Fire Rated Mortice Locks & Latches

Fire Rated Mortice Locks & Latches

When you're looking at locks for fire doors, it is important that you remember the lock its self needs to be fire-rated for whatever grade fire door you have.

Most of our fire-rated locks are suitable for 60 minute fire doors (FD60) however some may only be suitable for 30 minute fire doors (FD30) - this is very important, as a 30 minute fire rated lock on a 60 minute fire door compromises the resistance against fire.  However an FD30 door with a 60 minute fire rated lock would of course be fine!
