Accentra AU 448F Passage Function Exit Device Trim | Grade 1
The Accentra AU 448F Passage Function Exit Device Trim (formerly Yale) is a premium, high-traffic architectural solution designed for commercial openings where keyed security is not required. This Passage (ANSI 14) function features a lever that is always unlocked, allowing for free entry at all times while providing a durable, ergonomic grip for building occupants. It is the premier choice for internal office doors, shared supply rooms, and non-secured corridors in schools, hospitals, and industrial facilities.
As an ANSI/BHMA Grade 1 certified component, the 448F is engineered to withstand millions of cycles under heavy daily use. The Augusta (AU) lever style offers a clean, professional aesthetic that is fully ADA compliant. Designed specifically for convenience, the 440F Rose Trim fits seamlessly into standard 161 Prep (2-1/8" bore) door holes, making it an ideal choice for quick retrofits and new installations alike.
Superior Durability & Effortless Access
- Always-Unlocked Passage Function: Perfect for high-frequency transition areas where immediate access is required without the need for keys or locking mechanisms.
- Industrial Grade 1 Strength: Tested to exceed A156.3 standards, ensuring top-tier mechanical durability and long-term reliability in demanding institutional environments.
- Streamlined 161 Prep Retrofit: The 440F Rose design is optimized for doors with a standard 2-1/8" bore, allowing for a clean installation on stock doors without extensive modifications.
- Heavy-Duty Through-Bolted Mount: Attaches directly to the interior exit device through the door for a secure "sandwich" installation that prevents the trim from loosening or sagging over time.
- Ergonomic Augusta (AU) Lever: Provides a comfortable, easy-to-operate handle that meets all federal accessibility requirements for public buildings.
- High-Quality Architectural Finishes: Available in Satin Chrome (626), Dark Bronze (695), and Black Suede Powder (BSP) to match your existing hardware and décor.
