Attach two support studs to the top of cabinets at the back panel and where the end of the support bracket falls.

Use a router to cut a dado deep enough for the support bracket to lay flush with the top of the support studs. Be sure that the support bracket will be flush with the bottom of the countertop and the top of the stud. The bracket must make full contact with the bottom of the counter top.

Attach the Granite Counter Support Bracket to the support studs using a minimum of four screws. Screws should be a minimum of 1.5” long. Do not overhand more than 2/3 of the bracket. A minimum of 1/3 of the bracket must be mounted inside the cabinet. The countertop must be resting of the Support Bracket.

Brackets should be mounted every 16” for proper weight bearing effectiveness.

Overhang beyond the Support Bracket should not exceed 6”. Check with the counter manufacturer for their overhang recommendations.

Apply adhesive to both the counter top and the Support Bracket when mounting the counter top.
