Sargent 28-7U15 LL Passage Function Cylindrical Latchset
Function Information:
The Sargent 28-7U15 LL is a professional-grade Grade 2 Cylindrical Passage Latchset engineered for high-traffic interior and exterior openings where locking is not required. As a standout in the Sargent 7-Line Series, this hardware provides an exceptional balance of mechanical reliability, modern architectural styling, and rapid installation. The 28-prefix ensures this unit is supplied with a 4-7/8" ASA Strike, the industry standard for commercial hollow metal frames. Featuring the contemporary LL Lever design, this latchset is built to surpass industry standards for both performance and longevity.
Engineered for Institutional Durability
The Sargent 7-Line is designed to outperform the baseline requirements for Grade 2 hardware, offering facility managers a "heavy-duty" feel in a versatile, standard-duty footprint:
- Superior Cycle Performance: This latchset significantly exceeds ANSI/BHMA A156.2 Grade 2 cycle requirements, ensuring years of maintenance-free service in busy commercial corridors.
- Rapid Installation: Engineered for maximum efficiency, the 7U15 can be installed in one minute or less, drastically reducing labor costs for large-scale facility retrofits.
- Structural Stability: Internal through-bolts supply unmatched strength and stability without requiring additional door preparation or complex drilling.
- 5-Year Limited Warranty: Sargent stands behind the 7-Line with a 5-year warranty that requires no maintenance or service to remain valid.
Versatile Passage Function (ANSI F75)
The 15 Passage Function is the premier choice for openings that require a secure latching mechanism without a locking feature, ensuring constant access and safety.
- Always Active Access: Both the interior and exterior levers are always unlocked and always retract the latchbolt, providing unrestricted movement between high-traffic spaces.
- ADA Compliant LL Lever: The linear, ergonomic LL design is crafted for ease of use, meeting all Americans with Disabilities Act requirements for operation without tight grasping or twisting.
- Solid Construction: Levers are solid, one-piece cast construction, providing a precise, high-quality feel that far exceeds residential-grade hardware.
- Universal Handing: The non-handed design allows for easy field installation on both left-hand and right-hand swinging doors, simplifying inventory management.
