This undermount sink support kit delivers up to 500 lb of stable, load-bearing reinforcement for undermount sinks in kitchens and bathrooms.
Crafted with stainless steel tubes, a thick metal base, and non-slip protective pads, this two-bar system strengthens and steadies loose sinks and can also bear heavy items such as fish tanks, shelves, cabinets, and other equipment.
The assembly is height adjustable to fit most square undermount sinks or basins.
Before you install, measure the distance from the bottom of the sink to the floor to confirm a proper fit; installation requires no drilling, and there is no need to remove the sink or disassemble plumbing. A little movement before final tightening is normal, but once correctly positioned under the sink, the structure becomes highly stable.
Beyond supporting sinks, this versatile bracket system provides reinforcement for shelves, cabinets, and other heavy household items.
