Determine What Size & Quantity to Order?

What Size Bracket Should I Use?

  • NOTE: Ideally you want no more than 3" of unsupported countertop extending past the end of your bracket.
    • Example: If your countertop overhang is 19” Deep (19” – 3” = 16”) You’d want to go with an 16” x 12” Bracket
  • Our brackets are listed as follows, depth x height measurements
    • Example: 10” x 8” Bracket
      • 10” would be supporting your material (horizontally or depth)
      • 8” would be mounted to the wall (vertically or height)

How Many Brackets Do I Order?

  • These countertop support brackets are typically spaced 16 - 24 inches apart, or 1 bracket on each framing stud.
  • To figure out how many brackets you need lets start with 2 brackets at each end of the countertop set 4" - 6" inches in from the edge.
  • Now measure the distance between the 2 end brackets and use the following formula:
    • (Distance Between) divided by/ (desired bracket spacing).
    • Example 76 / 16 = 4.75, so you need 4 more brackets to support the space left between the two end brackets.
  • Here is an example using a real countertop installation:
    • An 84" wide countertop with 2 brackets set 4 inches from the end would leave you with 76" left to support; (84" - 8" = 76"). Now take 76" divided by / 16" = 4.75, So you would need 4 more brackets for the space left giving you a total of 6 brackets for this project.
  • For a countertop overhang spanning 84" wide with 2 brackets set in 4" from either side and a 16" span between brackets, you would order 6 brackets total. 2 end brackets and 4 to support the remaining 76" span.
