Abstract: A trench drain defining a channel and having an accessory rib allowing the convenient attachment of accessories to the sides of a drain in order to facilitate the installation of a trench drain, place drain outlets at any convenient places along the trench drain, and to create right angle joints between two trench drains.

Abstract: A floor drain assembly for connecting to a drain system of an installation site. The floor drain assembly includes a drain body having drain coupling adapted for connecting to the drain system, a collar mounted to the drain body, and a rough-in adapter having a radially extending flange. The rough-in adapter is axially adjustably mounted to the collar and a strainer frame is axially adjustably mounted to the rough-in adapter. Mounted to the frame is a strainer. A cover encloses the strainer and strainer frame and includes a central region and a downwardly extending perimetric wall that is removably mounted, at a lower end thereof to, the flange of the rough-in adapter.

Abstract: A threshold drain for collecting an incoming flow of water. The threshold drain includes a catch pan having sidewalls, end walls, a bottom wall and an open top. The catch pan having a width defined between the sidewalls, a length defined between the end walls and a depth defined between the bottom wall and the open top. A grate received within the catch pan and extending between the pan sidewalls. The grate includes a louver array portion and an inlay tray portion. The louver array is configured to permit water to pass into the drain. The inlay tray portion is configured to receive a flooring material.

Abstract: A strainer for a floor sink and a floor sink strainer assembly. The strainer includes a central body defining a perimeter and further includes a generally planar flange extending outwardly from the perimeter of the body. The flange has a shape and size corresponding to the size and shape of the bottom wall of the floor sink. As a result, the strainer is constrained from lateral movement and lifting during a high influx of water.

Abstract: A U-shaped trench drain channel and system. The drain channel includes a body having an elongated length between opposing ends. The body further has two side walls, a bottom wall connecting the two side walls and an open top configured to receive a grate. Provided on an exterior surface of the body is at least one U-shaped reinforcing rib with a groove formed therein.

Abstract: Embodiments have an accessory rail along the length of each side of a trench drain channel. The accessory rib allows the convenient attachment of accessories to the sides of a channel in order to facilitate the installation of a trench drain, place drain outlets at any convenient place on a channel, and to create right angle joints between two trench drains.

Abstract: An exemplary embodiment providing one or more improvements includes an assembly which fixes and supports a floor drain at the appropriate position before a concrete floor is poured. The assembly is adjustable for floors of varying thickness. The lower or second end of the drain pipe is protected against contamination by wet concrete by a resilient disk. In addition a cavity on the bottom of the floor concentric with the drain pipe is formed. After the concrete floor has hardened and the form removed the resilient disk is removed exposing a clean uncontaminated drain pipe end for connection to a riser pipe.
