes with one Side Palette Extension that can be attached to either the right or left side of the main palette mixing area. The extension serves as a shelf for brushes and palette knives and also can be used for more mixing area. We supply Front Palette Extensions and additional Side Palette Extensions for more shelf space and mixing room.
SIDE SUPPORT ARM
Our patented and adjustable Side Support Arm slides to the rear to give solid support to the panel holding surface. Unlike "torque" or "friction" hinges, the Side Support Arm will not move once it is engaged. The arm will easily adjust from an angle of 90 degrees to completely flat and will always give very solid support (when used correctly), even after many years of use.
