Size & Quantity Guide
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" divided 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.

"The 2”x 1/2” steel countertop supports work great. Easy to install and provide amazing countertop support. I ordered white to blend in with the white quartz countertops. I ordered about 5 inches shouter the counter so they are invisible. Will order again."

Answer to Prayer
"Our contractor thought 3/4 inch plywood with 1/4” thick & 2” wide strips of steel to go underneath LED panels (that can not be glued) was going to be adequate to support 111”x 67” island with an “L” shape overhanging sitting area for our Quartzite Crystallo Slab. We weren’t taking chances with the stone & were very uncomfortable with the flex of the sub-deck. Enter Iron Support to the rescue!! Iron Support answer our prayers of worry!! We retro installed support (3 long straight supports & 2 - “L” support under the sub-deck notched into the cabinets. The support is much improved!! 🥳 P. S. Ordered Wednesday & got to us Friday, expedited! Thank You! ❤️"

Q&A
- If I have a 26in cabinet, can I have a 21in overhang with theses brackets?
- Yes, for a 26" cabinet with a 21" overhang, we recommend using our 44" Deep Hidden Island Countertop Bracket. This size will provide the proper support needed for your countertop overhang.
- Is the length of bracket true to the specified size? i.e. is the a 20in bracket actually 20in in total length? I want to confirm so I can account for the thickness of the cabinet walls the bracket will be screwed into. Thanks
- Yes, the bracket length is true to the specified size. For example, a 20" bracket measures 20" in total length. This allows you to accurately account for the cabinet wall thickness when planning your installation.
- Hello - I have an L shape island, but want to install a square countertop. The long end is 62" and the short end is 25" so the countertop would extend another 37" past the cabinet there. How many brackets would you recommend and placement? Thank you, T
- These island countertop support brackets are typically spaced 18 - 24 inches apart.
- Will these brackets work with MDF cabinet boxes?
- Yes, it will work.
- Hello, I would like to have 12" overhang on 1 sides of my island and 10" on the other two sides. The cabinet size is 81" long x 24" deep base unit. One overhang of 12" on the 36" length and 2 10" overhangs on the 24" ends. How long do my brackets need to be? How far back from the end of my quartz countertop can I go? How many brackets will it need on each side? Will I need to add an extra, angled (45 degree), support on the 2 corners where the 2 overhangs meet?
- Hi, we recommend you get the four (4) Hidden Granite Countertop Flat Bracket (https://ironsupports.com/products/hidden-granite-countertop-flat-bracket) on the shorter side, two (2) brackets on each end and four (4) 36" Hidden Island Countertop Bracket (https://ironsupports.com/products/hidden-island-countertop-bracket) on the longer side. To determine the size of the flat bracket, here's the link you can use for your reference - https://ironsupports.com/products/hidden-granite-countertop-flat-bracket#determine-what-size-quantity-to-order. And to support the corner, you'll just need to install the brackets closer together.
