Pochade Box, Artists Adjustable Easel and Palette Box (CT-PB-0910) – Medium. The pochade boxes are built with strong finger joint construction using, poplar, maple, and Baltic birch components. A beautiful cherry stain and lacquer finish transform these painting tools into pieces you will treasure. All adjustments of the canvas holders and lid angle arm are controlled with easy to adjust plastic star knobs. Far superior to the common wing nuts found in many plein air easels the star knobs are easy to grip and result in much tighter holding power. The Medium pochade box include a removable tempered glass palette ideal for oils and acrylics. The finish provides an easy to clean finish and the light birch color is good for color mixing. The canvas holders are designed for ease of use and versatility. Both panels and stretched canvas can be held between the holders. Two star knobs in the rear of the lid adjust the height of your canvas. The maximum height of the M box is 15 inches; the L box is 17 inches. Any width within reason can be accommodated on both boxes. The included brush tray is a pleasure to use. It stows away perfectly on the back of the lid with the help of two magnets. During painting it slips over the right side of the palette box and stays put with another pair of magnets. T are indents for seven brushes and a flat area for holding palette cups of painting medium or thinner.
