Corbin Russwin 718F80-626 – Frequently Asked Questions

1) What is the Corbin Russwin 718F8 thimble pack actually used for?
The 718F8 is a two-piece thimble pack that goes with Corbin Russwin ML2000 Series mortise locks using knob trim. Thimbles are the small sleeve pieces that seat the knob trim against the lock spindle assembly. It is a replacement component, not a lockset, so you are buying it to service or rebuild existing ML2000 knob trim rather than to hang a new lock.
2) Does the 718F8 thimble pack work with lever trim or only knobs?
Knob trim only. The 718F8 is built for ML2000 knob designs, and both orderable configurations are knob versions: one for knob with rose trim and one for knob with M or N escutcheon trim. If your opening has ML2000 lever trim, this is the wrong part.
3) I have ML2000 knobs on escutcheon plates, not roses. Which thimble pack do I order?
Pick the M or N escutcheon version. The 718F8 comes in two trim-matched configurations: one for knob with rose trim and one for knob with M or N escutcheon trim. They are not interchangeable, so look at the door first and confirm whether the knob sits on a round rose or on a long escutcheon plate before you order.
4) Is the 718F8 a genuine Corbin Russwin part or an aftermarket copy?
It is a genuine OEM Corbin Russwin component for the ML2000 Series. That matters on mortise trim, because the ML2000 is a UL/cUL listed, UL10C positive pressure assembly rated for 3-hour fire doors up to 4 x 10 feet single or 8 x 10 feet pair. Substituting non-OEM trim parts into a fire-rated opening puts the listing in question at inspection.
5) What finishes does the 718F8 thimble pack come in so it matches the rest of my knob trim?
Four finishes: 605 bright brass, 612 satin bronze, 613 satin bronze oil-rubbed, and 626 satin chrome. All four are offered on both the rose-trim and the M/N escutcheon-trim versions. Match the BHMA finish number stamped or specified on the existing trim rather than judging by eye, since 612 and 613 look very different once installed.
6) Will the 718F8 fit my ML2000 lock if the door is thicker than standard?
The ML2000 platform is built around a 1-3/4 inch (44mm) door as standard, with optional thicknesses available from the factory. If your doors were ordered in a non-standard thickness, the trim and spindle components were specified to that thickness, so confirm what the original order called out before pulling a standard replacement thimble pack.
7) Does swapping the thimbles affect the handing of my ML2000 mortise lock?
No. Handing on the ML2000 is handled at the latchbolt, which is a patented quick reversible design that re-hands without disassembling the lock case. The thimble pack is trim hardware and carries no hand. Order it by trim style and finish only.
8) How many thimbles come in a 718F8 pack, and is that enough for one door?
Two pieces per pack, which covers both sides of a single opening with knob trim on each face. If you are standardizing across a run of doors in a building, count one pack per door leaf.
9) I am rebuilding an ML2000 knob opening. What else should I check while the trim is off?
Check the parts that carry the load. The ML2000 uses a 2-piece anti-friction latchbolt with a 3/4 inch (19mm) throw, a 9/16 inch (14mm) deadlocking auxiliary latch, and on deadbolt functions a one-piece stainless deadbolt with a 1 inch throw into an ANSI straight lip strike, 4-7/8 x 1-1/4 inches with 1-1/8 inch lip to center. Backset is 2-3/4 inches (70mm). If the latch is not projecting its full throw into the strike, the thimbles are not your problem.
10) Is the 718F8 suitable for high-traffic commercial doors or is it a residential part?
Commercial. It belongs to the ML2000 platform, which is ANSI/BHMA A156.13 Series 1000 Operational and Security Grade 1 and has been UL cycle tested to 14.5 million cycles. It is the right class of part for offices, schools, healthcare, retail, and multi-tenant residential corridors.
