Whitehaus Collection created this Undermount Installation Kit to help with added support for Fireclay Sinks. Under-mount support bars install by Whitehaus just like closet poles horizontally under the sink. The escutcheon pieces screw directly into the cabinetry. Slide the bar into the round escutcheon and then drop the bar into the cupped escutcheon. It is ideal for residential and hospitality applications. You don't have to worry about sink support and space under the entire sink.
This kit makes it quick and easy to install your new undermount sink. It consists of two 36" white metal rods that can be cut to fit the inside width of your cabinet. They mount onto the cabinet walls with the 4 metal flanges and screws supplied in the kit. The sink then sits on the rods which support it from beneath and secure it in place.
