Compatibility
Thanks to the adjustable design, this sink bracket suits most square undermount sinks or basins used in kitchens and bathrooms, and you only need to measure the height from the sink bottom to the floor to get the right fit.
Installation
Nothing needs drilling, the sink stays in place and the plumbing stays connected, so installation is quick and straightforward. A little movement while you set up is normal because there is no support point yet, and once the kit is properly installed under the sink the structure becomes highly stable.
