Corbin Russwin 416F84-626 – Frequently Asked Questions

1) What does the Corbin Russwin 416F84 occupancy indicator actually do, and which lock does it go on?
The 416F84 is a sectional trim occupancy indicator for the Corbin Russwin ML2000 Series, and it's built specifically for the ML2029 mortise lockset on a 1-3/4 inch door. It gives a visual locked/unlocked status read at the trim, so staff or guests can tell room status without trying the lever. It is an accessory piece, not a complete lock, so the ML2029 lockbody and trim still have to be on the order.
2) Will the 416F84 indicator work with escutcheon trim instead of sectional?
No. The 416F84 is the sectional version. The ML2000 Series offers status indicator options on both sectional and escutcheon trim, so if your ML2029 openings are specified with escutcheon trim you need the escutcheon indicator instead, not this part. Match the indicator to the trim style already on the door.
3) My guest room doors are 1-3/8 inch. Can I still use this indicator?
Not this one. The 416F84 is built for 1-3/4 inch (44mm) doors, which is the ML2000 standard thickness. The series does offer optional door thicknesses, but those are ordered as a different configuration. On a 1-3/8 inch door the indicator and trim spacing won't line up.
4) Does adding an occupancy indicator to an ML2029 affect the fire rating of the door?
The ML2000 mortise lock platform is UL/cUL listed to UL10C positive pressure and carries a 3-hour fire door rating up to 4' x 10' single or 8' x 10' pair. The indicator is a factory trim option within that same ML2000 platform, so it is used on those rated openings as part of the listed assembly. It also meets ADA A117.1 and is California State Fire Marshal listed.
5) What backset and door prep does the ML2029 with this indicator need?
Standard ML2000 prep: 2-3/4 inch (70mm) backset, with a heavy-gauge steel lockcase measuring 5-7/8 x 4 x 15/16 inches and an 8 x 1-1/4 inch armored front. Trim spacing is 3-5/8 inch center to center from knob/lever to cylinder and 2-7/16 inch from knob/lever to thumbturn. If your existing door already has an ANSI mortise pocket cut for a 2-3/4 inch backset, the prep carries over.
6) Will my existing strikes work if I put ML2029 locks with indicators on these doors?
The ML2000 uses an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with a 1-1/8 inch lip-to-center. The latchbolt throws 3/4 inch (19mm) and the deadbolt throws 1 inch (25mm), with a 9/16 inch (14mm) deadlocking auxiliary latch. If the frame already has a standard ANSI 4-7/8 inch strike prep, it will latch; a T-strike or non-ANSI frame prep needs to be changed.
7) What finishes does the Corbin Russwin 416F84 indicator come in, and will it match my existing ML2000 trim?
Two finishes: 612 Satin Bronze and 626 Satin Chrome. Both are standard BHMA finish codes, so if the ML2029 trim on your other doors was specified 612 or 626 the indicator will match across the fleet. If your building is on a different finish code, this part won't blend in.
8) Is the ML2029 lock behind this indicator strong enough for a hotel corridor?
It is ANSI/BHMA A156.13 Series 1000, Operational and Security Grade 1, which is the top commercial grade, and it is UL cycle verified at 14.5 million cycles. The latchbolt is a two-piece anti-friction design with a 3/4 inch (19mm) throw, which cuts the force needed to close against a closer and a latched frame. That combination is what hotel, healthcare and multi-tenant corridors are specified on.
9) Do I have to specify handing when ordering ML2029 hardware with this indicator?
The ML2000 ships handed, but the latchbolt is a patented Quick Reversible design that re-hands without taking the lock case apart. Practically, that means a wrong-hand delivery isn't a return, and a locksmith carrying one lock can cover either swing on a service call.
10) Can I key ML2029 locks with indicators into my existing master key system?
Yes. The ML2000 works with new or existing Corbin Russwin key systems and accepts most other manufacturers' cylinders, so you can keep whatever system the building already runs. Factory standard is a brass 6-pin L4 keyway cylinder, 0-bitted, if you're keying on site.
