A method for treating wood products comprising:
- providing a plurality of wood products having two opposing ends;
- providing an open-topped tank having therein a treating liquid at ambient temperature and pressure;
- providing a clamp panel suspended above said tank, said clamp panel having two opposing clamp boards, each one of said two opposing clamp boards having two opposing ends, said two opposing clamp boards being rigidly disposed on said clamp panel with a crossbeam extending therebetween and connected to each of said clamp boards at about, said crossbeam being movably attached to a frame and said opposing ends of said two opposing clamp boards being four corners of said clamp panel;
- placing said plurality of wood products in a German stack, said German stack having a top end comprising two wood products in said plurality of wood products disposed on opposing edges of said top end, said two opposing ends of said two opposing wood products in said German stack being four corners of said top end of said German stack;
- pressing said clamp panel against said top end such that said four corners of said clamp panel contact said four corners of said German stack, applying downward pressure on said German stack and inhibiting shifting of said German stack;
- submerging said German stack in said treating liquid;
- during said submerging step, maintain said downward pressure on said German stack with said clamp panel and thereby stabilizing said German stack in said treating liquid.
