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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eGrade 2 cylindrical lock construction for commercial and light commercial use\u003c\/li\u003e\n \u003cli\u003ePassage function: non-keyed, free egress from both sides at all times\u003c\/li\u003e\n \u003cli\u003eSpringlatch mechanism for positive door latching without deadbolt\u003c\/li\u003e\n \u003cli\u003eNon-handed design installs on left-hand or right-hand doors without adjustment\u003c\/li\u003e\n \u003cli\u003eB-style knob with O-style rose for a classic, low-profile appearance\u003c\/li\u003e\n \u003cli\u003eBright brass (03) finish for traditional architectural compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Grade 2 cylindrical passage lock for standard commercial cylindrical door prep applications.
