Corbin Russwin 574F56-630 – Frequently Asked Questions

1) Will the Corbin Russwin 574F56 latch fit a door bored for a 2-3/4 inch backset?
No. The 574F56 is built to a 2-3/8 inch backset, which is the shallower of the two standard cylindrical backsets. If the cross-bore on your door sits 2-3/4 inches from the edge, this latch will not reach the chassis and you need the 2-3/4 inch backset version of the CK4400 latch instead. Measure from the door edge to the center of the 2-1/8 inch cross-bore before ordering.
2) What locks does the Corbin Russwin 574F56 throw-off latch work with?
It is a CK4400 Series part. The 574F56 is the throw-off latch for Corbin Russwin CK4400 cylindrical locksets, so it is the part you pull when the latch in an existing CK4400 is worn, binding, or damaged. It is not a universal latch and is not intended for mortise locks.
3) Square corner or radius corner latch faceplate, how do I know which one I need?
Look at the latch already in the door edge. The 574F56 has a square corner faceplate, which matches a door mortised with square corners, typically a metal door or a wood door prepped with a router and chiseled square. If the existing mortise has rounded corners, a square faceplate will leave gaps at the corners and you want the radius corner version of the CK4400 latch instead.
4) What finishes does the Corbin Russwin 574F56 CK4400 latch come in?
Four: 605 bright brass, 612 satin bronze, 613 satin bronze oil-rubbed, and 630 satin stainless steel. Match the latch faceplate to the lockset you are servicing, since the faceplate is the only part of the latch that stays visible on the door edge. 630 is the usual pick on commercial openings where the rest of the trim is satin stainless.
5) Can I use the 574F56 latch to repair a CK4400 lock without replacing the whole lockset?
That is exactly what it is for. The 574F56 is a genuine CK4400 replacement latch, so a maintenance tech can pull the lever trim and chassis, swap the latch unit in the door edge, and put the existing lockset back in service. Useful for property managers and MRO crews standardized on CK4400 across a building, since you keep the existing keying and trim and only change the failed component.
6) Does the 574F56 come with a strike plate?
The 574F56 is the latch unit itself, a throw-off latch with a square corner faceplate for the door edge. If the strike in the frame is also damaged or you are changing the corner style on the frame side, order the matching CK4400 strike separately. Reusing a serviceable existing strike is normal on a latch-only repair.
7) Is the Corbin Russwin 574F56 latch a commercial part or a residential one?
Commercial. It is a CK4400 cylindrical lock component intended for commercial door hardware, the kind of opening found in offices, schools, healthcare, and multi-tenant residential corridors rather than a homeowner's interior door. Residential-grade latches from hardware stores will not interchange with a CK4400 chassis.
