Introduction
The Von Duprin 996L Lever Trim is a widely used component in exit devices, particularly within the 98L and 99L series. Designed for durability and vandal resistance, this trim offers a practical solution for environments where door hardware is susceptible to damage. The 996L series includes variations suited for different applications, such as rim and mortise-prepped devices, and features a breakaway design to prevent costly repairs. This article provides a detailed overview of the 996L Lever Trim based on the technical data from official product listings, focusing on its specifications, features, and general installation considerations.
Key Features and Specifications of the 996L Lever Trim
The 996L Lever Trim is a lever-style operating component used with Von Duprin exit devices. It is commonly found in heavy-duty environments and is designed for use in both rim and mortise exit devices. Below are the key specifications and features as provided in the official documentation:

Breakaway Design
One of the standout features of the 996L Lever Trim is its breakaway design. This feature is particularly useful in areas where vandalism is a concern. The trim is engineered to separate from the door hardware under excessive force, preventing damage to the internal mechanism and reducing repair costs. It is important to note that this feature is not available in night-latch (NL) or dummy trim (DT) versions of the 996L series.
Electrified Variants
An electrified version of the 996L trim is available, designed for applications where electric control of the exit device’s latchbolt is necessary. This variant is suitable for use in stairwell conditions or where fire/life safety codes require a "fail safe" function. The electrified model requires minimal power draw, eliminating the need for a high-capacity power supply to handle surge current. This makes it an efficient solution for installations where traditional electrified latch pullback devices may be cost-prohibitive or unnecessary.
Application-Specific Models
The 996L Lever Trim is available in versions tailored for different door hardware configurations:
- Rim Devices (996L-R/V-06): Designed for rim-prepped exit devices. Requires a 1-1/8 inch rim cylinder.
- Mortise Devices (996L-M-06): Designed for mortise-prepped exit devices. Requires a 1-1/4 inch mortise cylinder.
- Motorized Breakaway Version (M996L-R/V-06): A motorized variant that retains the breakaway feature while enabling remote control or automated operation.
Each of these models is built to meet the specific needs of its intended use case, ensuring compatibility with the 98L and 99L series exit devices.
Installation Considerations
While the provided source material does not include detailed step-by-step installation instructions, general guidance can be inferred from the product specifications and intended applications.
Compatibility and Preparation
Before installing the 996L Lever Trim, it is essential to verify compatibility with the existing door hardware. The trim is designed to work with the 98L and 99L series exit devices, which are commonly used in commercial and institutional settings. The following factors should be considered:
- Door Type: The 996L Lever Trim is suitable for both rim and mortise-prepped doors. Ensure the door hardware is properly prepared for the trim’s mounting requirements.
- Cylinder Size: For rim applications, a 1-1/8 inch rim cylinder must be ordered separately. For mortise-prepped devices, a 1-1/4 inch mortise cylinder is required.
- Handing: The trim is available in left-hand reversed (LHR) configuration. Confirm that the trim’s handedness matches the door’s orientation to ensure correct operation.
- Finish Selection: Choose a finish that matches the aesthetic and corrosion resistance requirements of the installation environment. Satin Brass is a common choice, but other finishes may be available.
Mounting and Adjustment
The installation process involves securing the trim to the door using the provided hardware and adjusting the lever and escutcheon plate to ensure smooth operation. While specific torque values and adjustment procedures are not detailed in the source material, it is recommended to follow standard mechanical installation practices for lever trims.
- Lever Alignment: The lever should be aligned with the door’s edge to ensure even pressure and prevent binding.
- Escutcheon Plate Fit: The escutcheon plate should be securely attached and properly aligned with the door frame to provide a finished appearance and protect the door edge from damage.
- Breakaway Mechanism: The breakaway feature should be tested after installation to ensure it functions correctly under normal use and in the event of excessive force.
Electrified Models
For electrified models, additional wiring and control components may be required. These models are typically used in applications where the exit device needs to be controlled remotely or in response to specific events, such as fire alarms or security system triggers. When installing an electrified 996L Lever Trim, it is important to:
- Verify Electrical Requirements: Confirm the voltage and current requirements of the device to ensure compatibility with the existing power supply.
- Follow Electrical Codes: Adhere to local electrical codes and safety regulations when connecting the device to the control system.
- Test Functionality: After installation, test the device to ensure that the electrified functions operate as intended and that the breakaway mechanism is not compromised by the electrical components.
Maintenance and Troubleshooting
Although the source material does not provide detailed maintenance instructions, general best practices for maintaining lever trims include regular inspection for signs of wear or damage and lubrication of moving parts to ensure smooth operation. In environments where vandalism is a concern, the breakaway design of the 996L Lever Trim can reduce the need for frequent repairs by preventing internal damage to the exit device.
If the trim is found to be malfunctioning or not operating as expected, the following steps may be useful in troubleshooting:
- Check for Physical Damage: Inspect the lever, escutcheon plate, and internal components for signs of impact or wear.
- Test Breakaway Function: Apply moderate force to the lever to ensure the breakaway feature engages and disengages as expected.
- Verify Electrical Connections (if applicable): For electrified models, check for loose or damaged wiring and ensure that the control system is functioning correctly.
- Consult Manufacturer Documentation: If the issue persists, refer to the manufacturer’s technical support resources or contact Von Duprin for assistance.
