Sargent 28-6U15 Ob 03 Grade 2 Passage Cylindrical Lock

Product Description

The SARGENT 28-6U15 OB 03 is a Grade 2 passage cylindrical lock designed for interior doors in commercial and light commercial applications. It features a B-style knob mounted on an O-style rose and operates with a springlatch mechanism that requires no key to operate from either side. The non-handed design simplifies installation, allowing use on left-hand or right-hand doors without modification. The bright brass finish provides a traditional appearance suitable for office, institutional, and multi-unit residential environments. Licensed locksmiths and commercial door hardware installers are the typical trade for this hardware.

This passage lock is intended for interior doors where free passage is required from both sides, such as hallways, common areas, storage rooms, and conference rooms. It does not provide locking security and is not appropriate for entry or egress doors requiring controlled access. The non-keyed, always-unlatched-on-turn function makes it suitable for high-traffic interior openings where access restriction is not required.

Installation Notes

Installation is typically performed by a licensed locksmith or commercial door hardware professional familiar with cylindrical lock door prep requirements. Verify the door bore diameter and latch backset match the lock specifications before installation. Ensure the door is not under load and is properly shimmed during installation to achieve correct latch alignment. Consult local building codes for egress and accessibility requirements that may apply to passage hardware in commercial occupancies.
