Corbin Russwin DL4111 626 – Frequently Asked Questions

1) Does the DL4111 deadlock use a 2-3/4 inch backset, and will it drop into an existing mortise pocket?
Backset is 2-3/4 inches, the standard commercial mortise backset, so it lines up with a door already prepped for a standard mortise lock body. The deadbolt throws a full 1 inch, and the supplied strike measures 3-1/2 x 1-1/8 inches. If the existing frame strike prep is a different size, plan on the included strike or a frame-specific option rather than reusing what is in the jamb.
2) Does the DL4111 have a thumbturn on the inside, or is it key-only?
Key one side only, blank on the opposite side. There is no thumbturn and no inside release of any kind, so the door cannot be unlocked from the blank face. That makes it right for storefront back doors, stockrooms, gates and utility openings that are secured from outside and never need egress through that door. If someone can be inside the space, this is the wrong function and you want a deadlock with a turn or an inside cylinder instead.
3) Can I get the DL4111 deadlock less cylinder so it takes my building's interchangeable core?
Four cylinder choices are offered. The standard is a conventional 6-pin cylinder in the L4 keyway, supplied 0-bitted with two nickel silver keys. If you key the building yourself, order CL6 (less core, LFIC 6-pin Corbin Russwin), CL7 (7-pin IC less core), or LC (less conventional cylinder). The three less-cylinder options ship without the plug so you drop in your own core or cylinder and the deadlock joins the existing key system rather than adding a new key to the ring.
4) Can the DL4111 deadlock be master keyed into an existing Corbin Russwin system?
Yes, when ordered with the conventional 6-pin L4 cylinder it supports master keying, construction master keying, 7-pin conventional, interchangeable core, security cylinders, visual key control, concealed key control and pyramid keying in both conventional and IC. For a property with an existing Corbin Russwin system, the cleanest route is a less-core option (CL6 for LFIC 6-pin, CL7 for 7-pin IC) and your own cores, which keeps keying entirely under your control.
5) What finishes does the Corbin Russwin DL4111 mortise deadlock come in?
Seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, and BSP black suede powder coat. For matching a building already standardized on Corbin Russwin, 626 satin chrome is the usual commercial default and 613 the dark bronze match. Every finish is offered with all four cylinder options, so a keying preference does not narrow the finish choice.
6) Do I have to order the Corbin Russwin DL4111 deadlock handed?
No handing to specify. The DL4111 is non-handed, so the same lock works on a left or right hand door and you do not need to know the swing before ordering. The front plate adjusts for flat or beveled edges, which covers the other variable that usually forces a handed part.
7) Is the DL4111 deadlock ANSI Grade 1 and what ANSI function number is it?
The DL4111 is built to the ANSI/BHMA E6080 Series designation, which is the mortise deadlock category under A156.13. For a spec writer or a facilities buyer standardizing a campus, E6080 with a 1 inch throw steel deadbolt and a 2-3/4 inch backset is the line to put on the schedule.
8) Will a 1 inch deadbolt throw satisfy a commercial security spec?
The bolt is steel with a hardened pin and throws a full 1 inch, which is the throw most commercial security specs call for on a deadlock. The hardened pin resists sawing at the bolt. Pair it with the 3-1/2 x 1-1/8 inch strike supplied, and confirm your frame has enough depth behind the strike to take the full inch of bolt.
9) Should I use a mortise deadlock or a surface-mounted deadbolt on a commercial door?
A mortise deadlock like the DL4111 goes into a pocket routed in the door edge, so the lockcase is concealed inside the door and only the front plate and cylinder show. That takes a door that is already mortised or one you can machine, and a 2-3/4 inch backset prep. A surface or tubular deadbolt is faster on a door with no mortise pocket, but it does not give the same case protection. If the door already has a mortise pocket from an old lock, the mortise deadlock is the like-for-like path.
10) Is the strike included with the Corbin Russwin DL4111, or do I order it separately?
A wrought brass or bronze strike measuring 3-1/2 x 1-1/8 inches comes with the deadlock. Optional strikes are available for other frame conditions, so if you are working into an aluminum frame, a double door, or an existing deep prep, specify the strike that suits rather than assuming the standard one drops in.
11) What size is the front plate on the DL4111 mortise deadlock?
The front measures 4-5/8 x 1-1/8 inches and is offered in brass, bronze or stainless steel. That is the visible footprint on the door edge, so if you are replacing an older mortise deadlock, check the existing edge cutout against those numbers before you commit. The front adjusts for flat or beveled doors, 1/8 inch of bevel in 2 inches.
12) Is the DL4111 deadlock rated for high-traffic commercial use, or is it a residential lock?
Commercial only. The lockcase is heavy wrought steel with a zinc dichromate finish for corrosion resistance, the bolt is steel with a hardened pin, and it is built to the ANSI/BHMA E6080 Series. It is used on office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities. For a property manager standardizing across a portfolio, this is the level of hardware that holds up on doors that see daily use.
