A unique pair of clamps on the Richeson Wet Canvas Carrier allows two canvases of any size to be transported whilst still wet. The top unit comes complete with a hand carry handle and attaches via an adjustable clamp and the lower unit is then attached to the lower edge. Then clamp a similar size, wet or dry, canvas to the other side with the wet surfaces facing each other and so keep the canvases 15mm apart. When not in use, the clamps fit easily into the bottom of the sketch box.
