About Bjarnes System
Bjarnes System is part of U-nite Fasteners Technology AB and focuses on clips, tools and technical advice for standing seam metal roofing. The brand is built around a clear goal: to simplify installation work with fastening solutions developed for real roofing conditions.
With a specialised range of clips and tools, together with project support and product guidance, Bjarnes System helps professionals work with safer, more efficient and more controlled installations from planning to completed roof.
Krabban for insulated roofs
Krabban is Bjarnes System’s fastening solution for installation on insulated roofs, developed for standing seam roofing where insulation, fastening and movement all need to work together over time.
The telescopic sleeve helps provide the required compression of the insulation without risking damage to the sheet metal. Because the system is installed independently of the insulation joints in relation to the seam, it also helps reduce the risk of gaps in the insulation build-up.
Clipdriver DF
Clipdriver DF is an installation tool created for faster and more efficient clip fastening in sheet metal roofing. It is designed to improve repeatability on site and make clip installation easier to control.
With automatic feeding for both clip and fastener, depth control and 15 collated clips per strip, Clipdriver DF is built to support speed, ergonomics and consistent installation quality during demanding roofing work.
More Bjarnes System products
Beyond Krabban and Clipdriver DF, Bjarnes System offers a broader range of clips, banded sliding clips, installation tools, gutter brackets and Chaner for standing seam metal roofing.
The range covers both installation directly to substrate and solutions for insulated roofs, making it easier to match the right product family to the roof build-up, seam type and project conditions.

If you are planning a standing seam roofing project, Bjarnes System can help you move from product questions to a more complete fastening decision. We support contractors and project teams with technical advice, clip selection and guidance based on real project conditions.

What is Krabban?
Krabban is our fastening system for insulated roofs within standing seam metal roofing applications.
The system uses telescopic sleeves to help manage compression in the insulation, reduce the risk of damage to the sheet metal and lower the thermal bridge effect compared with traditional penetrating metal clips.
When is Krabban a better choice than standard clip fastening direct to substrate?
Krabban is designed for insulated roof constructions, where the fastening needs to work through the roof build-up without compromising the sheet metal or insulation performance in the same way as a direct-to-substrate solution.
If the project involves exterior insulation, Krabban is often the more relevant system to evaluate first.

The manual includes important selection support, including combination tables for insulated roofs, and can be used as a practical reference during clip selection and project planning.
