Swedoor Intermediate Hinge For BD Door
Description
It can be a challenge to update doors in older properties where the frames follow the older building standard. Swedoor intermediate hinge for BD door (fire door) offers a technical and practical solution that makes it easy to combine classic door frames with modern door leaves. Older doors were often manufactured with traditional pin hinges, which differs significantly from today's modern snap-in standard. With this smart hinge adapter, new interior doors and fire-rated doors can be installed directly in the existing frame without a complete and time-consuming frame replacement being required. The product is delivered in a complete set for stable installation.
Sustainable door renovation and preserved property character
Keeping the existing door frame saves time, money and materials during renovation. It also minimizes damage to adjacent wallpaper, lining and wall coverings. By using reliable hinge accessories, it is possible to upgrade the door function to modern standards, while preserving the original joinery and architectural charm of the house intact.
Technical function and load-bearing capacity for fire doors
This intermediate hinge acts as a mechanical transition between the old hinge pins in the frame and the modern snap-in mount on the new door. Since a BD door (fire door) is often heavier than a regular interior door, this hinge is designed to provide an extra stable and precise door suspension that prevents sagging door leaves. The set contains robust metal parts as well as the associated plastic bushings and spacers, which guarantees a quiet and compliant closing function for a long time to come.
- Compatibility: Fits older door frames with mortise hinges (old standard manufactured before 1972) as well as new doors equipped with snap-in fasteners.
- Application: Interior doors, BD doors (fire-rated doors) and heavy residential doors in older properties.
- Material: Durable, galvanized steel for high corrosion resistance, dimensional stability and optimal load-bearing capacity.
- Installation: Easy installation on the existing frame without the need for advanced tools or milling in the wood.
