What length granite bracket will you need? Typically the bracket will be the same length as the overhang.
- The length of the bracket should include the width of the knee wall. In most instances the knee wall is 4 inches wide. A 16″ overhang + a 4″ knee wall = 20″.
- Granite brackets should be set three to four inches back from the edge of the granite countertop to ensure they are hidden from view. 20″ – 4″ set back = 16″ support brackets.
- If your knee wall is made from 2 x 6s then be sure to adjust your size to accommodate the extra 2 inches.
How many granite brackets will you need?
- Countertop brackets are typically spaced 18-24″ apart.
- Start with a bracket at each end of the countertop set 4-6″ away from the end.
- Now measure the space left – in the example picture above we have 96″ minus the placement of the first two brackets placed 6″ away from the edge along with the width of the brackets (2.5″ each) for a total of 79″ left.
- 79″ divided by 24″ = 3.2 brackets. 3 granite brackets would be required for the space left.
- Order two granite brackets for the ends and three granite brackets for the middle for a total of 5 countertop brackets.
