Are Mortise locks (5 lever) a standard size?

Right. I unscrewed the lock, and photographed/measured it (just count the pixels)

I then opened it up. Since I'm a British craftsman, and not an American, I brushed/blew out the crud, and applied 3-in-1 to most things. An American would have used WD-40...

It still sticks a bit, but moves much more easily.

Further reading leads me to think this is down to a worn "Detainer Curtain Bolt Throw", which I'll look into replacing.

Thanks to all for the pointers.

Regarding Chub/Union/Yale
These manufacturers are all owned by Assa Abloy who also own Mul-T-Lock, Ingersoll, Corbin and MANY others. Assa Abloy only had a licence to the Chubb locks name and this expired (I think) in August 2010. The Chubb door locks etc are now manufactured under the Union name while their secondary security products (window locks etc.) are manufactured under the Yale name.

Most recent dead and sash locks are made to an accepted standard. Sometimes 2 1/2in. is translated as 65mm and 3in. as 78mm so there may be a slight difference there. The screw fitting holes may very and has already been suggested take the lock to a locksmith and compare all measurements with the current stock. The most recent British Standard has a 20mm bolt throw, therefore the existing keep mortice may not be deep enough.

Is this 'premium' lock the current British Standard? I wish I could buy the latest dead lock for £25. I help my son in his locksmith business and his wholesaler charges more than this. Non-British Standard 5 lever dead locks can certainly be found for less than £20 but the current recommended retail price for the the equivalent of the Chubb 3G114E is £50.50 plus VAT.

In the meantime take a look at this wholesaler's web site. You will not have access to prices but there is a lot of information there if you look for the product details. http://www.aldridgesecurity.co.uk


Some pixel counting and googling leads me to...

40 quids worth of lock. I'll look for a spare curtain!

This 3G115 is not a British Standard lock. Your insurance company may have an issue with this.
 
Had a rummage around in the shed and found six mortice locks, BINGO one of the six is the same as yours . If you send me a pm with your address i will pop it in the post to you .

Cheers Bern.

MMUK sorry to hear that you went bump , i came very close to it once back in the 90's just managed to pull through it. I Had to go back to working as an employee for a couple of years .Hope things are good for you now and you are over it .

Wouldn't have it if weren't for a so-called mate (also financial director) fleecing the company for over £600,000 in the space of 3 years :evil:
 
Just happens I have just had to change 5 mortice locks a few weeks ago.
The insurance company wanted B.S.3621 in all 5 exterior doors and none of the new fixings/fitting matched the ones taken out.
I even had to take out material from the actual mortice a couple of times
We used to have a Chubb specialist and lock centre here but as they seem to have fallen out with Union the shelves are full of other stuff now.
I would suggest fixing or locking the door temporary and take you're lock into a Shoe repair/key cutters emporium and get some keys cut if the innards aren't Knackered.
AS mentioned check the tongue and latch are working properly and not fouling the lock catch box, normally caused by door dropping, and worn hinges.
Personally I would get the best lock you can afford and keep you're property for yourself!

The backset (The measurement from the door edge and the key and handle spindle centre) is either 65mm or 75mm depending if you have a door knob or a door handle/lever.
75mm is recommended for a door knob, or you will probably get you're fingers and knuckles caught.
The insurance company wanted B.S.3621 in all 5 exterior doors that i changed and none of the new fixings/fitting matched the ones taken out. All slightly different.

Here's the inside of my lock:

According to various sources, a worn bolt throw is the commonest cause of a sticking lock. Anyone think this looks worn ? :lol: :lol: :lol:

Just to be pedantic the measurements 65 & 78 etc. refer to the size of the lockcase not the distance between the edge of the door and the keyhole. This is the backset as previously mentioned. The backset will increase with the size of the lockcase.

Well spotted!
Please accept my thanks and apologies Foxhunter, 65mm and 78mm are indeed the size of the lock case.
The backset is 45mm and 60mm. respectively. (Stupid boy!)
Please excuse my senior moment. Rodders
 
A new curtain will probably sort that out.

Alternatively, you can fit a 67mm (2.5")3G114e in it's place and you'll be up to the most recent revision of BS3621. The lock will be branded Union, not Chubb, but it's the same model. Assa abloy, who own Union, Yale and countless other lock brands no longer have the legal rights to the Chubb name, so gave had to rebrand all their Chubb products under the Yale and union banners.

My issue is solved - Bern's supremely generous offer has arrived in the post (even the packaging was good!), and the lock is fully compatible with mine,

Since I already had 4 keys cut for mine, I used the bolt throw from Bern's as a donor spare, and my front door lock now works slick and quiet.

So - public and hearty thanks to Bern!

Really pleased that i was able to help out and that the lock was just the right for you.The Dragon has a shop on Ebay and has lots of packaging materials so she kindly donated .

Cheers Bern. :D
 
And finally - I mail-ordered the "bolt thrower" spare, and now have TWO fully working locks!
