Countertop Island Supports are a great choice for supporting heavy countertops such as granite, quartz or butcher-block in an application where no knee wall exists and the countertop extends directly off the base cabinets.
The Countertop Island Support is a solid ½ inch by 2 ½ inch steel bar that runs through the base cabinet (see the image above) and extends to the length of the overhang minus a couple of inches to keep the countertop support hidden from view. The countertop support has a small 1 inch vertical flange on the back that mounts via two screws (the screws are provided with the countertop support) to the inside of the cabinet face frame. The flange is short, hidden from view and does not interfere with the operation of the drawers. The countertop support then runs through the cabinet and rests in a ½ x 2 ½ inch notch in the back side of the cabinet.
Before the countertop is mounted we suggest that the installer apply a bead of “Liquid Nail” on the top of the countertop support.
Once mounted the countertop support creates a cantilever, leveraging the weight of the countertop as well as the ½ inch steel. It’s a great bracket and perfect for most Countertop Islands.
