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.
  • These brackets mount to the inside of your cabinet face and extend out past the cabinet base on the countertop overhang side.
  • Let say you have a 15 inch overhang with a 32" cabinet base, (15" + 32" = 47"). Now subtract 3" (this is the ideal amount of countertop hanging past the bracket), 47" - 3" = 44".
  • This is what the math for this looks like: (15" + 32") - 3" = 44"
  • Results: You would want to order a 44" island bracket.

How Many Brackets Do I Order?

  • These island countertop support brackets are typically spaced 18 - 24 inches apart
  • 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 / 18 = 4.2, 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" dived by / 18" = 4.2, So you would need 4 more brackets for the space left giving you a total of 5 brackets for this project.
  • For a countertop overhang spanning 84" wide with 2 brackets set in 4" from either side and a 18" span between brackets, you would order 6 brackets total. 2 end brackets and 4 to support the remaining 76" span.
