About this product


  • Ideal for islands with double overhangs requiring support on both sides of a knee or pony wall
  • 1/2"-thick heavy-duty American steel, 2-1/2” wide
  • 16 lengths from 14"L to 44"L
  • Vertical flange (straddle) is 3.6"W x 4"H 
  • Durable powder-coated finish in black or white; or choose raw steel (must be finished to avoid oxidation)
  • 6 wood screws (included) secure bracket to 2x4s in support wall (see thumbnail image #2)
  • Ends of horizontal brace are beveled for safety

Important Notes

  • Designed to straddle any knee or pony wall's 2x4 frame, exclusively.
  • Select a bracket length that will leave no more than 4" to 6" of the overhang unsupported.
  • Brackets should be spaced no more than 16" to 18" apart, center on center.
  • Installation requires routing out sections (2-1/2"wide x 1/2" deep) of the wall's top 2x4 for flush mounting. See thumbnail image #3. 
  • Two countersunk holes are drilled into the underside of each bracket, 1.5” in from its ends (see thumbnail image). 1.25”-long screws are provided. These holes and screws help secure the wood top to brackets and prevent bowing. Screw diameters are small enough to allow for wood expansion & contraction.


Center-Mount Support Brackets for Double-Cantilevered Islands

These virtually-invisible brackets are designed to support both extended sides of a T-shaped kitchen bar island bar. With an array of brackets secured to the top of the island bar's 2x4 frame, you can ensure the top's weight will be securely supported. These are the center-support brackets that professional island makers and remodeling contractors prefer for supporting kitchen islands with not just one, but TWO otherwise-unsupported extensions.  

The installation process is fairly simple. First, notches 2.5" wide x .5" deep must be cut into the base frame's top 2 by 4. One support bracket will be nested into each cutout and secured to the base frame using screws that are provided.      

Center-Mount Support Brackets Come in Many Sizes and Multiple Colors

Since a portion of each bracket will be visible to someone looking at the underside of the island top from below, these otherwise-hidden brackets are available in three different colors. Black and white brackets are powder-coated for added durability. Raw steel is a good choice for those who prefer its look, or intend to paint the brackets, regardless.

In order to ensure adequate support of both cantilevered sections of your island bar, be sure to order brackets of a length that will leave no more than 4 to 6 inches of the countertop unsupported. With 16 different lengths to choose among, you should be able to find a size that fits your new construction or remodel project.
