SFIC deadbolt - need parts

[jeffmoss26]

A while back I got this deadbolt from ebay. The cylinder was damaged, so I ordered what I thought was the proper replacement from Best.
Fast forward to last week when the cylinder arrived:





The cylinder is for the Best 8T3 series deadbolts, apparently my deadbolt is something entirely different and needs a smaller cylinder. The latch is Best so I just assumed the whole thing was made by them.

Can anyone help?

Thanks,
Jeff

reminds me of a Schlage I had.

Looking through the Schlage catalog now, their deadbolts don't seem to have the 1/4" or so lip that mine has.

It's probably completely different. But I still have my Falcon SFIC deadbolts for sale in the "Buy-Sell" section.

If that is the finished length, looks like the tailpiece would be way too short for your application. But if for some reason you think it may work, I can check some measurements for you.

Best comes in 6 pin and 7 pin lengths. A 6 pin will work in a 7 pin lock but not the other way around. Apart from that a SFIC is a SFIC.

I'm not talking about the core, I'm talking about the cylinder that the core goes into. It's a slightly larger version of an SFIC rim cylinder but with different holes on the back, to take the screws from the deadbolt thumbturn.

The core is the cylinder. The core or cylinder goes into a housing. You have a SFIC version that is Best, Falcon, Arrow, Medeco Keymark, Kaba Peaks etc. then you have sever LFIC housings that are unique to manufacturer, you have Schlage, Sargent, Corbin/Russwin, Yale etc. these are not interchangeable within the LFIC or the SFIC housings.

Not sure but you may have a Corbin/Russwin housing.

In one post you say you need a smaller core than a Best which doesn't exist, then you say the housing is a larger version.

I'm confused by your posts.

[jeffmoss26]

I never said I needed a smaller core I need a smaller housing that goes into the deadbolt.
The housing was definitely for an SFIC core. I wish I hadn't thrown the damaged one away. I didn't think Corbin Russwin made any SFIC products, plus the latch is marked Best.
I referred to the part I need as a cylinder because that is what the Best catalog/parts manual calls it: "A23959 outside cylinder"

Here are a few more pictures:

You are a wee bit confused as some terminology is cross used with other locks. He did not say he needed a smaller core, he said cylinder.

While a rim or mortise cylinder normally refers to the entire lock(plug, pins etc), a SFIC mortise/deadbolt cylinder is a separate unit because the core is not in the cylinder (sometimes referred to as housing). In IC locks the core is NOT a cylinder. I believe this is what is causing you confusion.

If you look in the original post you can see how the cylinder/housing is sticking out the front of the outer collar. If you look in the other pictures a few posts up you can see the lip on the inner collar. This is preventing his cylinder/housing from going into the outer collar so he needs a different or smaller cylinder/housing.

Did that explain things a bit better?

[jeffmoss26]

Thanks for trying to clear it up.

[cledry]

OK, he needs a smaller housing. That is simple, just turn it down to fit in the collar.

I see what you are saying, yes BEST uses confusing terminology. Only BEST refers to the housing as a cylinder AFAIK. All other manufacturers refer to the core as the cylinder and the housing is the part that accepts this. I use the terminology that is pretty much industry standard.

Actually with Best the housing would be the deadbolt body. The (mortise) cylinder (body/housing) fits into that "housing/collar" and the core fits into the cylinder.

All other manufacturers refer to the core as the cylinder and the housing is the part that accepts this.

I think it would be more accurate to say that a SFIC core is more accurately represented by the lock plug/keyway. Other manufacturers "cylinders" houses the plug, pins etc. usually in the form of a mortise or rim cylinder. Now for a deadbolt, this cylinder is inserted into the housing/collar and attached with screws etc. It is the same with SFIC. The cylinder goes into the deadbolt housing and is screwed into place but since it does not have the pins in there it needs to accept a SFIC core.

Now, unless I misread your post due to a lack of sleep, that should be right.

[cledry]

All other manufacturers of SFIC and LFIC also refer to the core as a cylinder AFAIK. The core or cylinder goes into the housing if it is a rim or mortise. It goes into the lock body if it is a deadbolt or knob/lever.

When I place an order for a SFIC rim housing or a mortise housing from my suppliers they know what I am talking about. We never order BEST, it is usually another SFIC supplier. BEST still tends to concentrate on the end user and institutional end of the market.
