Usage
The Dorma BTS 84 pivot without hold-open, spindle, or cover plate is designed for use as a concealed floor spring in interior and exterior doors where discreet door closing and controlled operation are required.
Advantages
- Total concealment preserves the visual aesthetics of the entranceway and architecture.
- Enables pivoting door movement with reliable automatic closing without exposed moving parts.
- Compatible with a wide range of door materials including metal, wood, and aluminum.
- No fixed open position increases security by fully closing after every opening cycle.
- Lack of finishing plate or spindle means additional accessories must be specified separately during installation (minor drawback).
Specifications
- Compact concealed design; body installed within floor cavity under the threshold for minimal visibility.
- Engineered using robust mechanical components for long service life under regular usage conditions.
- Carries industry-standard certifications such as EN1154 when complete assembly is used; maximum supported door width typically up to approximately 950–1100 mm, depending on application.
- Suits single- or double-action doors; available closing force sizes adapt to varied leaf weights.
How it works
The BTS 84 mechanism is floor-mounted beneath the doorway. The pivot connects the bottom of the door to this closer. Once opened, internal springs return the door smoothly to its closed position by guiding movement through its concealed hydraulic mechanism. Hold-open function is excluded in this variant for secure closure after every use.
