Hager 3945 26D – Frequently Asked Questions

1) What size mortise does the Hager 3945 faceplate need in the door edge?
The faceplate measures 1-1/8" x 2-1/4" (29 mm x 57 mm), so the edge of the door has to be routed to that footprint. That is the standard small commercial latch face, so it usually matches an existing edge mortise on a cylindrical prep without rework.
2) Does this Hager latch lock, or is it passage only?
Passage only. The 3945 is a Function 10 passage latch, so the bolt retracts freely from both sides with no locking or keying. For an opening that has to secure, you need a lock function latch, not this one.
3) What is the closest cross-brand equivalent to the Hager 3945 spring latch at a 2-3/8 inch backset?
The Falcon A57420-000 B Series springlatch is the nearest cross-brand counterpart, also built for a 2-3/8 inch backset. The difference to check before you order is the faceplate: the Hager 3945 uses a 1-1/8 inch by 2-1/4 inch faceplate, while the Falcon A57420-000 carries a 1 inch face. If the door is already routed for the wider Hager faceplate, dropping in the narrower Falcon face will leave the mortise pocket exposed, and the reverse requires widening the router cut. Backset is the same, so the cross-bore and latch bore locations carry over.
4) Do I have to pick square corner or round corner when ordering the Hager 3945?
Yes, faceplate corner style is a required choice: square corner or round corner. Match whatever is already routed in the door edge. Square is the standard on the 3400 Series; round corner suits a door prepped with a radiused mortise.
5) Is there another brand of 2-3/8 inch spring latch I could use instead of the Hager 3945?
The Falcon A57420-000 B Series springlatch is also a 2-3/8 inch backset unit, but it uses a 1 inch face rather than the Hager's 1-1/8" x 2-1/4" faceplate. That is a different edge prep, so it is not a straight swap into a mortise cut for the Hager face unless the door edge is re-routed or the plate covers it.
6) Can I use the Hager 3945 as a replacement latch in an existing 3400 Series knob or lever set?
That is exactly what it is for. The 3945 is a 3400 Series component, so it keeps the series' consistent function and appearance across a building's openings, which is what property managers want when they are replacing worn latches one door at a time rather than swapping whole locksets.
7) Can a Falcon B Series springlatch be swapped into a door prepped for the Hager 3400 Series latch?
Mechanically the backset matches - the Falcon A57420-000 is a 2-3/8 inch springlatch, the same backset the Hager 3945 is built to - so the bore spacing in the door does not change. What does change is the face. The Falcon unit has a 1 inch face against the Hager 3945 1-1/8 inch by 2-1/4 inch faceplate, so the edge mortise and the strike alignment need to be verified rather than assumed. On a new door being prepped from scratch either can be specified; on a retrofit into an existing Hager 3400 prep, staying with the 3945 avoids rework on the edge cut.
8) If the opening needs a locking latch rather than passage, is the Falcon B Series springlatch the right substitute for the Hager 3945?
No - a springlatch on either side is a latching component, not a locking one. The Hager 3945 is a passage function latch, meaning the latch retracts freely from both sides with no locking action, and the Falcon A57420-000 is likewise a B Series springlatch rather than a deadlatch or deadbolt. Swapping one springlatch brand for the other does not add security to the opening. For a door that must lock, the locking function has to come from the lockset or a separate deadbolt, not from changing the spring latch.
9) What finishes can I get the Hager 3945 spring latch in?
Two orderable finishes: 626 satin chrome and black. Satin chrome is the usual match for US26D lock trim on commercial openings; black suits dark or bronze-tone hardware. The latch face is the only part that shows once the door is closed, so match it to the strike and the lockset trim.
10) What is the Hager 3945 latch made of, and will it hold up in a high traffic corridor?
Brass substrate. Brass resists corrosion better than plain steel, which is why it gets specified for high cycle passage openings and damp areas like locker rooms and service corridors. Passage latches take constant retraction, so the material is the main wear consideration here.
