Schlage 09-633N 626 KN L583-363 – Frequently Asked Questions

1) What exactly does the Schlage 09-633N KN L583-363 include, and is it the whole lock?
It's interior trim only, not a complete lock. The 09-633N KN L583-363 is a thumbturn by knob N escutcheon assembly for Schlage L Series mortise locks, with a large ADA thumbturn for locking and unlocking from the inside. The mortise lock case, cylinder and exterior trim are separate. Order it when you are replacing or upgrading the inside escutcheon on an existing L Series installation.
2) Will this thumbturn escutcheon fit a Schlage L Series mortise lock I already have in the door?
Yes, it is built specifically for Schlage L Series mortise lock interior trim, so it matches the L Series escutcheon prep and function on an existing installation. It is not trim for cylindrical locks or for other manufacturers' mortise cases.
3) Is the large thumbturn on this Schlage escutcheon ADA compliant for a restroom or patient room?
The oversized thumbturn is an ADA-compliant design, meaning it can be operated without tight grasping, pinching or wrist twisting. That is what makes it the choice for single-occupant restrooms, exam rooms and other openings where the interior lock has to be usable with a closed fist.
4) What finishes does the Schlage 09-633N thumbturn escutcheon come in so I can match the other doors?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. Match the BHMA number stamped on your existing L Series trim rather than the finish name, since 626 satin chrome and 630 satin stainless look similar but are not the same.
5) What model number do I give my supplier for this Schlage ADA thumbturn escutcheon?
The model is 09-633N KN L583-363, the thumbturn by knob N escutcheon with the large ADA thumbturn for L Series interiors. Specify the finish number along with it, since that is the only ordering choice on it.
6) If the opening needs coded entry rather than a thumbturn, what is the closest Schlage option?
The 09-633N KN L583-363 provides mechanical interior locking through a large ADA thumbturn and has no credential reader. Where coded entry is required on a cylindrical or mortise lock, the Schlage Electronics 47260707 CO Series exterior escutcheon is the keypad equivalent housing and ships with fasteners and an O-ring; for exit device applications the Schlage Electronics 47260708 CO-100 keypad escutcheon is the exit trim version. Both are exterior escutcheons, so an interior thumbturn trim would still be specified separately if the function calls for one.
7) I need an escutcheon for exit device trim, not a mortise knob - what should I look at instead?
The 09-633N KN L583-363 is built for Schlage L Series mortise lock interior trim and will not serve exit device trim. For an exit trim application, the Schlage Electronics 47260708 is a CO-100 Series exterior escutcheon made specifically for exit trim, with a keypad, in aged bronze finish. Note that it is a keypad credential unit rather than a mechanical thumbturn escutcheon, so the opening has to be one where electronic access control is wanted.
8) Is the MS Sedco ESC escutcheon plate an alternative if I just need a stainless plate?
They cover different jobs. The MS Sedco ESC is a decorative stainless escutcheon plate for R4 and R6 round switches, part of the switches line - it trims an actuator or switch, not a lock. The Schlage 09-633N KN L583-363 is a commercial replacement escutcheon that carries a knob and a large ADA thumbturn for an L Series mortise lock, and is offered in eight finishes including 629 bright stainless steel and 630 satin stainless steel. If the requirement is lock trim, the Sedco plate will not mount to the mortise case.
9) Is this escutcheon rated for commercial traffic or is it a residential part?
Commercial. It is built to Schlage's commercial hardware standards and is used in offices, schools, healthcare, government buildings, retail, multi-tenant residential and industrial facilities.
10) Is this a genuine Schlage part or an aftermarket copy?
Genuine Schlage. It's an authentic Schlage parts and accessories component, so fit, finish and operation match the original L Series trim you are working with.
