MSL locks for solid leaf doors

Further development of the MSL Tribloc and CASA lock range

With the new MSL product AutoTriBloc, ASSA ABLOY has developed its Tribloc 1850 further, making comprehensive improvements to function, security and ease of installation. The lock version is now also available in the single-point locking system version.

The new CASA Alpha SV also adapts to its surroundings like a chameleon and can be installed in any wooden door. All the advantages of the AutoTriBloc can also be found in the new CASA Alpha SV mortise lock.

Advantages of both locks at a glance:

  • Mechanical high-end lock for solid-leaf doors
  • Offers high burglary and fire protection
  • Panic and DIN direction can be switched
  • New spring concept with strong compression springs for heavy handles
  • Offset control latch, DIN universal
  • NEW: Available as a single-point and multi-point locking system

Secure locking technology, optimum intrusion protection

Thanks to the integrated panic functions E and B, both locks (AutoTriBloc and CASA Alpha SV) are ideally suited for escape doors. A mechanical automatic locking system with an enhanced bolt locks the door securely after it is opened each time, thus offering high intrusion and fire protection. As a mechanical locking system for solid leaf doors, both locks can be used in a wide variety of ways in public and private buildings, both in new buldings and renovations.They can be used on main entrance doors to apartment buildings, on accesses to parking garages or on large offices and archive rooms, for example. Solid leaf doors in laboratories, medical practices or cultural buildings such as concert halls and libraries can also be fitted with the locks. Fitters, architects and developers will all benefit from this further development and high functionality.

Variety of versions to suit installation type and design

One noteworthy feature is the new MSL lock's capacity to adapt to different door situations. Thanks to the reversible DIN door opening direction and a reversible panic side, the single-point and multi-point locking systems can be changed quickly and easily. It is also simple to retrofit. If a door is renovated or if there are new requirements for the locking solution, an existing Tribloc 1850 or CASA 1718 or 1719 can be replaced with the new lock with minimal effort on the door. The large load capacity is particularly advantageous – the lock now also allows the use of heavy door handles. This is thanks to a new spring concept, which uses a pressure spring instead of a volute spring. As a result, heavy, modern handles can be fitted which highlight the sturdy character of a solid leaf door, thus allowing architects significantly more scope for design.
