Hager 47KN Night Latch Lever – Grade 1 Standard Duty for 4700 Series
The Hager 47KN Night Latch Knob is a high-security, standard-duty trim designed specifically for use with Hager 4700 Series Exit Devices. This Night Latch Function (ANSI 03) trim—also known as Storeroom Function—ensures that the exterior knob is always locked and rigid. Entry is only permitted via a key, which retracts the latchbolt for immediate access. This makes the 47KN the premier choice for secure storage rooms, mechanical closets, and rear commercial entryways where unauthorized entry must be strictly prevented.
As a BHMA Certified Grade 1 component, the 47KN is built to withstand the rigorous demands of high-traffic institutional environments. The trim features a rugged steel body and a solid brass or stainless steel ball knob, providing a classic tactile feel with industrial-grade mechanical reliability. Its timeless design ensures it fits seamlessly into any architectural setting while maintaining the highest levels of perimeter security.
Secure Access & Precision Engineering
The Hager 47KN is supplied with a conventional Schlage C Keyway cylinder as standard, allowing for easy integration into existing master key systems. To provide a permanent and stable mount on 1-3/4" thick doors, this trim includes thru bolts as standard hardware. This creates a high-strength, through-the-door connection that prevents the knob assembly from loosening, wobbling, or being tampered with over time.
