Schlage C keyway cylinder describes this Olympus Lock, Inc. solid brass lock plug designed for cabinet lock applications using the Schlage C key system. The cylinder body is solid brass, which provides a stable machining base and consistent pinning characteristics for 6-pin keying work. It is drilled for 6 pins, so it supports standard 6-pin Schlage C keying layouts where additional pin stacks are needed for key control. The cylinder is keyed different (KD), so each unit operates on its own key combination, which is useful where separate cabinets or stations require distinct keys for access control. This cylinder is listed as a lock plug in the locks and latches lock accessories category, so it serves as the pin tumbler core that finishes less-cylinder cabinet lock bodies into working keyed locks.
This Olympus Lock, Inc. cylinder is described as a vertical driver type, so it is oriented for cabinet lock bodies that use a vertical driver bar arrangement. It is made to work with Olympus less cylinder cabinet locks described as taking a Schlage standard cylinder, which means it is the active plug and driver assembly that turns inside those housings. The Schlage C keyway determines the key blank pattern that operates the pins, tying the cylinder to Schlage C cabinet key systems. Because the cylinder is drilled for 6 pins, it supports 6-pin stacks that align with the key bitting, which matters when setting up consistent locking rotation in cabinets or drawers.
This Schlage C keyway cylinder works with Olympus less cylinder cabinet locks that are designed for a Schlage standard cylinder, so it acts as the plug that completes those bodies into functioning locks. In a cabinet lock assembly, the cylinder engages the lock mechanism through its driver components, transferring key rotation to the cam or latch inside the lock body. As a lock plug product in the locks and latches lock accessories category, it occupies the critical position between the key and the cabinet hardware, turning keyed input into mechanical movement at the lock. The satin brass (US4) identification defines the face appearance, so it visually coordinates with satin brass cabinet pulls or hinges in woodworking and casework projects where finish matching matters across visible hardware.
The product description states this is a vertical driver configuration, which aligns it with cabinet lock designs that use a vertically oriented driver bar behind the cylinder, allowing the key-turn motion to drive locking parts along a vertical axis. That arrangement is useful in cabinet doors or drawers where the internal mechanism is set up for vertical driver engagement, letting this cylinder drop into those lock bodies and operate correctly. Being drilled for 6 pins means each chamber in the plug can accept up to six pin segments, which supports 6-pin Schlage C keying schemes normally used when tighter key control or longer key bitting is required. The keyed different designation (KD) establishes that each cylinder is set to a unique combination, which supports layouts where individual cabinets, office stations, or storage locations are intended to remain separate in their keying. The Olympus Lock, Inc. branding and specific part number 78-201VUS4-KD give a precise reference that ties this combination of Schlage C keyway, vertical driver style, satin brass finish, and keyed different configuration into one identifiable cylinder for repeat ordering or matching during service work.
This Olympus Lock, Inc. cylinder uses a Schlage C keyway, so it takes keys cut on the Schlage C pattern when pins are set to match that keying.
The cylinder is drilled for 6 pins, allowing 6-pin Schlage C keying layouts where longer bittings and more pin stacks are used for key control.
The keyed different (KD) designation means each cylinder is set to a unique key combination, which separates access between cabinets or lock locations.
This cylinder functions as the lock plug in Olympus less cylinder cabinet locks, turning key rotation into movement of the internal locking mechanism.
The 78-201VUS4-KD cylinder is satin brass (US4), so the exposed face shows a satin brass appearance that coordinates with similar cabinet hardware finishes.
The vertical driver description means the cylinder is intended for cabinet lock bodies using a vertically oriented driver bar, aligning rotation with those internal parts.
This Olympus Lock, Inc. 78-201VUS4-KD solid brass cylinder combines a Schlage C keyway, 6-pin drilling, vertical driver configuration, satin brass face, and keyed different setup, so it matches cabinet lock projects built around Schlage C key systems using Olympus less cylinder lock bodies.
