Usage
The Dorma BTS 84 floor pivot with 90° hold open function is designed for concealed installation in swing doors, offering controlled and reliable closing in commercial or residential environments where aesthetics and seamless movement are key.
Advantages
- Completely concealed within the floor for an unobtrusive appearance and improved building aesthetics[6][8].
- Suitable for both left- and right-handed single- or double-action doors, increasing versatility[3].
- Adjustable closing speed to match user preference or specific project requirements[5][7].
- Durable mechanical design ensures consistent performance with minimal maintenance needs[3][6].
- The absence of a visible spindle (supplied without axis) requires suitable selection during installation, which may limit immediate compatibility.
Specifications
- Design: Concealed floor-mounted door closer system; body manufactured from robust materials ensuring long-term reliability.
- Durability: Engineered for frequent use in high-traffic areas; compliant with relevant EN standards such as EN1154 (depending on configuration)[3][7].
- Performance: Supports doors up to approximately 1100 mm wide; provides a mechanical hold at a fixed angle of 90° when required[5][7]. Closing force typically adjustable to suit various door weights.
- Differentiating Feature: Unobtrusive integration into the floor maintains architectural integrity while enabling precise control of door movement. Delivered without spindle/axis and finishing plate—accessories must be ordered separately according to the specific door setup.
How it works
The Dorma BTS 84 is installed beneath the threshold, connecting to the bottom edge of a swing door. The internal mechanism governs opening and controlled self-closing, while an integrated function holds the door open at exactly 90°, enhancing access convenience when needed.
