Techno Flange® Closet Flanges

Product Description and Features

The Water-Tite Techno Flange Standard Pattern Closet Flange with Techno Knockout features an inset test cap that cannot be damaged by construction equipment, ensuring drain lines stay securely covered and protected until installation and DWV (drain, waste, and vent) testing are complete. The Techno Knockout is specially designed to break out in one piece and will not fall down the drain line while it is being removed. Compatible with both 3- and 4-inch Schedule 40 DWV pipe, this ABS toilet flange has a Flush-Tite design that allows for flush installation inside of 4-inch pipe. It also features a beveled hum, which makes it easier to insert into 4-inch foam-core pipe.
