| Night latch |
Commonly known as Yale or night latch, rim locks are held in place by long screws inside that extend through the cylinder.
They are attached to the inside surface of a door and operate the locks attached to it. This type of lock automatically locks the door when shut, deadlocking it.
Like other locks, rim cylinders come in a variety of styles, but in only two sizes.
Rim Night Latches | Mon deadlocking
The main bolt has a lead rounded edge and is spring loaded. As
you turn the knob the latch withdraws to let you open the door. To simply close
the door you just have to push the door back into the frame. The kind of locks
always needs to be unlocked from outside.
Rim Night
Latches | Key Deadlocking
Similar to the lock above, you can unlock the door from
outside. The difference is that you can deadlock the latch from outside with
the simple turn of a key. This prevents the penetration of the door with a card
or piece of plastic from outside.
Rim Night
Latches | Automatic Deadlocking
This lock has a deadlocking pin just above or either below the
latch. When the door is closed, the pin weighs down into the latch deadlocking
it.
Rim Night
Latches | BS 3621 thief
resistant
Locks like this are marked by the British Standard Kite mark.
This higher quality rim night latch has a flat bolt which juts out into the
frame as the door closes, ensuring the door stays closed.
Roller
Bolt Rim Night Latch
Roller bolts have a loaded spring that is designed to hold the
door in its frame without locking. No key is required. To release the door you
have to either push or pull the door. These kinds of doors may not be suitable
in the cases of a fire. Speak to a locksmith before installing one.
