Usage
The Dorma BTS 75 V floor spring pivot is designed for use with single and double-action doors, providing concealed closing control in commercial and public buildings where seamless aesthetics are required.
Advantages
- Completely concealed installation preserves door appearance and architectural design.
- Suited for both single- and double-action doors to maximize application flexibility.
- Adjustable closing force accommodates various door weights and sizes.
- No external moving parts reduce maintenance needs and risk of damage from tampering or vandalism[6].
- Lack of hold-open function may be a limitation for certain applications requiring the door to remain open at a set angle.
Specifications
- Designed with robust internal mechanisms; suitable for doors up to approximately 1100 mm wide depending on configuration[3][7].
- BTS series is known for durability, suitable for high-traffic environments; meets relevant international standards (e.g., EN1154, fire resistance dependent on model)[3][7].
- Adjustable closing force typically EN size ranges; features allow smooth operation even with heavy-duty usage[5].
- Dorma’s floor-concealed mounting ensures clean lines, leaving no visible hardware on the door surface. The unit is provided without a spindle (axe) or cover plate (plaque de finition), allowing customization during installation.[5][6]
How it works
The BTS 75 V sits recessed in the floor beneath the pivot point of the door. When the door is opened, an internal spring mechanism controls its return to closed position at an adjustable speed. All operating components remain hidden from view within the floor structure.[6]
