Sargent LC-8904-F-ETL Mortise Exit Device, Night Latch, For 33-36" Dr Widths, Less Cylinder

The Sargent LC-8904-F-ETL is a heavy-duty mortise exit device built for high-traffic commercial openings that demand reliable fire-rated performance. Configured for night latch function with the ET lever trim, it provides secure keyed entry from the exterior while allowing free egress from the inside. This model is sized for door widths of 33" to 36" and ships less cylinder, giving installers the flexibility to specify their preferred mortise cylinder. As part of Sargent's respected 80 Series, it combines rugged mortise lock construction with the dependability expected in institutional, educational, and healthcare settings where life-safety compliance is essential.

Features

• Mortise exit device with night latch function for keyed entry from the outside and free egress inside.
• Fire-rated (F) construction suitable for labeled door and frame assemblies.
• ET lever trim (ETL) for comfortable, ADA-friendly operation on the exterior.
• Sized for doors measuring 33" to 36" in width.
• Supplied less cylinder, allowing use of a preferred mortise cylinder.
• Durable 80 Series mortise lock body engineered for high-use commercial applications.

Functional Details

The night latch (04) function provides a latchbolt that is retracted by a key from the outside and by the touchpad from the inside. The exterior trim is a pull with cylinder only, so there is no outside operating lever to grant free access unless keyed.

• Night Latch: Exit only, key retracts latch.

Arm Type Details

The ET trim designation refers to Sargent's ET lever trim design, which pairs with the mortise exit device to allow the latch to be retracted from the exterior via key operation while maintaining a clean, contemporary lever profile.

Included Components

This configuration includes the 8904 mortise exit device chassis, F fire-rated mortise lock body, and ETL lever trim. A mortise cylinder is not included and must be ordered separately.
