Invisible Passive Fire Protection

The TECTUS TE 340 3D FR remains fully concealed when the door is closed, maintaining a clean, uninterrupted look while providing vital passive fire protection. Designed with integrated intumescent material, it supports 30-minute fire resistance without the need for additional kits.

Ideal for interiors where visual consistency is important, these hinges remove the distraction of visible door hinges. Select from six high-quality finishes, including stainless steel, matt black RAL 9005, and bronze, to complement door handles, locks, and other ironmongery. Cover plates are included to hide the fixing screws for a discreet, professional finish.

3D Adjustability for Precise Alignment

These TECTUS fire rated hinges feature full three-dimensional adjustability, allowing simple and accurate alignment after installation. Adjust height, side, and compression independently:

• Compression adjustment: ±1mm
• Lateral adjustment: ±3mm
• Height adjustment: ±3mm

This level of fine-tuning ensures that doors operate smoothly while maintaining their fire integrity, even after seasonal environmental door movement. Easy adjustment is especially important for fire doors, where a consistent gap between the door and frame must be maintained to comply with regulations.

Robust Construction for Demanding Environments

Manufactured to the highest standards, the TE 340 3D FR hinges are designed for durability in heavy-duty settings. They support door weights up to 80kg per pair and are non-handed, simplifying specification and installation. 

This load bearing is based on two hinges with a 1450mm door gap. For heavier fire doors, consider the TE 540 3D FR to suit 120kg adjusted door weight. Alternatively, the TE 640 3D FR TECTUS hinges suit doors up to 200kg.

The maintenance-free slide bearings eliminate the need for lubrication, ensuring dependable operation throughout the life of the door. Regular checks for smooth operation are recommended as part of a fire door maintenance programme. Do not apply oil to these hinges, as it may impair their performance.

Versatile Applications Across Fire Door Projects

Compatible with timber, steel, and aluminium frames, these concealed door hinges are a flexible solution across a wide range of projects. Whether fitting high-specification residential doors, hotel room doors, or fire doors in public buildings, the TE 340 3D FR ensures fire door safety compliance without compromising visual or functional standards.

A cutter diameter of 24mm is required, with a 30mm collar ring. Specific templates, universal milling frames, and drilling jigs are available to achieve consistent results. Contact our team for support with these additional installation tools and accessories.
