Don-Jo 4550-626 – Frequently Asked Questions

1) Do I need to specify handing when ordering the Don-Jo 4550 hospital latch?
No handing to specify. The 4550 push/pull latch is fully non-handed and can be mounted with the handles up, down, or horizontal without any modification, so one part covers left-hand and right-hand openings. For a property manager stocking spares across a building, that means a single line item instead of a left/right split.
2) What backset does the Don-Jo 4550 hospital latch need in the door prep?
It runs a 5 inch backset, measured from the door edge to the center of the bore. That is deeper than the 2-3/8 and 2-3/4 inch backsets used on ordinary bored locksets, so an existing lock prep will not line up without new boring. Check the stile has room for a 5 inch backset before you commit.
3) Why use a push/pull hospital latch instead of a lever lockset on a patient room door?
A hospital latch lets staff open the door with a forearm, hip, or a full hand of supplies, which is the point on patient room, treatment room, and corridor doors. The Don-Jo 4550 is a push/pull latch, not a keyed lock, so it gives passage operation only. If the opening needs privacy or a keyed function, a lever lockset such as the Schlage ALX44 hospital privacy lock is the different product for that job.
4) What is the closest alternative to the Don-Jo 4550 hospital latch if the door already has a mortise lock body?
The Don-Jo 4550 is a push/pull latch with a 5 inch backset built for 1-3/4 inch doors. If the opening already carries a mortise lock case and you only need the paddles, the Schlage HL6-9000RK is a hospital push/pull mortise latch supplied as paddles only, less mortise lock, for 1-3/4 inch doors at a heavy duty level. The ABH 6600 Series is also a mortise lock hospital push/pull latch, specified with a 2-3/4 inch backset.
5) Which hospital push/pull latch should I specify if ADA compliance has to be stated on the submittal?
The Don-Jo 4550 is a commercial push/pull latch that can be mounted handles up, down, or horizontal without modification and is UL Listed. Where the submittal calls out ADA compliance by name, the ABH 6000 Series is a push/pull hospital latch with ADA compliance, and the ABH 6800 Series is a low profile hospital push/pull latch with ADA compliance.
6) I need a lower profile paddle than the Don-Jo 4550 because of a wall return. What are my options?
The Don-Jo 4550 has a 2-3/4 inch by 4-1/2 inch body with a lever projection of 3-1/4 inch. Where projection is tight, the ABH 6800 Series is a low profile hospital push/pull latch, and the ABH 6800Q is a quiet low profile hospital push/pull latch with a round cover.
7) Will the Schlage ALX44 work as a substitute for the Don-Jo 4550 hospital latch?
They solve different problems. The Don-Jo 4550 is a push/pull paddle latch with a 5 inch backset for 1-3/4 inch doors, operated by pushing or pulling the paddle. The Schlage ALX44 is a Grade 2 cylindrical non-keyed lever lock with a hospital privacy function at a medium duty level, so it gives you privacy on a lever trim rather than paddle operation. If the drawing says hospital privacy lock, the ALX44 is the match; if it says push/pull hospital latch, it is not.
8) If the opening needs to be locked rather than free-swinging, what should I use instead of the Don-Jo 4550?
The Don-Jo 4550 is a push/pull hospital latch and does not provide keyed security. For a secured opening in the same 1-3/4 inch door, the Schlage L9080BDC is a heavy duty mortise storeroom lock with a single cylinder non-deadbolt function and a disposable SFIC, and the Schlage L9070BDC is the heavy duty mortise classroom lock in the same family.
9) How far do the paddles on the Don-Jo 4550 stick out from the door?
Lever projection is 3-1/4 inches, with a body measuring 2-3/4 x 4-1/2 inches. Worth checking against corridor traffic patterns and anything mounted close to the door, like a wall stop or an adjacent frame in a tight alcove.
10) Can the Don-Jo 4550 be installed with the paddles pointing down for ADA-style forearm operation?
Yes. The same unit mounts handles up, handles down, or horizontal with no modification and no extra parts, so you pick the orientation on site rather than at the order. That flexibility is also useful when you are matching the paddle direction already used on the rest of the doors in a wing.
11) What is the difference between the Don-Jo 4550 and the Trimco 1562A hospital latch?
Both are hospital push/pull latches. The Don-Jo 4550 is non-handed and mounts with handles up, down, or horizontal without modification, with a 5 inch backset and 2-3/4 inch by 4-1/2 inch body. The Trimco 1562A is a tubular passage hospital latch specified levers down, at a heavy duty level.
12) Is the Kaba Ilco 459 push/pull paddle interchangeable with the Don-Jo 4550?
Both are push/pull paddle hardware. The Don-Jo 4550 is non-handed with a 5 inch backset, sized 2-3/4 inch by 4-1/2 inch for 1-3/4 inch doors, and offered in 626 Satin Chrome and 630 Satin Stainless Steel. The Kaba Ilco 459 Series is a push/pull paddle in its own right, so confirm the paddle prep and backset in the existing door before treating either as a drop-in for the other.
13) Which hospital latch is quieter for patient rooms than the Don-Jo 4550?
The Don-Jo 4550 is a brass push/pull latch finished in 630 Satin Stainless Steel or 626 Satin Chrome for healthcare corridors and patient rooms. Where latch noise is a concern on sleeping rooms, the ABH 6800Q is specified as a quiet low profile hospital push/pull latch with a round cover.
14) What finishes does the Don-Jo 4550 hospital latch come in?
Two: 630 Satin Stainless Steel and 626 Satin Chrome. Both read as a brushed silver tone, so either will blend with existing stainless or chrome hardware on adjacent openings, but the 630 is the usual pick for healthcare interiors where the rest of the hardware is stainless.
