Sargent 10XU15 Grade 1 Passage Cylindrical Lock, Non-Keyed

The Sargent 10XU15 is the passage function in the 10X Line, built to the same structural standards as the keyed entrance and storeroom versions. It exceeds ANSI/BHMA Grade 1 requirements by as much as 20 times depending on the test, and it's been verified to 20 million operating cycles under UL testing (Verification ID: V584148).

How ANSI F75 Passage Function Works

ANSI F75 means both levers are always free. There's no cylinder, no push button, no turn button, and no locking mechanism of any kind. The latch bolt retracts when either lever is turned from either side. The door latches closed when released and opens freely from both sides at all times. The 10XU15 is the non-keyed version: it ships without a cylinder prep. No cylinder position is machined into the housing. If your project requires a passage lock that could accept a cylinder for future function change, confirm at time of order whether the XU configuration or a standard cylindrical passage with less-cylinder option better suits your long-term requirements.

Why the 10X Line Exists: Specs That Exceed Grade 1 By Up to 20x

The ANSI/BHMA A156.2 Grade 1 standard sets the commercial baseline. The 10X Line was engineered for environments where that baseline isn't enough. Here's what that means in hard numbers.

Lever torque: the 10XU15 prevents entry and maintains lever integrity against more than 3,100 in-lbs of torque applied to the locked lever. ANSI Grade 1 requires 1,200 in-lbs. That's 2.6 times the standard. On a passage door where someone forces the lever hard because they expect it to lock when it's actually just latched, the 10X structure absorbs it without failure.

Offset lever pull: the lock withstands 1,600 lbs of offset pull force while continuing to restrict entry. ANSI Grade 1 requires 200 lbs. That's 8 times the standard.

Preload: the 10XU15 ensures latch retraction with 100 lbs of preload applied to the latch bolt, simulating warped doors or latch bind conditions. ANSI Grade 1 requires 50 lbs. That's 2 times the standard.

Vertical impact: the lock prohibits entry after more than 100 vertical impacts. ANSI Grade 1 requires 5 impacts. That's 20 times the standard.

Cycle testing: 20 million successful operating cycles, independently verified by UL (Verification ID: V584148). The ANSI Grade 1 cycle requirement is 1 million.
