- Schlage S00033868141-KIT ND12/80EU CHASSIS KIT, UNASSEMBLED
The Schlage S00033868141-KIT is the OEM unassembled chassis kit for the ND12/80EU electrified cylindrical lock series. It's the mechanical core of the lock, the zinc and steel assembly that houses the motor, controls EL/EU mode selection, and connects lever operation to your access control system's power signal. When a chassis wears out, gets damaged, or fails an inspection, replacing just this kit costs a fraction of swapping the entire lock assembly. That's exactly what this part is for.

The kit ships unassembled and contains no finished parts. That's noted clearly so service techs order the right item. It's designed for professional field installation by locksmiths, facilities managers, and commercial door hardware contractors who are already working within the ND Series ecosystem.

Which Schlage ND Models Does the S00033868141-KIT Fit?

This chassis kit is a direct match for three electrified Schlage ND Series functions. The ND80EU Storeroom lock keeps the outside lever continuously locked until it's released by key or electric current, with the inside lever always free for egress. It's fail secure, meaning a power loss leaves the door locked. The ND12EL is the exit lock function with the outside lever electrically locked and fail safe operation, while the ND12EU is the exit lock counterpart configured for electrically unlocked fail secure operation.

All three share the same ANSI 161 cylindrical door preparation, which is why a single chassis kit covers the full group. If you know your model, this is the part to order.

How the ND12/80EU Chassis Works in a Wired Access Control System

The Schlage ND Series electrified chassis uses a motor instead of a solenoid. That design choice matters in practice. The peak current draw is just 0.24 amps (240mA) at 70°F, with a holding current of only 0.01 amps (10mA). At that draw, you can run more locks from a single power supply, and you won't get heat buildup in the lever, a common failure point in solenoid-based hardware that gets triggered repeatedly throughout a shift.

The chassis auto-detects 12V or 24V DC input without any manual configuration. EL and EU mode is selectable via a switch directly on the chassis, so a single stock unit covers fail safe and fail secure applications. There's no need to order separate parts for each mode. A modular Request to Exit (RX) function can also be added at any time without replacing the chassis.

The auxiliary latch deadlocks the latchbolt when the door is fully closed on all three compatible functions, which prevents the door from being shimmed open with a card or tool.

Schlage ND80EU Chassis Kit Specifications

The chassis components are zinc and steel, plated for corrosion resistance. Door thickness range is 1-5/8 inches to 2-1/8 inches (41mm to 54mm) as standard, with optional configurations from 1-3/8 inches up to 6 inches available using EE, EI, EO, or ED door position specs. The chassis is non-handed and works on both right-hand and left-hand doors with no modification.

The full ND Series has been tested to withstand 3,100 in-lb. of abusive lever torque, more than 2.5 times the ANSI Grade 1 requirement, and offset lever pull resistance up to 1,600 lbs. The ND Series is UL/cUL listed for 3-hour fire doors on single and pair configurations, and meets ADA and Buy American Act requirements.

What to Order Alongside This Chassis Kit

Because this kit ships unassembled with no finished parts, you'll want to confirm you have the correct levers, roses, and latch hardware in hand before scheduling installation. SecurityParts stocks the full range of compatible Schlage ND Series levers in nine designs across 10 finishes, including satin chrome (626), bright brass (605), and oil-rubbed bronze (613). Nine available finishes come with an optional antimicrobial coating on the 626 finish. The patented Everest 29 S123 keyway ships standard. If your facility runs a master key system with Primus XP cylinders, those are available through the Schlage catalog as well.
