Jamb mounted door closers provide an effective, concealed alternative to traditional overhead closers. By integrating the mechanism into the door frame, these closers maintain aesthetic appeal while delivering robust and reliable performance.
Samuel Heath has been manufacturing high-quality concealed door closer technology for over 60 years. As the demand for durable and vandal-resistant solutions increases, particularly in social housing, care homes, and mental health institutions, Powermatic R100 and Powermatic R108 stand out as trusted solutions for architects and main contractors.
Jamb mounted door closers – an overview
A jamb mounted door closer is discreetly installed within the door frame rather than being surface-mounted. This design enhances the aesthetic appeal of a space while improving safety and longevity.
Key benefits of jamb mounted door closers include:
- Enhanced security – Hidden within the door frame, reducing the risk of tampering or vandalism.
- Space efficiency – Ideal for tight corridors and small spaces where an overhead closer might obstruct movement.
- Unobtrusive design – Preserves the visual appeal of an interior while maintaining full functionality.
- Reliable fire door performance – Ensures fire-rated doors close securely in the event of a fire.
Difference between jamb mounted and overhead closers
Overhead door closers have long been the standard choice for controlled door closing. However, in high-risk environments like social housing and healthcare settings, their surface-mounted design presents several disadvantages:
| Feature | Overhead Door Closers | Jamb Mounted Door Closers |
|---|---|---|
| Visibility | Highly visible, prone to vandalism | Fully concealed within the door frame |
| Vandalism Risk | Easily tampered with or removed | Hidden and inaccessible to damage |
| Aesthetic Appeal | Bulky, affects design aesthetics | Clean architectural finish |
| Ligature Risk | Potential hazard in mental health settings | Reduces self-harm risk |
In environments where safety, durability, and cost-efficiency are paramount, jamb mounted concealed closers are the superior option.
Advantages of concealed closers in door frames
Architects and contractors working on social housing or healthcare projects often face challenges related to vandalism, maintenance costs, and compliance with safety regulations. Jamb mounted door closers offer distinct advantages:
Prevents vandalism and tampering
In social housing settings, overhead closers are frequently targeted for vandalism, leading to costly repairs and safety risks. Concealed door closers like Powermatic R100 and Powermatic R108 eliminate this issue by being hidden from view.
Improves fire door reliability
A damaged or missing overhead door closer compromises the integrity of a fire-rated door, failing to contain fire and smoke as required by regulations. Concealed closers ensure compliance by reducing the likelihood of damage and maintaining reliable operation.
Reduces long-term maintenance costs
While overhead closers are cheaper upfront, repeated repairs and replacements due to vandalism or misuse make them a false economy. Investing in a high-performance concealed door closer significantly reduces lifecycle costs.
Enhances safety in mental health and care environments
Overhead closers present a ligature risk in mental health facilities and care homes. Jamb mounted closers eliminate this hazard, making them a preferred choice in safety-critical environments.
