Hager 3944 26D – Frequently Asked Questions

1) What backset does the Hager 3944 dead latch come in, 2-3/8 or 2-3/4 inch?
Both. The 3944 dead latch is ordered with either a 2-3/8 inch (60 mm) or 2-3/4 inch (70 mm) backset, so measure from the door edge to the center of the bore before you order. Those are the two standard commercial backsets, and picking the wrong one means the latch will not line up with the existing cross bore.
2) Will the Hager 3944 dead latch drop into my existing latch mortise?
Its faceplate measures 1-1/8 x 2-1/4 inches (29 mm x 57 mm). If the edge prep in your door was cut for that size faceplate, it drops in; a door routed for a larger faceplate will leave a gap, and a smaller pocket has to be enlarged. You also choose square corner or round corner faceplate to match how the mortise was routed.
3) Which Hager lock functions does the 3944 dead latch work with?
It supports the keyed functions in the 3400 Series lineup: 50 Office, 53 Entry, 70 Classroom, 80 Storeroom, 82 Institution, and 95 Classroom. The one exception is Corridor function, which this dead latch does not serve. So for an office suite, a classroom, or a storeroom door you are covered; a corridor-function lock needs a different latch.
4) Can I use the Hager 3944 dead latch on a fire rated door?
The 3944 dead latch is UL Listed, which is what a fire door assembly requires of its latching hardware. The lock body, closer, and door assembly all have to carry their own labels for the opening to remain rated, so the latch alone does not make a door compliant.
5) Square corner or round corner faceplate, which do I need?
That is a required choice on the 3944, and it is decided by your door, not by preference. Router-cut mortises have radiused corners and take the round corner faceplate; a chiseled or factory square pocket takes the square corner. Square corner is the standard offering on the 3400 Series dead latch, with round corner available.
6) Is this a residential deadbolt or commercial door hardware?
Strictly commercial. The 3944 is a dead latch for the Hager 3400 Series commercial lock line, built on a brass substrate for corrosion resistance in office, school, healthcare, retail, and multi-tenant openings. It is not a residential deadbolt and it is not a standalone lock, it is the latch unit that works behind the 3400 Series keyed lock.
7) What finishes can I get the Hager 3944 dead latch in to match my other doors?
Orderable finishes are 626 Satin Chrome and Black. The 3400 Series dead latch is also published across US3, US4, US10B, US26, US26D and BLK, so if your building is standardized on bright brass or oil rubbed bronze there is a matching option in the series. Note the latch face is largely hidden in the door edge, so most buyers match it to the strike and lock trim.
