Bjarnes System Chaner
Chaner for roof hatches and sheet metal roofing
What Chaner is used for
Our Chaner is a narrow, specialist product in the Bjarnes System range. It is used where a roof hatch hinge solution is needed in sheet metal roofing work, rather than a standard clip for fixing the roof covering itself.
Because this is a highly focused product, the key decision is usually straightforward: if the project involves a hatch detail, you need the correct dedicated component, the right quantity per hatch, and support that fits the surrounding roof build-up. That is where we can help.
Chaner details in our handbook
Below you can open the handbook reference for Chaner. This is the key source for the product entry and the clearest place to confirm the basic product information tied to this page.
Because Chaner is a tight, specialist entry rather than a broad system range, the handbook section is short and direct. If your project also includes surrounding hatch details or adjacent sheet metal work, we can help you choose the right overall solution.
Need help with the right Chaner solution?
If you are detailing a roof hatch and want to make sure the hinge solution fits the surrounding sheet metal work, talk to us early. We help contractors, roofers and project teams choose the right Bjarnes System components for the job.
We can also help when Chaner is only one part of a wider roofing detail and you want a more complete recommendation instead of ordering parts in isolation.
What is Chaner used for?
Chaner is used as a hinge solution for roof hatches. It is not a general standing seam clip for fixing the roof covering, but a dedicated part used when the project includes a hatch detail that needs the correct opening and fastening hardware.
When should I choose Chaner instead of standard Bjarnes clips?
You should choose Chaner when the task is related to a roof hatch rather than the normal fixing of sheet metal roofing to the substrate. Standard clips handle the roof covering itself, while Chaner belongs to the hatch-related detail.
How is Chaner installed and supplied?
The handbook states that Chaner is mounted in pairs and used as 4 units per hatch. That makes it important to think in terms of the whole hatch detail rather than ordering it like a loose general-purpose fastening.
Can Unite help us choose the right Chaner setup for a project?
Yes. If you are unsure whether Chaner is the right choice, or how it should sit alongside the surrounding sheet metal roofing detail, we can help you assess the application. That is often the fastest way to avoid ordering the wrong component or missing related parts in the hatch area.
