Corbin Russwin 688F17-7 – Frequently Asked Questions

1) Will the Corbin Russwin 688F17-7 latchbolt fit any mortise lock, or only the ML2000 series?
Only the ML2000. The 688F17-7 is a genuine Corbin Russwin latchbolt made for the ML2000 Mortise Lock Series, and it is a drop-in for that body only. Mortise latch cassettes are not interchangeable across series or brands, so if the lock case in your door is not an ML2000 this part will not seat or drive correctly.
2) Can I rebuild a worn ML2000 mortise lock instead of replacing the whole lock?
That is exactly what the 688F17-7 is for. Swapping the latchbolt restores latching action in an existing ML2000 mortise case, so a lock that no longer catches reliably can be serviced in place rather than pulling the whole body and re-prepping the door. It is sold as an OEM replacement part, not a complete lock.
3) I need a drive-in latch for an entry door, not a mortise lock part - what should I order?
For a bored door taking a drive-in latch, the Deltana DLE23875 is an adjustable entry-function drive-in latch for doors 1-3/8 inch to 2 inch thick, and the Deltana DLP23875 is the passage/privacy version with an adjustable backset of 2-3/8 inch or 2-3/4 inch. The Corbin Russwin 688F17-7 is a different kind of part - it is the replacement latchbolt that goes inside a Corbin Russwin ML2000 mortise lock case, not a standalone latch for a bored prep.
4) Can a Kwikset 84290 plainlatch be used in place of the Corbin Russwin 688F17-7?
No. The Corbin Russwin 688F17-7 is a genuine replacement latchbolt for the ML2000 Mortise Lock Series, meaning it installs inside an existing mortise lock case as a service component. The Kwikset 84290 is a square corner plainlatch with a 2-3/8 inch backset, a self-contained tubular latch unit that mounts in a bored door prep. A mortise lock case will not accept a tubular latch unit, so the two are not interchangeable - for an ML2000 case, use the 688F17-7.
5) Is this latchbolt rated for commercial traffic, or is it a residential part?
Commercial. The 688F17-7 is built for commercial door hardware duty and is the part Corbin Russwin specifies for servicing ML2000 locks in offices, schools, hospitals, retail, government buildings, multi-tenant residential and industrial facilities.
6) Do I get the lock body, trim or faceplate with the 688F17-7?
No. It is the latchbolt component only, a service part for an ML2000 mortise case already installed in the door. Trim, cylinder, spindle and faceplate stay as they are. If your faceplate is what is damaged rather than the bolt, order the faceplate separately.
7) Does the Corbin Russwin 688F17-7 carry a UL fire rating like the Kwikset RCAL latches?
The Kwikset 83521 RCAL plain latch and the Kwikset 83518 RCAL adjustable square drive latch are both listed as UL 3 hour latches for tubular lock applications. The Corbin Russwin 688F17-7 is described as a genuine OEM latchbolt for the ML2000 Mortise Lock Series, built for commercial door hardware service where the rating is carried by the ML2000 lock assembly it is installed into rather than by the loose latchbolt. If a specific fire label is required, verify it against the ML2000 lock being serviced.
8) What is the difference between the Corbin Russwin 688F17-7 and the Emtek LC9-DBLTCH deadbolt latch?
The Emtek LC9-DBLTCH is a motorized deadbolt latch in the EMPowered series, an electrified deadbolt component. The Corbin Russwin 688F17-7 is a mechanical latchbolt for the Corbin Russwin ML2000 Mortise Lock Series, supplied as an OEM replacement part to restore latching action in an existing mortise case. They serve different bolt functions - a spring latch versus a deadbolt - and belong to different lock platforms, so neither substitutes for the other.
9) Is a fire-rated latch needed, and does this Corbin Russwin part cover that?
For fire door openings you want a latch the manufacturer lists for that use. The 688F17-7 is described as an OEM ML2000 service latchbolt without a stated fire listing, so if a UL-listed latch is what your spec calls for on a bored residential-style door, Kwikset's 84290 square corner plainlatch with a 2-3/8 inch backset and the 83521 RCAL plain latch are listed as UL 3 hour.
10) For standardizing spare parts across a building, is one 688F17-7 the same part for every ML2000 lock?
The 688F17-7 is sold as a single part number with no size, hand or finish options to pick, so it stocks as one line item for ML2000 service work. Confirm each opening actually uses an ML2000 case before you build the spares kit, since other mortise series take different latch assemblies.
