Schlage 09-402 41 626 – Frequently Asked Questions

1) Will the Schlage 09-402-KNOBS knob kit work on a Schlage L Series mortise lock?
Yes. The 09-402-KNOBS kit is built for Schlage L Series interior lock trim and fits without modification. It is the interior (inside) trim knob, so it replaces the knob on the room side of an L Series mortise lock, not the outside trim.
2) What comes in the Schlage 09-402-KNOBS kit, and do I need anything else to install it?
The kit ships with the knob, a bushing, a mounting plate, a screw pack, and a spanner wrench. That covers the fasteners and the tool for the spanner nut, so a service tech does not have to source separate hardware for a straight knob swap on existing L Series interior trim.
3) What is the difference between the 41 knob and the 42 knob on the Schlage L Series trim kit?
They are two different knob designs offered on the same L Series interior replacement kit, ordered as a Lever Style selection: 41 Knob or 42 Knob. Match the number to what is already on your other L Series doors so the replacement looks identical across the building. The 41 knob is offered in eleven finishes including 643E Aged Bronze; the 42 knob is offered in ten.
4) Can a Corbin Russwin 483F80 lever be used to replace a knob on a Schlage L Series mortise lock?
No. The Schlage 09-402-KNOBS kit is a knob replacement engineered specifically for Schlage L Series interior lock trim, and its bushing, mounting plate and screw pack are matched to that chassis. The Corbin Russwin 483F80 is an outside lever and spindle for the Corbin Russwin ML2000 Series, a different mortise lock family. Keep each manufacturer's trim on its own chassis - stay with the 09-402-KNOBS for L Series interior trim, and use the 483F80 only on an ML2000 mortise lock.
5) What finishes does the Schlage 09-402 L Series knob kit come in?
Eleven finishes in total: 605 Bright Brass, 606 Satin Brass, 609 Antique Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 619 Satin Nickel, 625 Bright Chrome, 626 Satin Chrome, 629 Bright Stainless Steel, 630 Satin Stainless Steel, and 643E Aged Bronze. 643E is offered with the 41 knob. For a facility standardizing hardware, 626 Satin Chrome and 630 Satin Stainless are the usual commercial picks.
6) My L Series knob is loose and spinning. Does this kit fix it?
It should, as long as the mortise chassis itself is sound. The kit supplies a new knob, bushing, mounting plate, and screw pack, which are the parts that wear or work loose on an L Series interior trim assembly, plus the spanner wrench needed to retighten the knob correctly. If the lock body is failing, you are replacing the chassis, not the trim.
7) I need to change an interior knob to a lever for ADA compliance - what do I order instead of the Schlage 09-402-KNOBS?
The 09-402-KNOBS kit supplies knob trim in 41 Knob and 42 Knob styles, so it will not convert an opening to lever operation. For a lever-operated mortise opening, the Corbin Russwin 483F80 is an outside lever with spindle for ML2000 Series mortise locks, sized for a 1-3/4 inch thick door. Note that it fits the Corbin Russwin ML2000 chassis rather than a Schlage L Series lock, so the lever route means matching the lock family as well as the trim.
8) Is the Schlage 09-402-KNOBS kit rated the same commercial grade as a Corbin Russwin 483F80?
The 09-402-KNOBS is a commercial replacement knob kit for Schlage L Series interior trim, sold for commercial applications such as schools, healthcare and multi-tenant buildings. The Corbin Russwin 483F80 is listed as Grade 1 and is a Corridor/Dormitory function outside lever for the ML2000 Series. The difference to keep in mind is scope: the 483F80 is outside trim tied to a specific lock function, while the 09-402-KNOBS is an interior knob service kit that restores the existing L Series lock to its original function.
9) Is this Schlage knob kit suitable for a high traffic commercial building?
Yes. It is classed as a commercial replacement part for L Series trim, which is Schlage's commercial mortise line, and it is used in offices, schools, hospitals, government buildings, hotels, multi-tenant residential, and warehouses.
10) Is this a genuine Schlage part or an aftermarket knob?
Genuine Schlage. It is an authentic Schlage replacement component for L Series trim, which matters if your facility spec or an existing hardware schedule calls for factory parts.
