Lever -v- Detainer - Chubb & Boda

[outlawuk]

Hello all, my first post. A friend asked me to choose and buy a lever lock for him so on the basis that there's nothing better than spending other peoples money I bought him a Chubb 3G135!
I've been reading loads on here and elsewhere about lever-type locks and it is all highly fascinating but I cannot find anywhere an answer to this question:
What is the difference between a (Chubb) Lever -v- Detainer?
The detainer from a youtube video looks a more 'elegant' design but that's hardly the priority in designing a lock? That led me to discover Boda. If I were fitting a new lever lock to a door now should I buy another Chubb 3G135 or an 8x lever Boda (BodaGuard, 492 or 2928 that looks like a rim-lock).
I presume that the Chubb 3G135 is not a detector?
Presumably the fact that the 3G135 has restricted keys makes absolutely no diffference from the point of view of someone picking the lock?
If one were looking for a really effective lever lock today is Boda in fact the obvious solution or is the security more than just about the 8 levers and (eyebrow-raising, lovely-looking BodaGuard!) double-bitted key?
Thanks

The chubb detainers use a different design to the traditional bolt stump passing through gate design of the majority of lever locks.

Its a similar principle in that a moving element is blocked until all levers are aligned, however the actual 'gate' of the levers sits right in the edge of the lock.

If you imagine this fitted correctly in a door with heavy duty frame that opens inwards, then the 'drilling point' of this lock will fall behind the frame of the door making a destructive entry a right pain in the backside.

These locks also lack feel. Due to the tension applied being shared across many parts its hard to get a feel between false and real gates in the levers.

Iv seen them picked in a vice but not a used one in the door under pressure.

They are very well made locks and a lock change is a quick change of lever pack with new keys.

Where are you located? If you're in the UK you need to check that the lock you fit is not just of excellent quality, but also complys with your insurance companies specification.

I don't know about the Boda, but the 3G135 or 3G110 are not BS rated, and as such may not satisfy your insurors.

The 110 or 135 were (usually) acceptable equivalents as far as most insurance companies are concerned.

Chubb have not produced detector locks for around 40 years.

On the basis of security in obscurity a 135 or Boda is an excellent choice. Very few locksmiths can deal with either lock.
