MHB MBS-R Lock System, developed around safety and everyday use.
A locking system developed by MHB for steel door projects where fire and smoke safety requirements need to work alongside quiet, user-friendly daily operation. Royal Design Marbella represents MHB across the Costa del Sol and helps project teams review the brief and coordinate the appropriate MHB route.
A safety requirement should not make every interaction with the door feel like an emergency condition.
The MBS-R® system was developed by MHB for doors where fire and smoke safety form part of the project requirements, while daily use still needs to feel quiet and straightforward.
Its defining idea is that the door can operate in normal daily use without an active locking point. The exact system route and configuration need to be reviewed for the individual project.

The locking concept is designed around the way the door is actually used.
MHB presents the MBS-R® as a silent, durable and user-friendly locking mechanism that can function during normal daily use without an active locking point.
Where fire or smoke requirements form part of the brief, the relevant door, system configuration and performance route should be reviewed together rather than treating the lock as an isolated hardware choice.
The applicable door system, locking configuration and performance requirements should be confirmed for the individual project.

The video provides a clearer view of the system logic and the way the locking concept relates to everyday door operation.
The important question is not only how the door performs in a safety scenario, but also how it behaves during normal daily use.
The locking system is one part of the complete steel door configuration.
The door, frame, locking concept and any defined fire or smoke requirements need to be considered together. The objective is a coherent system rather than a collection of unrelated components.


Hardware decisions make most sense when they are reviewed as part of the complete door and project requirement.
Start with the door and the requirement. Then review the appropriate MHB route.
Royal Design Marbella represents MHB across the Costa del Sol, helping architects, designers and project teams review available information and coordinate relevant drawings, quotations and technical conversations. The exact execution route depends on the system, project and MHB process.
Share the door information
Provide the available drawings, opening information and any defined fire, smoke or operational requirements.
Review the MHB route
The available information is reviewed to help identify the relevant system conversation and any further details required.
Coordinate the next information
Drawings, quotations and relevant technical conversations can then be coordinated according to the project and applicable MHB process.
