It features the Withnell lever style paired with a rose trim and is finished in matte black. As a passage function lock, it allows free movement through a door without requiring a key or thumbturn  -  the lever operates the latch from both sides at all times. This hardware suits commercial and light commercial interiors where traffic flow matters more than access control. Installation is handled by locksmiths, finish carpenters, or general contractors working on interior door hardware.\u003c\/p\u003e\u003cp\u003eThe 3510 BLK WTN is suited for interior passage doors in office corridors, commercial suites, hospitality spaces, and light commercial facilities where Grade 2 cylindrical locksets are specified. The matte black finish coordinates with contemporary hardware programs. Because this is a passage function, it is not appropriate for rooms requiring any level of privacy or security lockout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 2 cylindrical lock construction for commercial and light commercial duty\u003c\/li\u003e\n\u003cli\u003ePassage function  -  non-keyed, latch retracts freely from both sides\u003c\/li\u003e\n\u003cli\u003eWithnell lever design with matching rose trim\u003c\/li\u003e\n\u003cli\u003eMatte black finish for contemporary interior aesthetics\u003c\/li\u003e\n\u003cli\u003eCylindrical installation format fits standard door prep\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation cylindrical passage lockset for standard commercial interior doors with a cylindrical bore prep.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed locksmith or qualified finish carpenter. Verify door thickness and backset measurement before installation to confirm compatibility with the lock chassis. Ensure the door bore and latch bore match the required cylindrical prep dimensions.
