Calibre Door Closers LS4001-118-AL – Frequently Asked Questions
1) What cylinder backset does the Calibre LS4001 deadlatch come in, and which one do I need?
The LS4001 deadlatch is built in 1-1/2 inch, 1-1/8 inch, and 31/32 inch cylinder backsets, and the backset has to match the distance from the edge of your aluminum stile to the center of the existing cylinder hole. Measure that on the door before ordering, because the backset is fixed in the lock body and cannot be adjusted in the field. For reference, the related LS-3000 is made in 1-1/8 inch backset only.
2) Which cylinder works with the Calibre LS4001 deadlatch?
It takes a standard 1-5/32 inch mortise cylinder, key or thumbturn, with an AR MS-type cam. That is the common storefront mortise cylinder, so if you are keying a building alike you can order the cylinders separately in your existing keyway. Cylinders are not part of the latch itself, so budget for them on the order.
3) Do I have to specify handing for the Calibre LS4001 deadlatch?
No. The LS4001 is field reversible, so one part covers left and right hand openings and you set the latch direction at install. That makes it easier to stock a single item across a property with mixed swings.
4) Is the LS4001 a deadbolt or a latch?
It is a deadlatch, a mortise lock that latches automatically when the door closes and is deadlocked against being jimmied, rather than a throw-by-key deadbolt. The bolt is 5-ply laminated steel with a hardened roller pin set in a case hardened center ply to resist sawing.
5) Which Calibre LS4001 finish and backset combinations can I actually order?
The stocked pairings are AL aluminum and DU storefront bronze, each in 1-1/8 inch and 31/32 inch backset. Pick the backset off the door first, then the finish to match the frame.
6) What finishes does the Calibre LS4001 deadlatch come in for matching storefront doors?
Three painted finishes: AL satin aluminum, BK black, and DU storefront bronze. AL and DU are the two that cover most clear-anodized and dark bronze aluminum storefronts. Because the faceplate is flat, it sits against a flat-face stile rather than a radius-face door.
7) Is the Calibre LS4001 deadlatch suitable for a high-traffic commercial entrance?
Yes, it is a commercial-rated mortise deadlatch for aluminum storefront entrances, not a residential lock. The laminated steel bolt with a hardened roller pin is the construction used where doors get pulled hundreds of times a day and forced entry is a concern.
