Schluter-KERDI-LINE is a low profile linear floor drain specifically designed for bonded waterproofing assemblies. KERDI-LINE can be installed adjacent to walls or at intermediate locations in showers, steam rooms, wet rooms, and other applications that require waterproofing and drainage. The floor can be sloped on a single plane to KERDI-LINE, which enables the use of large-format tiles and creates interesting design opportunities.

Schluter-KERDI-LINE consists of a formed stainless steel channel body and a grate assembly that can be seamlessly adjusted to the thickness of the ceramic tile or stone covering from 1/8" to 1" (3 mm to 25 mm). The channel body features a standard 2" (50 mm) no-hub outlet and is attached to the pipe using an appropriate mechanical (e.g., flexible or no-hub) coupling. The simple connection to standard drain outlets makes KERDI-LINE suitable for new construction and renovation. KERDI-LINE is available with both center and off-set outlets. The off-set outlet is located 8" (20.3 cm) from the edge of the channel body and provides flexibility when obstacles (e.g., floor joists) are encountered during installation.

Schluter-KERDI-LINE includes a corresponding polystyrene foam channel support and can be installed in conjunction with the matching 8.8 Schluter-KERDI-SHOWER-L/-LS sloped trays with integrated Schluter-KERDI waterproofing or a sloped mortar bed covered with the 8.1 Schluter-KERDI waterproofing membrane. The trays are available for wall (-LS) or center (-L) drain placement. Surrounding walls are made waterproof using Schluter-KERDI or Schluter-KERDI-BOARD.

The perimeter of the channel body consists of a bonding flange laminated with a collar made of Schluter-KERDI. It ensures a simple and secure connection to the bonded waterproofing assembly, both in the floor area and on adjacent walls.

The grate assembly consists of a brushed stainless steel frame and three design grate options. Option A is a closed-design, brushed stainless steel grate. Option B is a brushed stainless grate with square perforations. Option B is also available with a locking mechanism (3/4" - 19 mm frame only) for applications where tamper resistance is desired or required (e.g., healthcare and education facilities, etc.). The covering support D is a stainless steel plate with Schluter-KERDI laminated on the surface to allow for bonding of ceramic or stone tile which creates a virtually invisible drainage line.

Schluter-KERDI-LINE is available in channel lengths from 20" to 72" (50 cm to 180 cm) in 4" (10 cm) increments. Please note that the bonding flange extends approximately 1" (2.5 cm) beyond the channel on all sides. The Schluter-SHOWERPROFILES/-R system profiles represent an elegant solution for finishing the area between the floor and the first course of wall tile in a way that eliminates cutting wedges of tile and ensures a consistent elevation of the first course of wall tile in Schluter-KERDI-LINE applications. Schluter-SHOWERPROFILE-S consists of a trapezoid-perforated anchoring leg with a groove, which accepts a tapered brushedstainless steel profile that matches the slope of the KERDI-SHOWER-L shower tray. The profile is adjusted to cover the exposed wall area and forms the visible surface. Schluter-SHOWERPROFILE-R consists of a brushed stainless steel profile and corresponding channel. The profile is adjusted to fit the space between the KERDI-LINE and the wall tile and forms the visible surface in applications where KERDI-LINE is placed adjacent to a wall.
