Accentra AU 426F Classroom/Storeroom Exit Device Trim | US32D Satin Stainless Steel
The Accentra AU 426F Classroom/Storeroom Exit Device Trim (formerly Yale) is a high-performance, heavy-duty lever trim designed for versatile security management. Engineered for high-traffic institutional and commercial environments, this Grade 1 certified escutcheon trim allows for seamless transitions between Classroom (ANSI 08) and Storeroom (ANSI 09) functions. Finished in a professional US32D (630) Satin Stainless Steel, it provides a durable and aesthetically modern solution for schools, hospitals, and office buildings.
Built with the Augusta (AU) lever style, the 426F is designed to withstand the rigors of heavy daily use. Its innovative design allows for very easy field conversion between functions: use the classroom setting to lock or unlock the lever with a key, or switch to the storeroom setting to ensure the door is always locked from the outside while allowing free egress from the inside.
Versatile Security & Industrial Durability

- Dual Functionality: Easily switch between Classroom (08) and Storeroom (09) functions in the field to adapt to your facility's changing security needs.
- ANSI/BHMA Grade 1 Certified: Rigorously tested to exceed A156.3 standards for long-term durability and reliable performance in high-frequency areas.
- Augusta (AU) Lever Design: Features a sleek, ergonomic lever that is ADA compliant and provides a comfortable grip for all users.
- Through-Bolted Security: Attaches directly to the interior exit device through the door, creating a high-strength "sandwich" mount that resists vandalism and hardware loosening.
- Field Reversible Handing: Ships as Right Hand Reverse (RHR) but is completely field reversible to accommodate any door swing requirement during installation.
- Satin Stainless Steel Finish (630): Provides maximum corrosion resistance and a clean, professional appearance that blends with modern architectural hardware.
