If hardware, including locks and latches, on a fire door are unprotected, this inevitably reduces the door's fire protection performance.

Lorient currently provides a universal lock 'jacket' which enables family groups of mortise locks to be incorporated in fire-resisting door leaves. But now, Lorient is launching a larger, European DIN standard lock jacket that provides 30 minutes fire protection.

The 'jacket' comprises a one-part envelope suitable for FD30 configurations which simply wraps around the kit for a neat and easy installation.

Tests have proven suitability for locks with a common height of 165mm and verified a fire performance meeting the requirements of BS 476 Part 22:1987. Tests conclusively reveal that families of upright mortise lock cases incorporating latch, lock, deadlock, night latch and sliding door lock can all be protected.

Both lever and cylinder operators were included and there is no requirement for additional intumescent material to be placed behind the strike plate, or for the door and/or frame seal to be continued past the forend or strike plate.
