Countertop Support Brackets used on granite countertop

Granite Brackets and Countertop Brackets by Centerline add hidden support for overhangs, center-levered bar tops, kitchen islands, shelves and more.

Countertops made from granite, marble, quartz, Silestone, Corian and even heavy butcher block are becoming very popular. Kitchen designers and homeowners are pushing the structural limits of these solid surface materials as they become aware of new trends and materials available to them. Accordingly, Centerline Brackets specializes in manufacturing high quality countertop supports designed to safely support and bracket commercial and residential applications.

Countertop Brackets by Centerline Brackets are part of this new movement. Our countertop support brackets are the gold standard in countertop brackets and used in thousands of kitchens across the country. Traditional supports such as wooden corbels, standard legs and typical angled braces are giving way to “Hidden” Granite Brackets giving your kitchen a more spacious design.

Frequently asked questions

What length granite bracket will you need? Typically the bracket will be the same length as the overhang.

  • The drawing below shows a 96 inch countertop with a 16 inch overhang past the knee wall. 20 inches total.
  • The length of the bracket should include the width of the knee wall. In most instances the knee wall is 4 inches wide. The overhang plus the knee wall = 20 inches.
  • Granite Brackets should be set three - four inches back from the edge of the granite counter top to insure they are hidden from view. So - 20 inches - 4 inches = 16 inch brackets.
  • If your knee wall is made from 2 x 6s then be sure to adjust your size to accommodate the extra 2 inches.

Countertop Bracket Layout

How many granite brackets will you need?

  • Countertop brackets are generally spaced 18 - 24 inches apart.
  • Start with a bracket at each end of the countertop set 4 - 6 inches away from the end.
  • Now measure the space left - in this instance we have 96 inches minus the the placement of the first two brackets placed 6 inches from the edge along with the width of the brackets (2.5 inches each) for a total of 79 inches left.
  • 79 inches divided by 24 inches = 3.2 brackets. 3 granite brackets would be required for the space left.
  • Countertop Length = 96 inches
  • A bracket will be placed 6 inches in from each side
  • The remaining space to support is calculated at 79 inches (96 inches - 12 inches (space from ends) - 5 inches (brackets width) = 79 inches)
  • 79 inches divided by 24 inches = 3.2 brackets
  • Order two granite brackets for the ends and three granite brackets for the middle for total of five countertop brackets.
