Hager 3840S Privacy Mortise Latchset – Grade 1 Sectional Trim
The Hager 3840S Privacy Mortise Latchset is a heavy-duty commercial hardware solution specifically engineered for areas requiring private access, such as restrooms, dressing rooms, and private offices. This Privacy Function (ANSI F22) set features an internal thumbturn that locks the exterior lever, while the outside rose includes an emergency release for authorized access when needed. By utilizing the Sectional (S) Trim, the 3840S offers a contemporary, low-profile look that is ideal for high-end architectural projects where aesthetics are as important as performance.
As a BHMA Certified Grade 1 device, the 3840S is built to the highest mechanical standards. The sectional rose design provides a clean, minimalist appearance, while the internal mortise lock body is constructed from high-strength steel with a corrosion-resistant coating. This ensures smooth, reliable operation for millions of cycles in high-traffic commercial environments.
Modern Aesthetics & High-Strength Mounting
The Hager 3840S combines the industrial strength of a mortise lock with the accessibility of an ADA compliant lever handle and thumbturn. The internal components are precision-engineered to provide a solid tactile feel and prevent handle sagging over time. For a permanent and stable mount, the sectional trim is secured using thru bolts, providing a high-strength, through-the-door connection that keeps the hardware perfectly aligned even under heavy daily use.

Professional Installation Note
