Dormakaba 34266-05-01 – Frequently Asked Questions

1) What exactly is the Dormakaba 34266-05-01 part, and is it a complete lock?
It is the outside knob only, a lock trim component, not a complete lockset. The 34266-05-01 is the exterior-facing knob for Sargent Large Format Interchangeable Core (LFIC) lock assemblies, sold as a replacement part in Antique Brass. If your lock body is bad, this knob won't fix it; it restores the outside trim and knob function on an otherwise working assembly.
2) Will the 34266-05-01 knob accept my Sargent large format interchangeable core?
Yes. The knob is built for Sargent LFIC cylinder systems, so a large format interchangeable core swaps in without pulling the lock body. It will not take a small format interchangeable core (SFIC) or a standard mortise cylinder; those are different core geometries, so verify the core in hand is the large format Sargent type before ordering.
3) Is this the inside knob or the outside knob?
Outside only. The 34266-05-01 is the exterior-facing trim that carries the keyed core. If the damaged knob is on the room side, this isn't the part; you need the matching inside trim for that lock.
4) What should I use if the door has a lever opening instead of a knob?
The Dormakaba 34266-05-01 is an outside knob trim built for Sargent LFIC cylinder systems, so it will not convert an opening to lever operation. For a lever, the Corbin Russwin 483F80 is a Grade 1 ML2000 Series outside lever and spindle for a 1-3/4 inch thick door in a corridor/dormitory function. Choose the 34266-05-01 when you are restoring knob trim on an existing Sargent LFIC assembly, and the 483F80 when the opening is an ML2000 mortise lock needing lever trim.
5) Is the Antique Brass finish the only option on the 34266-05-01?
Yes, the 34266-05-01 is a single-finish part number: Antique Brass, factory applied. If the rest of your openings are bright chrome, satin nickel, or oil-rubbed bronze, this knob will not match, and you would need the equivalent Dormakaba knob in that finish instead.
6) Is a knob like this suitable for high-traffic commercial doors, or is it residential grade?
It is a commercial-grade component, built to Dormakaba's commercial product standards, and is used in offices, schools, healthcare, government buildings, multi-tenant residential, retail, and warehouse facilities. Keep in mind that in many jurisdictions a knob is not accepted on egress or accessible openings where a lever is required, so for those doors a lever trim is the right call.
7) Do I need to order anything else to swap an outside knob on an LFIC lock?
The 34266-05-01 covers the outside knob itself. You reuse your existing large format core and keys, since the knob is made to accept the Sargent LFIC core. If the core is worn or you are rekeying at the same time, order the core separately; it is not part of this knob. Inside trim, spindles, and lock body parts are also separate part numbers.
8) Can I use the 34266-05-01 to standardize trim across a whole building?
It works as a service part rather than a standardization program. Because it is a single model in one finish and is tied to Sargent LFIC keying, it fits buildings already running LFIC cores on Dormakaba/Sargent hardware, which is where keying stays consistent across doors. For openings on a different lock platform or finish, matching means specifying the trim for that platform, not forcing this knob onto it.
