Portland Iron Corbel 3-Inch Wide

This information is provided by The Marble Institute of Americas published requirements for granite countertops.

What size corbel do I order?

• Your Countertop overhang should not extend past the corbel by more than 4 to 6 inches.
• Example: If your countertop overhang is 10-inches you will want a bracket that measures at least 5 to 6 inches deep.
• All our corbel measurements are listed as depth x height | Example: a 6" x 8" corbel is 6 inches deep and 8 inches high.
• Notes From a Designer: Corbels are meant to be seen. So they generally look best when they are 2/3 as deep as the countertop overhang itself. As an example, when we design countertop overhangs we will keep the end of the corbel 2-4" from the end of the countertop overhang. This does exceed the Marble Institutes requirements but it looks much better from a design perspective.

How many corbels do I order?

• Corbels are generally spaced 24 to 36 inches apart under countertop overhangs.
• To figure out how many corbels you need lets start with 2 corbels at each end of the countertop set 4" to 6" inches in, from the edge.
• Now measure the span left between the 2 end corbels and use the following formula: (span left) divided by (desired spacing).
• Example; an 84" wide countertop with 2 brackets set 4 inches from the end would leave you with 76 inches left to support; (84" - 8" = 76"). Now take 76" divided/by 24" = 3.1, so you would need 3 more corbels for a total of 5 brackets.
• For a countertop overhang spanning 84" wide with 2 corbels set in 4" from either side, and a 24 inch span between corbels, you would order 5 brackets total. 2 ends brackets and 3 to support the remaining 76" span.
• For a countertop overhang spanning 84" wide with 2 corbels set in 4" from either side, and a 36 inch span between corbels, you would order 4 brackets total. 2 ends brackets and 2 to support the remaining 76" span.
