About this product


  • Ideal for supporting overhangs where you don't mind brackets being visible 
  • 1/2"-thick heavy-duty American steel, 2-1/2” wide (click thumbnail image to view a drawing)
  • Durable powder-coated finish in black or white; or choose raw steel (must be finished to avoid oxidation)
  • 7 sizes from 8"L x 6"H to 20"L x 14"H
  • Screws (included) secure brackets to lumber inside cabinet base
  • End of horizontal section is beveled for safety 
  • Carrying capacity is 325 lbs. per bracket

Important Notes

  • Select a length that will leave no more than 4" to 6" of overhang unsupported.
  • Brackets should be spaced no more than 16" to 18" apart, center on center.
  • Installation requires securing brackets to lumber inside base cabinet.
  • A countersunk hole is drilled into the underside of each bracket, 1.5” in from its end (see last thumbnail image). A 1.25”-long screw is provided. These holes and screws help secure the wood top to the brackets and prevent bowing. The screw's diameter is small enough to allow for wood expansion & contraction.


Visible Support Brackets for Cantilevered Islands and Countertops

These sturdy L brackets are designed to support kitchen countertop and island top extensions or overhangs. Simply array the brackets, 2-1/2 inches wide, spacing them no more than 16 to 18 inches apart. Incredibly strong, these L brackets will provide ample support so that diners can enjoy meals, snacks and drinks while comfortably seated at your kitchen island bar.

The installation process is straightforward. Simply use the screws provided - 3 per bracket - to secure each bracket to a vertical stud in the island's frame.    

These L Brackets Come in Many Sizes and Multiple Colors

Choose among two powder-coated options - white or black, or select raw steel if you prefer to paint your brackets, perhaps to match the color of your island's base.

In order to ensure adequate support of the cantilevered portion of your island or counter top, be sure to order brackets of a length (front-to-back) that will leave no more than 4 to 6 inches of the extension unsupported. With 7 different sizes to choose among, you should be able to find one that fits your new construction or remodel project.
