4" (100 mm) -square version only. Please
note that grate assemblies included with
the plastic KERDI-DRAIN featuring 3" (75
mm) outlets and the residential adaptor kits
only allow vertical and tilt adjustment (no
lateral adjustment). The covering support
is a 4" (100 mm) -square stainless steel
plate with KERDI laminated on the surface
to allow for bonding of ceramic or stone tile,
which creates a virtually invisible drainage
line.

-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. 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.
KERDI-LINE consists of a formed stainless
steel channel body and grate assembly or
covering support to which tile is applied.
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. The grate assembly 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 covering support
is placed flush with the top of the channel
body and can therefore accommodate any
thickness tile covering.
KERDI-LINE includes a corresponding
polystyrene foam channel support. The
perimeter of the channel body consists of a
bonding flange laminated with a collar made
of 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 two 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 KERDI waterproofing membrane
laminated on the surface to allow for
bonding of ceramic or stone tile, which
creates a virtually invisible drainage line.
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.

-KERDI-LINE-FC is a stainless
steel cover plate for use with KERDI-LINE
to create a seamless look in applications
where multiple drains are installed end-to-
end. KERDI-LINE-FC features a brushed
finish, and is designed for use with either
the solid or perforated grates with brushed
stainless steel frame.

-SHOWERPROFILE-
S/-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 KERDI-LINE
applications. SHOWERPROFILE-S consists
of a trapezoid-perforated anchoring leg with
a groove, which accepts a tapered brushed
stainless 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.
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 the KERDI-LINE is
placed adjacent to a wall.
Material Properties and
Areas of Application
KERDI-DRAIN drain casings are formed
using ABS, PVC, or stainless steel 304
(1.4301 = V2A). Plastic drain casings feature
a polypropylene fleece webbing. The KERDI-
DRAIN adaptor kits feature adaptor rings
made of stainless steel 304 (1.4301 = V2A)
with thermoplastic rubber gaskets and
adaptor flanges made of stainless steel 304
(1.4301 = V2A) or ABS. Drain grates are
available in stainless steel 304 (1.4301 =
V2A) and anodized aluminum. The covering
support is stainless steel 304 (1.4301 = V2A)
with KERDI laminated on the surface.
The KERDI-LINE channel body is formed
using stainless steel 316 L (1.4404 =V4A)
and features a bonding flange with a KERDI
collar laminated on the surface. KERDI is
a bonded waterproof membrane made of
soft polyethylene, which is covered on both
sides with a special fleece webbing to anchor
the membrane in the thin-set mortar. The
frame and grates are made of stainless steel
316 L (1.4404 =V4A). The channel support
is made of pressure-resistant, expanded
polystyrene (EPS).
KERDI-DRAIN and KERDI-LINE are suitable
for use in residential and commercial
applications, including areas subject to foot
and wheelchair traffic, such as showers
and wet rooms in homes, hotels, schools,
healthcare facilities, etc.
Stainless steel can sustain high mechanical
stresses and is particularly suitable for
applications requiring resistance against
chemicals and acids. However, even stainless
steel is not resistant to all chemical stresses,
and may be affected by hydrochloric acid,
hydrofluoric acid or certain chlorine, chloride,
and brine concentrations, which may be
present in detergents or swimming pools. In
special cases, the suitability of the selected
floor drainage system must be verified based
on the anticipated chemical, mechanical,
and/or other stresses.
Anodized aluminum retains a uniform
appearance during normal use. The surface,
however, is susceptible to scratching and
wear and may be damaged by grout or
setting material. Therefore, these materials
must be removed immediately.
Various configurations of KERDI-DRAIN and
KERDI-LINE are listed by UPC
®, CSA, ICC-ES
PMG and NSF. Relevant industry standard
guidelines for floor drains with integrated
bonding flange include method B422 in
the Tile Council of North America's (TCNA)
Handbook for Ceramic Tile Installation and
Method 326DR in the Terrazzo, Tile and
Marble Association of Canada (TTMAC)
Specification Guide 09300 Tile Installation
Manual.
The KERDI-LINE-FC is roll-formed using
stainless steel 316 L (1.4404 = V4A).
The SHOWERPROFILE-S anchoring
leg is made of recycled, rigid PVC. The
SHOWERPROFILE-S/-R profiles are made
of stainless steel 316 L (1.4404 = V4A) with
KERDI laminated on the backside.
Maintenance
KERDI-DRAIN, KERDI-LINE, and
SHOWERPROFILE-S/-R require no special
maintenance and are resistant to mold and
fungi. The drain grates may be removed to
clean the drain housing and the drain pipes.
