Corbin Russwin 427F07-8 – Frequently Asked Questions

1) What exactly comes in the Corbin Russwin 427F07-8 packet?
The 427F07-8 is a trim alignment adapter packet that includes the E-Ring retaining element used with the working half trim adapter. It is the alignment/retention hardware only, not a lever, escutcheon, or complete trim set, so if the trim itself is broken you need the trim, not this packet.
2) Which Corbin Russwin mortise locks does the 427F07-8 adapter packet fit?
It is made for the ML2000 and ML2000HS mortise lock series as a genuine Corbin Russwin part. If the lock in your door is another series or another brand, this packet is not the part for it.
3) My ML2000 lever feels loose and sloppy on the door. Is this the part that fixes that?
If the play is coming from a worn or missing trim alignment adapter or a lost E-Ring on the working half, the 427F07-8 packet is the correct replacement. It positions and retains the working half trim so the lever sits where the factory intended. Play caused by a worn spindle, a failed lever spring cage, or a chewed-out lock case is a different repair.
4) Does the 427F07-8 go on the working half or the inactive half of the trim?
Working half only. It is engineered for the working half trim adapter of the ML2000/ML2000HS, which is the side carrying the operating lever or knob. The dummy or inactive half uses different components.
5) Will an aftermarket E-Ring work instead of ordering the 427F07-8?
The 427F07-8 is the OEM packet built by Corbin Russwin for this trim adapter, so it drops in at the original dimensions. A generic retaining ring may hold, but it is not the part the trim was toleranced around, and alignment on a mortise trim is what keeps the lever and spindle from binding.
6) Do I have to order anything else to complete an ML2000 trim repair?
Nothing else is bundled with the 427F07-8. It is a single-item packet ordered by model 427F07-8, so any levers, roses, escutcheons, spindles, or mounting screws you also need come separately.
7) Is this a commercial-duty part or a residential one?
Strictly commercial. The 427F07-8 is a replacement part for Corbin Russwin's commercial mortise lock line, and it turns up most often in offices, schools, healthcare, government buildings, and hospitality where ML2000 locks are the standard.
