Caiman® Undermount Sink Bracket

Caiman® Under-Counter Sink Mounting Systems was invented by countertop installers looking for a better way to mount under-counter sinks.  This product was developed specifically for installers to speed up the sink installation process and guarantee longevity.  This is especially important when mounting a cast-iron sink that can weight up to two hundred pounds plus!  The under-counter sink mounting system will give your customers confidence in knowing that their sink will not fall out, and will help their productivity as it is simple to use.


  • Easy to install, takes less than ½ the time of traditional sink brackets
  • Able to easily support the heaviest of under-counter sinks with a weight rating of 250 pounds
  • Built of rolled 1/8” galvanized steel for superior durability and longevity
  • Designed to fit any cabinet size between 20” – 26”
  • Designed for use with both single and double sinks
  • Built with a patented center-bracket design for guaranteed durability and quick installation
  • Each bracket has four threaded bolt positioning holes to fit the needs of almost all sink types
  • Each set includes a set of easy to follow instructions

  • 2 – sink mounting brackets (A)
  • 4 – 3 ½” #14 fine threaded bolts (C)
