French Cleat mounted parallel clamp mount. Holds 6 standard sized parallel clamps. Top edge has a 1/4" taper to the wall to prevent clamps from sliding off. (Although I've never even had that happen on my flat version.) I prefer a continuous taper verses a tab at the end that you will constantly slam when removing the clamps.
 
Made from 18mm thick, 13 layer, Russian Baltic Birch. Parts are straight off the CNC.
 
Includes CNC cut parts that you must glue together.
