22.	The Forward L Countertop Support is a versatile bracket. It is also used in countertop island support applications. Most commercial cabinetry is made of particle board and is not suitable for directly attaching a bracket, corbel or other load bearing support. This means the inside - top - back wall of the cabinet will need to be reinforced or "gusseted" with a 2 x 4. To attach the gusset we typically use Liquid Nail as an adhesive and clamp the 2 x 4 in place until the adhesive dries. For more detailed instruction please see our installation guide for this countertop support bracket. Delete if not required.
