Corbin Russwin 599F92-626 – Frequently Asked Questions

1) Will the Corbin Russwin 599F92 latch fit a door bored on a 2-3/8 inch backset?
Yes, that is exactly what the 599F92 is cut for. It is the 2-3/8 inch backset version of the CL3500/CL3800 cylindrical latch. The CL3500/CL3800 locksets are built around a 2-3/4 inch backset as standard, with 2-3/8, 3-3/4 and 5 inch offered as options, so order this one only when the cross bore centers 2-3/8 inches from the door edge. Measure from the door edge to the center of the 2-1/8 inch chassis bore before you commit.
2) Does the 599F92 latch have to be ordered left hand or right hand?
No handing to specify. The 599F92 deadlocking latch is field reversible, so one part covers both left and right hand doors and you can flip it on site. The CL3500/CL3800 chassis itself is non-handed as well, which is why a single latch part number serves the whole series.
3) What size edge bore does this Corbin Russwin deadlocking latch need in the door?
The 1/2 inch throw latchbolt on the 599F92 works in both 7/8 inch and 1 inch edge bore preps, so it drops into either of the two common cylindrical edge preps without re-drilling. The faceplate is the 1 inch wide square corner style, and the standard CL3500/CL3800 front measures 2-1/4 x 1-1/8 inches.
4) Will this latch work with my existing strike, or do I need a new one?
The latchbolt throws 1/2 inch, same as the factory CL3500/CL3800 latch, so an existing strike set for that series will still catch. The series strike is the ANSI curved lip type, 4-7/8 x 1-1/4 inches with a 1-1/4 inch lip to center. If your frame has a 4-7/8 inch ANSI strike prep, you are fine; if the door has shifted or sagged, replace the strike at the same time rather than filing the lip.
5) Can I use the 599F92 latch on a fire rated door?
The CL3500/CL3800 cylindrical locksets this latch belongs to are UL/cUL listed for 3-hour fire doors up to 4 x 10 feet, and the series is listed to NFPA 80. Keep the assembly complete and original to the series, since substituting a non-series latch into a listed lockset voids the label.
6) What door thickness and stile width does the CL3500/CL3800 latch suit?
Standard range is 1-3/8 to 1-7/8 inches (35 to 48mm), with thicker doors up to 2-1/4 inches handled by an option on the lockset. Minimum stile is 4-1/2 inches (114mm), so a narrow aluminum stile door will not take this chassis, you would need a narrow stile lock instead.
7) Which finish of the 599F92 latch should I order to match my existing hardware?
Eleven finishes are offered: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, 629 bright stainless, 630 satin stainless, and 722 black oxidized bronze oil-rubbed. Only the faceplate shows once installed, so match it to the lock and strike already on the door. In most commercial buildings that is 626 or 630.
8) What does a deadlocking latch do that a plain spring latch does not?
A deadlocking latch carries a small auxiliary plunger alongside the main bolt. When the door closes, the plunger rides the strike and locks the latchbolt against being pushed back, which defeats loiding with a card or shim. On an exterior or tenant entry door that is the latch you want. The 599F92 is the deadlocking latch for Corbin Russwin CL3500/CL3800 cylindrical locksets, with a stainless steel bolt.
9) Can I swap just the latch instead of replacing the whole Corbin Russwin lockset?
Yes. The 599F92 is a replacement latch unit for the CL3500/CL3800 cylindrical series, so a worn or sticking bolt is a parts swap, not a lock swap. Pull the lever and chassis, slide the old latch out of the edge bore, and drop in the matching backset. Just confirm the backset, since these locks were built in 2-3/8, 2-3/4, 3-3/4 and 5 inch.
10) Is this latch suitable for a high traffic commercial opening or is it a residential part?
It is a commercial component. The 599F92 is built for the CL3500/CL3800 cylindrical lever locksets used in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings, and the series prep follows ANSI/BHMA A156.115 door prep with ADA A117.1 compliant operation.
