Minimum of 2-Brackets
Set Brackets 12″ from each end of Top and then every 16″ to 24″ on center
Calculator: Number of Brackets= (Length divided by 24″) + 1-Bracket
Please note that when it comes to ledges on knee wall or half wall, generally speaking, the 2/3rd rule does not apply, and bracket support are almost always needed.
Note: Additional brackets may be needed due to the amount of overhang and fragility of the material as determined by the Lang Stone Drafting or Installation Team. When working with Lang Stone there is no requirement as to who supplies and/or installs countertop brackets.
