Sargent 6U65 OB Privacy Knob Lockset
Function Information:
The Sargent 6U65 OB is a professional-grade Grade 2 Cylindrical Privacy Knob Latchset designed for dependable performance in commercial and institutional interior openings. As a core offering within the reliable Sargent 6-Line Series, this hardware is engineered for spaces where personal privacy is essential but keyed security is not required. Featuring the classic OB Ball Knob design, this latchset provides a timeless, comfortable grip combined with a heavy-duty chassis built to outperform standard residential-grade hardware.
Durable Engineering and Privacy Control
The 65 Privacy Function (ANSI F76) is the industry standard for single-occupant rooms such as restrooms, dressing rooms, and private offices. The Sargent 6-Line chassis is constructed from high-strength steel and zinc dichromate plating to resist internal corrosion, ensuring the mechanism remains fluid through years of high-frequency use.
- Interior Push-Button Locking: The exterior knob is quickly locked by pressing the button on the interior rose. This provides the occupant with immediate privacy and visual confirmation that the door is secured.
- Automatic Reset Logic: Rotating the interior knob or closing the door automatically releases the push-button. This "anti-lockout" feature is critical for facility managers, as it prevents rooms from being left locked when unoccupied.
- Emergency Access Override: For life-safety compliance, the exterior knob features an emergency release slot. Authorized personnel can easily unlock the door from the corridor side using a simple tool if an occupant requires assistance.
- Timeless OB Knob Aesthetic: The OB Ball Knob is a versatile architectural choice, providing a clean, professional look that fits seamlessly into office suites, healthcare clinics, and educational facilities.
