The KERDI-DRAIN adaptor kit is designed
to convert clamping ring drains by equipping
them with an integrated bonding flange. The
adaptor kit includes a stainless steel adaptor
ring with an over-molded rubber gasket
and a variety of perforated hole patterns
that align with most common clamping
ring shower drains. The adaptor ring
replaces the clamping ring and is attached
to the drain body using the clamping ring
bolts. This connection is made watertight
via the rubber gasket and KERDI-FIX
adhesive/sealant. The integrated bonding
flange slides into the adaptor ring, with
the over-molded rubber gasket ensuring a
watertight seal. Commercial KERDI-DRAIN
adaptor kits feature a 7-1/2" (191 mm)
diameter adaptor ring and are available
with a stainless steel bonding flange or an
ABS bonding flange. The ABS bonding
flange is available in two sizes (standard or
extended length) to accommodate different
tile assembly thicknesses. The residential
KERDI-DRAIN adaptor kit features a 5-1/4"
(133 mm) diameter adaptor ring and an ABS
bonding flange. The KERDI-DRAIN adaptor
kit is particularly useful in renovations where
the clamping ring drains are difficult to
replace with the standard KERDI-DRAIN
(e.g., when they are set in concrete slabs).
The grate assembly consists of a height
adjustment collar, lateral adjustment ring,
and drain grate or covering support. The
grates are installed in conjunction with
a height adjustment collar and lateral
adjustment ring, which are made of ABS
or stainless steel, to allow for simple and
convenient adjustment when setting the
tile. Drain grates are available in stainless
steel with a chrome, polished or oil-rubbed
bronze finish and in anodized aluminum
with a brushed copper, brushed brass, or
brushed nickel finish. The polished stainless
steel grates are available in 4" (100 mm)
-square, 6" (150 mm) -square and -round
versions. All other grates are available in the
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 grate,
available in stainless steel with a brushed or
chrome finish.
Option B is a stainless steel grate with
square perforations, with brushed or
chrome finish.
Note: Remove the protective foil from
the chrome drain grate after installation.
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).
