Corbin Russwin 586F18-626 – Frequently Asked Questions

1) Will the Corbin Russwin 586F18 latch work in a door already bored for a 2-3/4 inch backset?
Yes. The 586F18 is the 2-3/4 inch backset latch, which is the standard backset on the CL3500/CL3800 cylindrical locksets. The faceplate is a square corner front measuring 2-1/4 x 1-1/8 inches. If your opening was prepped for one of the optional backsets, 3-3/4 inch or 5 inch, this is the wrong part and you need the latch matched to that backset instead.
2) Do I need to order a left hand or right hand version of the 586F18 latch?
Neither. The 586F18 latch is field reversible, so one part covers both hands and you flip it on the job rather than ordering by handing. The CL3500/CL3800 locksets themselves are non-handed as well, with the exception of FZD trim.
3) Which Corbin Russwin locks does the 586F18 latch fit?
It is a replacement latch for the CL3500 and CL3800 Series cylindrical locksets. It is not a universal latch, so don't plan on dropping it into a mortise lock or another manufacturer's cylindrical chassis.
4) Is this latch fire rated for a labeled door?
The 586F18 is the standard latch with a 1/2 inch stainless steel latchbolt throw. The CL3500/CL3800 platform offers an optional 3/4 inch fire latch, and that is the one specified for fire door applications. If your opening carries a label, order the 3/4 inch fire latch rather than this one.
5) My latch faceplate has rounded corners. Can I use the 586F18?
Not without changing the door prep. The 586F18 has a square corner front, 2-1/4 x 1-1/8 inches. Dropping a square corner plate into a mortise routed for a radius corner leaves a visible gap at the corners. Order the square corner version only if the existing pocket is square, or plan on re-routing.
6) Will a 1/2 inch throw latch still catch in my existing ANSI strike?
Yes, with a standard ANSI strike prep. The CL3500/CL3800 strike is a wrought brass or stainless steel ANSI curved lip strike, 4-7/8 x 1-1/4 inches with 1-1/4 inch lip to center, and the 1/2 inch stainless latchbolt is sized to that. The latch also carries a deadlocking auxiliary latchbolt, so the main bolt can't be manipulated once the door is closed.
7) What door thickness does the CL3500/CL3800 latch setup handle?
1-3/4 inch (44mm) and 2 inch (51mm) are standard, with an optional build for doors over 2 inches up to 2-1/4 inch (57mm). The latch itself is the same; thickness is handled by the chassis and through-bolt hardware.
8) What finishes does the 586F18 latch come in, and will it match my existing lever trim?
Five finishes: 605 bright brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, and 626 satin chrome. For a fleet of doors, match the number to what's stamped on the lock you're servicing. Only the faceplate shows once installed, so the finish choice is about that visible front against the edge of the door.
9) Is this a Grade 1 commercial part or something lighter duty?
Commercial. The CL3500/CL3800 cylindrical lockset it serves is certified to ANSI/BHMA A156.2 Series 4000, Grade 1, and is UL-cUL listed, meets ANSI A117.1 accessibility, and is listed by the California State Fire Marshal. That is the spec level for schools, hospitals, and municipal buildings where the lock is cycled hard.
10) Can I replace just the latch, or do I have to buy a whole new lockset?
Just the latch. The 586F18 is sold as a genuine replacement part for the CL3500/CL3800 cylindrical locks, so a worn or damaged latch unit can be swapped without pulling the chassis, levers, or cylinder. That is the usual repair when the bolt is dragging or the auxiliary latch has failed but the lock body is fine.
11) Does the 586F18 latch work on the electrified CL33900 locks too?
The CL33900 electrified option runs on the same CL3500/CL3800 cylindrical platform, at 12 or 24VAC/VDC with a continuous duty solenoid drawing 250mA at 12V or 150mA at 24V, and uses an ElectroLynx 8-pin connector. The electrification is in the chassis, not the latch, so the mechanical latch and its 2-3/4 inch backset prep are unchanged. Confirm the backset on the installed lock before ordering.
