Schlüter-KERDI-LINE-TF  Tile grate with stainless steel frame

Schlüter-KERDI-LINE is a multi-piece, linear drainage system for creating floor-level showers with ceramic tiles, natural stone or coatings. It consists of a formed stainless steel channel body as well as different grate/frame assembly options. These can be continuously adjusted to different floor covering thicknesses using the supplied installation aid. KERDI-LINE is suitable for intermediate installation in floors or wall areas.

The frame assemblies are available in 3 versions:

• A profile frame with a 10 mm wide visible surface in a brushed, polished or powder coated finish
• A contour frame with elegant design grates
• A TF frame with minimal visible surface and optimal edge protection.

Schlüter-KERDI-LINE-H with horizontal drain features an integrated odour trap and a drain body.

Height of channel support: DN 40 (40 mm) = 78 mm DN 50 (50 mm) = 97 mm

Schlüter-KERDI-LINE-H 50 G2 with a horizontal forward facing drain features an integrated odour trap. In compliance with DIN EN 1253, it has a drain capacity of ≥ 0.8 l/s with an accumulation height of 2 cm and a water trap height of 50 mm.

Channel support height: DN 50 (50 mm) = 120 mm

Schlüter-KERDI-LINE-F with a horizontal forward facing drain features an odour trap integrated in the drain body.

Height of channel support: DN 40 (40 mm) = 60 mm DN 50 (50 mm) = 97 mm

Schlüter-KERDI-LINE-V, -VS and -KERDI-LINE-VOS for vertical drainage – for example, through the floor level – is available with various equipment. KERDI-LINE-V has an odour trap built into the drain body. KERDI-LINE-VS and KERDI-LINE-VOS are delivered with a trap section – including with off-centre drain for KERDI-LINE-VOS.

Channel support height: DN 50 (50 mm) = 24 mm

Schlüter-KERDI-LINE-V 50 G2 for vertical drainage features an integrated odour trap. In compliance with DIN EN 1253, it has a drain capacity of ≥ 1.0 l/s with an accumulation height of 2 cm and a water trap height of 50 mm.

Channel support height: DN 50 (50 mm) = 48 mm

All drainage systems listed are available for contour frames with design grates as well as for profile frames and TF frames!

In case of KERDI-LINE-H 50 and KERDI-LINE-H 40, the channel body is inserted into the appropriate polystyrene channel support for quick and easy installation. The channel body and channel support of KERDI-LINE-V, KERDI-LINE-H 50 G2 and KERDI-LINE-F are permanently connected.

The perimeter of the channel body consists of an adhesive flange that is coated with a collar from the KERDI waterproofing system. It ensures the reliable connection of the channel body to the bonded waterproofing assembly in the floor area and on upright walls. In conjunction with the waterproofing systems Schlüter-KERDI, Schlüter-DITRA, Schlüter-DITRA-HEAT or Schlüter-KERDI-BOARD and the matching system adhesives Schlüter-KERDI-COLL-L or Schlüter-KERDI-FIX, installers can create certified bonded waterproofing assemblies with connecting linear drainage.

KERDI-LINE is a system component that complies with the German waterproofing standard DIN 18534. Together with the above-listed Schlüter-Systems it has general technical approval (abP) in Germany. Please refer to the respective product data sheets for information about the moisture exposure classes according to abP. KERDI-LINE is a system component with European Technical Assessment (ETA) according to ETAG 022 (watertight covering kits). The above-mentioned Schlüter products tested with KERDI-LINE carry the CE mark.

Note: Schlüter-KERDI-LINE and frame assemblies must be installed with cement-based tile adhesives. The use of acetic-crosslinking silicone is not permissible on channels, frames and grates.

The visible surfaces of the profile frame and grates – whether solid or embossed – are made of brushed, polished stainless steel or powder coated stainless steel. A tile grate is available for the profile frame and for the TF frame. In addition, we offer a frameless covering support that is suitable for any height (KERDI-LINE-D).

Note: Before using the TF frame, you must check whether the distance between the channel body and the wall is correct.

Installation at wall perimeter

1. Tightly adhere the KERDI collar and the Schlüter-KERDI-KERECK internal corners included in the scope of material with KERDI-COLL-L.
2. Then apply the thin-bed mortar in the area of the drainage channel.
3. Depending on the version, the TF frames have a fixed height and are embedded into the mortar bed using their tile leg.
4. Apply thin-bed mortar to match the covering material and align the covering to the correct height, somewhat higher than the frame.
5. Remove the spacer strips after curing.
6. Then insert the fully tiled grate.

Note: The use of acetic-crosslinking silicone is not permissible on channels, frames and grates.

The channel bodies with a length of up to 120 cm are made of formed stainless steel V4A (material no. 1.4404 = AISI 316L). From a length of 130 cm, the channel bodies are made of angled, welded and pickled stainless steel V4A (material no. 1.4404 = AISI 316L). They feature a flange with a pre-adhered KERDI collar. This material is a waterproofing membrane of soft polyethylene with a special fleece fabric laminated on both sides. It has a special fleece fabric laminated on both sides.

Depending on the type, the drain bodies are made of high-impact resistant polypropylene (PP) or acrylonitrile butadiene styrene (ABS). The odour trap is made of fibre-reinforced polypropylene (PP). The stainless steel frames and grates are available in the following material version: V4A material no. 1.4404 = AISI 316L. Finish options of profile frames and grates:

• EB = brushed stainless steel
• EP = polished stainless steel
• EC = stainless steel, powder coated

The channel support is made of high impact resistant, expanded polystyrene (EPS).

Material properties and areas of application

The channel bodies, frames and grates are tested, certified and classified as K3 according to DIN EN 1253. This class refers to areas without vehicle traffic, such as wetrooms in apartments, nursing homes, hotels, schools, and public washroom and shower facilities, for example.

Channel bodies, frames and grates are suitable for wheelchair traffic.

KERDI-LINE in the brushed stainless steel V4A version (material no. 1.4404 = AISI 316L) is especially suitable for applications requiring resistance against chemical exposure and high mechanical stresses. However, stainless steel of quality 1.4404 is not resistant to all chemical stresses. This stainless steel is not suitable for stresses such as hydrochloric and hydrofluoric acid or certain chloride and brine concentrations, for example. In certain cases, this also applies to seawater pools. The suitability of a proposed floor drain system must be verified based on the anticipated chemical, mechanical and/or other stresses. Aggressive cleaning products must not be used.

KERDI-LINE-TF makes it more suitable for commercial projects, such as hotels, for example, where the tile pan is regularly removed.

The profile frames as well as the matching stainless steel grate styles A, B and C are also available with textured finishes. These are surfaces with a natural appearance. The stainless steel is pre-treated, then powder coated with a polyurethane covering. The coating is colour-stable, as well as UV and weather-resistant. The visible edges must be protected against abrasion or scratching.
