Corbin Russwin 599F91-626 – Frequently Asked Questions

1) Will the Corbin Russwin 599F91 latch work in a standard 2-3/4 inch backset mortise lock case?
No. The 599F91 is a 2-3/8 inch backset spring latch and will not work with a standard 2-3/4 inch chassis. Measure from the door edge to the center of the spindle hole on the lock case you are servicing before you order; if that comes out at 2-3/4 inches, this is the wrong part.
2) Is the 599F91 the correct replacement latch for a Corbin Russwin lock ordered with the B238 option?
Yes. The 599F91 is the latchbolt supplied as standard with the B238 option, so on a lock built that way it is a direct drop-in replacement.
3) What size is the faceplate on the Corbin Russwin 599F91 spring latch?
The front measures 2-1/4 by 1 inch with square corners, so it drops into an existing square-corner mortise pocket of that size without recutting the door edge. If the door is prepped for a radius-corner front, the edge prep will not match.
4) What does the 599F91 latchbolt actually do in the lock?
It is the springlatch, the beveled bolt that retracts on the strike and snaps back out when the door closes. It handles everyday latching only, not deadlocking, so if your lock case has a separate deadbolt that is a different component.
5) Is this latch a whole mortise lock or just the bolt assembly?
Just the latch component. The 599F91 is an OEM replacement latchbolt for Corbin Russwin mortise lock cases, not a complete lockset. You keep your existing case, trim, and cylinder and swap only the latch.
6) What finishes does the 599F91 latch come in, and does it need to match the rest of my lock trim?
Four finishes: 612 satin bronze, 613E dark oxidized satin bronze equivalent, 626 satin chrome, and BSP black suede powder coat. Only the front is visible once the lock is in the door, so match it to the armor front and edge trim on the existing openings rather than to the lever finish if those differ.
7) Is the 599F91 spring latch rated for commercial traffic in schools and healthcare buildings?
It is a commercial-grade component built to Corbin Russwin's commercial mechanical lock standards, used in offices, schools, healthcare, retail, industrial, multi-tenant residential, and government buildings. For standardizing across a facility, note the 2-3/8 inch backset restriction, since many commercial mortise preps run 2-3/4 inches.
8) Does the 599F91 latch need to be handed?
It is a plain springlatch, and the bolt bevel is what determines which way the door swings. Check the bevel direction against the latch you are pulling out and reverse or orient it as the lock case requires before you reassemble.
