The Liberty hidden countertop support plate easily mounts to knee walls creating the ultimate floating counter appearance. Each hidden countertop support can hold an astounding 375 pounds, allowing you to safely mount thick granite, quartz, marble, other natural stones and concrete countertops. Route out the top of the knee wall for a flush mount hidden bracket that allows for plenty of chair and leg room. If the steel finish is selected, the bracket will arrive unfinished and will need to be painted or clear coated to prevent oxidation.

  • Sizes: 8" to 20" (this is the support measurement, plate will be 4-1/8" longer for mounting)
  • Finishes:  Raw Steel and Flat White.
  • Material Thickness - 1/4”
  • Holes: 8" to 12" (2) .50" Countersunk Holes, 16" to 20" (3) .50" Countersunk Holes
  • Carry Capacity:  375 Pounds per bracket.
  • Note: Raw steel does require a finish such as painting, plating or galvanizing in order to inhibit rusting. (See video link on how to paint a bracket)
