Corbin Russwin 120F76-8 – Frequently Asked Questions

1) Can I use the 120F76-8 dust box with a different brand of lock or strike?
Treat it as a 679L25 part. It's dimensioned for that Corbin Russwin strike on CL3700 cylindrical locks, so pairing it with another manufacturer's strike is a gamble on pocket size and screw hole layout. If you are working on a residential deadbolt instead, a generic box like the Kwikset 81231-001 metal strike dust box or the Kwikset 81640 strike box is the right shelf to look on.
2) Will a deadbolt strike plate work in place of the Corbin Russwin 120F76-8?
No. A strike plate and a strike dust box are two different pieces. The Corbin Russwin 120F76-8 is the dust box that lines and covers the strike pocket behind the 679L25 strike. Parts such as the Deltana SP2753 deadbolt strike plate at 2-3/4 inch by 1-1/4 inch steel, or the Emtek 83223 standard deadbolt strike plate with square corners, are the visible face plate on the frame, not the box behind it.
3) What does the Corbin Russwin 120F76-8 dust box actually do in the frame?
It's the metal cup that sits behind the strike in the frame pocket. The 120F76-8 lines the mortised pocket so the latch has a clean cavity to throw into, keeps debris and insulation out of that pocket, and gives the strike a finished look where it meets the frame. It is a replacement part only, not a lock or a strike plate.
4) Do I need a new strike plate too, or just the dust box?
The 120F76-8 is the dust box on its own. If your 679L25 strike plate is still sound, reuse it and drop this box into the pocket behind it. If the strike face is bent or the screw holes are stripped, order the strike as well; this part will not cover a damaged strike face.
5) I'm a property manager standardizing frames across a building. Is this the same box for every CL3700 opening?
Where the openings use the 679L25 strike, yes, the 120F76-8 is the matching box across them. Openings in the same building fitted with a different Corbin Russwin strike number will take a different box, so check the strike stamped on each frame before ordering in quantity. It is sold as a single item.
6) What's the difference between a strike box and an adjustable strike like the Kwikset full round?
Two different jobs. The 120F76-8 is a pocket liner that sits behind the strike; it does nothing for latch alignment. An adjustable strike such as the Kwikset 80318 full round adjustable strike or the Kwikset 81825 6-way adjustable deadlatch is a face part that lets you shift the catch point when the door isn't lining up. If your problem is a door that won't latch, the dust box isn't the fix.
7) For a commercial building standard, should I stock the 120F76-8 or a residential-style strike box?
The Corbin Russwin 120F76-8 is a commercial replacement part built to Grade 2 standards for the CL3700 cylindrical lock series, which is what keeps a CL3700 opening OEM-matched across a facility. The Kwikset 81231-001 metal strike dust box and Kwikset 81640 strike box are deadbolt strike parts and serve a different opening, so they would sit alongside rather than replace the 120F76-8 in a CL3700 standard.
8) I have an ASA-prepped frame - does the Corbin Russwin 120F76-8 fit, or do I need something else?
The Corbin Russwin 120F76-8 is specified to the 679L25 strike within the CL3700 cylindrical lock series, so match it to that strike rather than to a generic frame prep. For an ASA frame cutout, the Codelocks ASA strike plate is an ASA-series strike plate in a stainless steel finish and is intended for that prep.
9) My latch is not lining up with the strike - is the 120F76-8 adjustable?
The Corbin Russwin 120F76-8 is a fixed OEM dust box that matches the 679L25 strike pocket in the CL3700 series, so alignment comes from the frame prep. If you need adjustment to chase a misaligned latch, the Kwikset 80318 is a full round adjustable strike and the Kwikset 81825 is a 6 way adjustable deadlatch, both deadbolt strike plate parts.
10) Is the Corbin Russwin 120F76-8 rated for commercial use?
Yes. It is a Grade 2 component intended for commercial door hardware, which is where the CL3700 cylindrical series lives: offices, schools, healthcare, retail, government buildings, multi-tenant residential and warehouse work.
