Hidden Granite Countertop L Bracket

What Size Bracket Should I Use?

• NOTE: Ideally you want no more than 3" of unsupported countertop extending past the end of your bracket.
• Now, lets figure out what size bracket you need. Take the depth of your countertop overhang, in this example we will use a 15" overhang. Now add the depth of your knee or pony wall framing, which will be 4" to 6" depending on framing material used. 15" overhang + 4" framing = 19" total depth. Now take 19" and subtract 3", this is the amount of countertop that will overhang past the end of these brackets. 
• This is what that math looks like: (15" + 4") - 3" = 16"
• Results: You would want to order a 16" bracket.

How Many Brackets Do I Order?

• If you are going to be mounting these to a framed Knee or Pony wall it is advised that you put one bracket on top of each stud 16 - 24" apart. So you would order the same number of brackets as you have studs in the framing under your countertop.
• If you are mounting these to a header like on a reinforced cabinet base we advise you still mount them either 16 or 24 inches apart.
• Lest calculate the number of bracket you would need if you are mounting them to a header style framing.
• 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 3 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.
