Threaded levelling clips are the foundation for precise, lippage-free tile installation. Especially in professional tiling projects with large-format or rectified tiles, every millimetre counts. Karl Dahm offers a comprehensive range of clip types tailored to practical site requirements, making high-quality tiling more efficient and reliable.
Uneven subfloors, varying tile thicknesses, or inconsistent adhesive beds can quickly lead to unsightly lippage. These edge differences not only disrupt the visual result but can also cause complaints. A professional levelling system based on threaded clips solves this problem. The clips are placed under the tiles and secured using a reusable tension cap that is twisted onto the threaded stem, ensuring even height alignment and a smooth tile surface.
Fast and secure levelling without manual correction
Prevents lippage and joint misalignment
Versatile use with various tile sizes and thicknesses
Simple application without special tools
Clean joint lines, even with cross or T-patterns
Available in multiple joint widths (1 mm, 2 mm, 3 mm)
Large pack sizes available for professional use
With options such as base clips, cross clips, T-clips, and long clips for thicker tiles, every installation requirement is covered. Once the adhesive sets, the clips snap off at the designated break point and remain invisible beneath the tiles.
Base Spacers (Standard Length)
Long Spacers (for Tiles up to 30 mm)
Cross Spacers (for Cross Installation)
T-Spacers (for T Installation)
This selection allows flexible adjustment to any tile format and laying style. Whether in a private bathroom or large construction sites – there is the right spacer for every challenge.
Prepare the subfloor: Level, prime and clean thoroughly.
Apply adhesive: Use the buttering-floating method for large formats.
Insert the clip: Slide the clip under the first tile.
Place the next tile: Position it flush with the clip.
Twist the cap: Turn the cap by hand or with a tool until flush.
Allow adhesive to cure: The system holds everything in place.
Remove the clip: Snap off the stem along the joint line. The cap is reusable.
Your joint width and tile format determine the ideal clip type. For sensitive surfaces, use protective pads or washers. All clip types are compatible with Levelmac tension caps and can be mixed and matched freely – offering maximum flexibility on site.
Which clip is right for my project?
Standard base clips are sufficient for most jobs. For edge or joint intersections, cross or T-clips are recommended. For thicker tiles or stoneware, long clips are best.
Are clips reusable?
No – the clips remain under the tile. However, the tension caps are reusable and designed for repeated use.
How many clips do I need per square metre?
That depends on your tile size. As a guide:
60 x 30 cm: approx. 22 clips/m²
60 x 60 cm: approx. 11 clips/m²
120 x 60 cm: approx. 8 clips/m²
Can I combine different clip types?
Yes – all threaded clips are compatible with the same cap system and can be used together.
What is the advantage over a wedge system?
The twist system requires no pliers, distributes pressure evenly and is easier on the back. It is also faster to apply.
Should I buy a set or individual components?
Sets are ideal for beginners or first-time users. They contain everything you need. Pros often choose individual components to top up what they use most.
Is a levelling system always necessary?
Not necessarily – with small formats and perfect subfloors, it may not be required. But for large formats, uneven substrates or time-sensitive jobs, it's a game-changer.
What should I do with delicate tile surfaces?
Use protection plates or disposable pads to prevent marking or pressure points.
How can I install caps without bending down?
Use an installation aid or screwdriver adapter to twist caps while standing – easier on the knees and back.
What if I miss a clip?
With rescue caps or emergency clips, you can fix and level tiles even after installation – great for spot corrections.
Are threaded clips suitable for outdoor areas?
Yes – especially when combined with long clips, they're ideal for thick tiles and natural stone outdoors.
What’s the difference between twist systems and wedge systems?
Twist systems use a screw cap that is turned onto the clip for gradual levelling – no tools needed. Wedge systems push a wedge through the clip and require pliers. Twist systems are quicker and more ergonomic, while wedges can offer stronger tension for heavier tiles.
