Sargent 10XG05 LL Grade 1 Office Lever Cylindrical Lockset

The Sargent 10XG05 LL is a Grade 1 commercial cylindrical lockset configured for the Office / Entry function — one of the most widely specified functions in commercial construction and facility management. Designed for interior office doors and secured entry points, this lever-trim lockset delivers heavy-duty performance with the reliability that Sargent's 10 Line series is known for.

Office / Entry Function — What It Does

The Office (Entry) function on a cylindrical lockset operates as follows: the outside lever is normally locked and can be unlocked by a key from outside or by a thumb turn from inside — allowing controlled access while permitting free egress at all times from the interior. The inside lever always retracts the latch. This function is ideal for private offices, executive suites, administrative areas, and similar secured interior openings where staff need key-controlled access from the corridor but unrestricted exit from within.

• Outside lever locked by default; key from outside or thumb turn from inside controls access
• Inside lever always free — no key required to exit
• Auxiliary deadlatch standard for added security against latch shimming
• Suitable for ADA-compliant accessible hardware specifications (lever handle)

Key Benefits

• ANSI/BHMA Grade 1 — heaviest-duty commercial classification; engineered for high-cycle, high-traffic openings
• Lever trim (LL lever style) — ADA-accessible lever handle design meets accessibility requirements on compliant openings
• Cylindrical (bored) lockset — installs in standard 2-1/8" bore; compatible with common door preparations
• Sargent 10 Line platform — field-proven series with broad cylinder and keying system compatibility including Sargent V-10 ASSA interchangeable core prep options
• Commercial-grade construction — built for office buildings, healthcare facilities, educational environments, and institutional applications

Typical Applications

• Private offices and executive suites
• Administrative and staff corridors
• Healthcare clinic and hospital office doors
• Educational facility office and administrative entries
• Government and institutional interior secured doors
• Any commercial opening requiring key-controlled exterior access with free interior egress

The Sargent 28-10XG05 LL is a premier Grade 1 Cylindrical Lock engineered to provide versatile security for professional environments. As a flagship model in the Sargent 10X Line, this lockset is designed for high-traffic "Office or Entrance" applications (F109 function). It features an innovative push/turn button on the interior lever, allowing users to toggle between a locked and unlocked exterior handle. Built to withstand extreme physical abuse, the 10X line exceeds ANSI/BHMA standards by up to 20 times, ensuring your facility remains secure for decades.

Versatile "Office or Entrance" Functionality

The 10XG05 offers the flexibility needed for modern workplaces. When the interior button is pushed, the outside lever is locked until released by a key from the outside or by turning the inside lever. If the button is turned, the outside lever remains locked even after egress, requiring a manual release. This deadlocking latch design ensures that the door cannot be "shimmied" open, while the freewheeling lever option protects the internal chassis from vandals attempting to force the handle.

Engineered for Extreme Durability

The Sargent 10XG05 is built to survive the toughest conditions. It has been tested to 20 million cycles, far surpassing the requirements for ANSI/BHMA A156.2 Grade 1 certification. With the ability to withstand 3,100 in-lb of abusive torque and 1,600 lbs of offset pull, this lockset is nearly impenetrable to standard vandalism. Its independent return springs ensure the LL lever stays horizontal without sagging, maintaining the architectural integrity of your building.
