Corbin Russwin Pyramid 'High Security' Cylinders

[locksmistress]

Has anyone run into one of these in person - I checked the site search and didn't come up with anything? They're at Corbin-Russwin.com (sorry, can't get beck for the exact address - error - it's easy to find though) under Catalogs and Technical Information.

I'm curious about how the 'pick resistant' pins hold up - they are in the owners manual under the Technical Information header. Master and bottom pins have false-shear details - The grooves look too shallow to do as much harm as a regular spool pin... I've never tried anything with that particular shape so I suppose I'm grossly undersetimating it's potential wickedness.

There's also the peculiar combination of stainless steel pins and nickel silver blanks as well as the logo which, on the front of the cylinder, looks exactly like Shlage's Everest.

Sorry for the lack of web-savvy on the address.

It looks like they have serrated pins which from what I understand can be more difficult than spools.

never seen them in person, but I have a book with quite a few very good
diagrams.

the pins interlock and need to be rotated to dis-engangle:

Code: Select all

 
 I
[ ]

the top pins look like an "I", and the key pins (or rather the pins on the
bottom, because master pins are also similar) surround the top pins like a
dovetail joint on a piece of furnature and they can only un-slot when they
are turned inline with the rotation of the plug AND lifted to the shearline.
allowing the top pin to remain and the bottom pin to rotate away.

the keys would be similar to the medeco keys and could be on different
angles also so that the pins may have to rotate different amounts master
pins are therefore have a minimum size so that they can interlock with
both the bottom pin and the top pin.

kind of hard to explain - diagrams are easier.

nasty looking bastard.

which has an awesome diagram of what I'm talking about.

enjoy!

Thanks, WhiteHat - but I'm not talking about Emhart. Pyramid is the new high security from Corbin - they've all but discontinued the Emhart last I heard.

Pyramid for sure does not have interlocking pins. The keyway is beefier than normal, patented and completely incompatible with any existing Corbin systems. It's pinned on a pre-System 70 10 depth, 2 step system and available only in 7-pin with no angle cuts on the key.

I wish I were better at this web-link thing. Practise is the only thing for it -I think this will take you straight to the front page of the Pyramid Owners manual - with a trasluscent guts shot on the front and specs on the pins on page 4:

It's really not half as interesting as Emhart - that's partly why I'm interested - are those serrated pins then?

Thanks

Those pins are often referred to as double spools. They are meant to fool you into thinking that you got past the spool, when in fact you have grabbed the next cut.

Serrated pins often have more grooves and of a narrower type.
