Deadbolt sleeve

[soksavik]

I went to a local locksmith for advice on deadbolts for my house, and purchased four US Lock deadbolts that he recommended (US1660DL26D) with Schlage Primus mortise cylinders from him. I've since learned that mortise cylinders come in different sizes, and these deadbolts cannot accommodate the 1 1/4" Schlage Primus mortise cylinders; they're made for a 1" mortise cylinder. I've installed the sleeve and circular spring that were included with the lock; even so, I can pry the sleeve away from the door by hand. I'm talking both to my locksmith and to US Lock about possible solutions, like ordering a thicker cylinder sleeve. But I thought I'd ask if anyone here has come across this problem and has a solution. Including recommendations for another brand deadbolt that can fit these Primus mortise cylinders if the US Lock ones cannot be easily adapted.

Do you mean rim cylinder instead of mortise cylinder? Does the cylinder have a tailpiece on the end? If so it may be to long and is not allowing the two halves of the deadbolt to secure together properly. Some tail pieces need to be cut down to accommodate different door thicknesses.

It's a LORI style deadbolt that mortise cylinder screw into.. we talked in chat, his door isnt thick enough for the "cones" to make good contact and there's a gap. I think the cylinders are 6 pin and just a dash too long.

Squelchtone is correct. It is a mortise cylinder (two actually; dual deadbolt) and they are about 1/4 inch too long to screw in sufficiently far. The manufacturer apparently sells these with a 1" mortise cylinder, whereas my Primus cylinders are 1 1/4".

A thicker cylinder sleeve would solve the problem. As would a thicker door. Replacing the mortise cylinder is not really an option.

It might look a tad unusual, but you could use 1/4" blocking rings/cylinder collars which would allow you to use your cylinders.

[globallockytoo]

so a primus cylinder doesnt come in 1-1/8"? that's odd

ahhh I understand now, thats new to me. Always something to learn around here

Go back and get 1 1/8" cylinders, and then use 1/8" inch mortise cylinder spacer ring.

I'd let this so-called locksmith know his great idear doesn't fit on your door and get something else

Those are decent deadbolts. I use SEVEN pin Best cylinders here which are long and I have a few of those locks. They work just fine with the right collars (and Adams-Rite cams).

What are the "right collars"? Getting those would seem the simplest solution. The cams seem correct already -- the combination works fine in another door I have that happens to be roughly a quarter inch thicker.

I don't believe the Schlage Primus is available in a shorter cylinder. Perhaps I should've gotten deadbolts that use rim cylinders instead, but I'd feel bad about sending the entire order back if this can be fixed with a spacer ring or a deeper collar, as has been suggested.

Personally, as a locksmith I detest adding any more spacer rings than needed. It has always seemed to me that the more complicated the
design, the more inherent flaws seem to exist and the easier to breach the system. There is a very good reason to use the shortest collar possible
and the fewest parts. Other folks may not agree, but I don't work on those people's locks.

One design flaw in particular plagues the lockset Your locksmith has selected for you. The short term is wrenching and making your mortise cylinders stick out where they can be grabbed and manipulated is bad news

[soksavik]

That's why a deeper sleeve/collar is probably a better answer than another spacer ring. Using the shortest sleeve possible is a good goal, but the fact of the matter is that the door is thin and the mortise cylinders are long. Selecting a shorter, less secure cylinder (would probably have to be a five-pin cylinder with no sidebar) is a cure worse than the disease IMHO.

Why do you feel that way? I have 5-pin medeco mortise cylinders in stock. Even if the door is a 1 3/8" the standard collars should work fine.
Having seen a break-in on one of these locks years ago i would recommend the use of a latch-guard also

BTW these type locks need to be fairly tight on the door, otherwise they will float around in the 2 1/8" mounting hole, and that will cause premature latch failure

I inherited a big box of these from my Dad when he retired (finally) and I don't Ever sell them. Once I had a client with a 2" backset, that is what they excel at, they make one weird size...
