Olympus DCN4 pin tumbler cam lock gives a keyed cylinder solution for applications needing a 1-1/2 inch material thickness with a 3/4 inch bore diameter, so it suits installations built around that specific panel thickness and hole size. The flat black finish identified by US19 provides a dark, low-visibility face, which helps this lock blend with flat black hardware runs and darker surfaces. The zinc die cast body and pin tumbler cylinder construction provide a metal housing and locking core, which supports a solid feel when the key operates the lock. N Series keyway compatibility allows this lock to be keyed together with other N Series locks, so a single key can operate multiple lock points when they share that system. The standard function keeps the key removable in both locked and unlocked positions, which allows the key to be taken away without changing the cam position.
The stated 1-1/2 inch material thickness with 3/4 inch bore diameter focuses this Olympus DCN4 pin tumbler cam lock on panels sized to that thickness and hole, which guides drilling and boring steps in the shop. The 1 inch face dimension covers the surrounding bore area, so slight chipping at the edge of the drilled 3/4 inch hole stays hidden behind the lock face. The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, lets the lock fit into keying plans already based on that series. Stock keying using KD/KA in a 4 pin standard format, and stock KA numbers 101, 103, 107, and 915, frame how groups of locks can be coordinated in a keyed different or keyed alike pattern.
This Olympus DCN4-US19-KD cam lock belongs to the cam locks class under locks and latches, placing it in typical cabinet and enclosure lock applications that accept a cam-style latch. The zinc die cast body paired with a zinc die cast pin tumbler cylinder places a metal housing and core in the panel, giving a familiar feel for installers working with this lock type. The flat black finish lets it sit visually with other flat black components, which suits projects that follow that finish schedule. As a WI acknowledged product, it aligns with Woodwork Institute references, which matters when projects prefer using parts that appear in that acknowledgment list.
The standard function keeps the key removable in both locked and unlocked positions, which simplifies workflows where the installer or user needs to pull the key regardless of cam position. Two reversible cams that work in all positions provide flexibility when deciding whether the cam needs to throw up, down, left, or right, which helps the same lock part number serve multiple door or panel layouts. The N Series keyway lets this lock be keyed together with other N Series locks, which simplifies key management when several cam locks and related locks rely on one coordinated key system. Rekeyable construction via a cylinder retainer clip gives the option to change cylinders to new keys, which supports future rekeying without replacing the main lock body in the material. Stock masterkeying in a 5 pin standard format and the availability of grand masterkeyed setups allow this product to participate in tiered key systems, which helps when multiple access levels are planned across a project.
The Olympus DCN4 pin tumbler cam lock is specified for 1-1/2 inch material thickness with a 3/4 inch bore diameter, which directs panel thickness and boring operations.
The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, allows this lock to be keyed together with other N Series locks for coordinated keying.
The cam lock has passed ANSI/BHMA A156.11 Grade 1 performance requirements, tying it to a defined cam lock performance standard within that specification.
The Olympus DCN4 standard function allows the key to be removable in both locked and unlocked positions, which lets the key be withdrawn without changing cam status.
The two reversible cams operate in all positions, giving flexibility to set the cam throw direction for different door or panel layouts using the same lock.
The 1 inch face covers splintering around the 3/4 inch bore, eliminating the need for an added trim ring and helping hide minor edge damage at the drilled hole.
This Olympus DCN4-US19-KD flat black pin tumbler cam lock combines a zinc die cast body, N Series keyway, and 1 inch face sized for a 3/4 inch bore in 1-1/2 inch material, aligning with projects needing that specific geometry and keying system. For work that already specifies N Series keying, this cam lock supports keyed different, keyed alike, and masterkeyed configurations within that framework. When a flat black, ANSI/BHMA A156.11 Grade 1 cam lock with reversible cams fits your planned material thickness and bore size, this Olympus DCN4 configuration is ready for those layouts.
