Noble Company has been awarded U.S. Patent No. 7.632.401 for NobleFlex® Drain Flashing. Patents provide recognition, from a very discerning source, that a product is unique. NobleFlex Drain Flashing had the requisite innovative features. It facilitates the use of a standard clamping ring drain with NobleSeal sheet membranes (and other ANSI A118.10 waterproofing membranes) and is an alternative to integrated bonding flange drains.
The Flashing provides a smooth transition between the NobleSeal® and the weep holes in a clamping ring drain. The design allows tile to meet the top of the strainer. It is easy to use and has been installed in showers throughout the USA.
