Rabbet Joints
How are the cabinet backs secured?
Cabinet Back Sealing
We route a "rabbet" (L-shaped notch) into the back of the gables. The 1/2" or 3/4" back panel sits inside this notch, which squares the cabinet perfectly and prevents "racking" or leaning over time.
An L-shaped groove cut into the cabinet side to allow the back panel to sit flush and square the box.
