Sargent 6U65 OB Privacy Knob Latchset — 6 Series Commercial Knob Lock, US26D Satin Chrome

The Sargent 6U65 OB is a commercial-grade privacy knob latchset from Sargent's trusted 6 Series cylindrical lockset line. Finished in US26D Satin Chrome (626), this unit delivers a clean, professional appearance suited to interior doors in healthcare, education, hospitality, and office environments. The privacy function allows occupants to secure a room from the inside — ideal for restrooms, changing rooms, single-occupancy offices, and similar spaces — while permitting emergency access from the outside with a release tool.

Privacy Function — What It Means for Your Application

A privacy latchset (sometimes listed as a privacy lock or privacy knob lock) is designed so the inside knob or button locks the latch from the outside without a key. Outside access is restricted but can be overridden in an emergency using a small coin or release tool through the outside knob hole. This function is not intended for security applications — it is designed for privacy and convenience, making it a standard specification for restroom doors, locker room entrances, hotel bathroom doors, and similar interior openings.

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.
