Deadbolts Vs Deadlatches

by **WhiteHat** » 17 Mar 2004 4:10

Hi there,

Newbieish question. I know the difference, I know that with deadlatches you don't have to turn the key 365 degrees (pretty sure).. but why are they called "dead" anything, why not just latches. what makes them more secure than just normal locks?

also a question about lockwood - can't find any information on their site or elsewhere about lockwood locks (of any sort) having modified pins. does anyone know of any with any?

Cheers,
WhiteHat

is the website www.lockweb.com.au? The actual lockwood website doesn't have much info on it, but it links to lockweb.com.au where you can browse through products. I dont now of any sites that tell of 'no. of pins', 'security pins' etc.

Latches are tapered around 45 degrees while deadbolts are cut at 90 degrees. Also, if you have your door open, on a latch you should be able to push the latch part in by just using your finger whereas on a deadbolt, the only way to move it is by using the key (or pick).

I think this is right. :roll:

If not, someone please correct me.

oh, so perhaps a "deadlatch" is one that doesn't have a spring and must be turned by the key or thumb-turn...

www.lockweb.com makes the distinction between deadbolts and deadlatches and normal house locks..

also: Masterlock.com has info on pin numbers.

I've seen a lock with a latch, that when pushed into the lock body about 3/4, releases some sort of spring loaded latch inside the lock mechanism - this makes an audible "click".

When the external latch is pushed out of the lock body by its spring, the internal latch engages the external latch, preventing it from being pushed into the lock body. This also makes an audible "click".

Unlocking the lock with key or thumbturn resets the internal latch.

I guess this could be called a deadlatch, as it works like a deadbolt when locked, and like a latch when unlocked.

A mechanism which is considered to be 'dead', is one which is not susceptible to manipulation by any other force than the means by which it was manipulated to the 'dead' position.

Is that right? Because I can push some deadbolts back into the housing. The door has to be open, so this defeats the purpose of breaking in, however, I assume the lock is worn.

I just thought 'dead' meant without a spring. Which, in turn, does prevent shimming with a credit-card or wire or something.

If you can push a deadbolt back into its housing:

1. It's not fully extended.
2. It's faulty.
3. It's a piece of crap.

Varjeal: Faulty. Its a schlage, and commerical series I believe. I guess I tampered with it too much as a beginner.

a deadlock is a lock that when in the closed position can not be retracted by any other means other than the key or an unlocked handle
a deadlock can be a bolt or a latch the bolt fully extended canot be pushed back into the doors edge a latch will have another smaller piece along side the main latch this component dose not go into the striker plate it is held back once the door is closed causing the latch to deadlock and it to can not be pushed back into the lock body
try it with the door open push the small latch in and then try to push the main latch in after that it shouldnt move
