• The Woodwork Institute acknowledges this product, so it aligns with WI-recognized hardware selections on projects that follow Woodwork Institute standards.

Cam Lock Mounting, Bore, And Key Function Details

This Olympus Lock, Inc. DCN4-US19-103 cam lock is built for 1-1/2 inch material thickness with a 3/4 inch bore diameter, so it matches a standard cylindrical cam lock hole pattern drilled through thicker cabinet or panel stock. The 1 inch face overlays the edge of the bore, which helps mask rough drill edges and keeps the installation looking clean without a separate trim component. Standard function allows key removal in both locked and unlocked positions, so users can remove the key after locking or leave the lock unlocked but key-free when frequent access is needed. The pin tumbler cylinder uses the N Series keyway and is rekeyable via the cylinder retainer clip, giving locksmiths and hardware specialists flexibility to adjust keying in the field within N Series systems.

How This Olympus Cam Lock Works In The Field

Flat Black N Series Lock For Cabinets And Enclosures

The Olympus DCN4 pin tumbler cam lock in flat black US19 finish gives casework and cabinet runs a dark, uniform look while still using a standard N Series keyway. The lock body and cylinder are zinc die cast, so they match common commercial cam lock construction when coordinated with other Olympus cam locks on the job. This DCN4-US19-103 configuration is keyed alike 103, allowing multiple locks keyed to KA103 to operate on the same key, which simplifies key distribution when several cabinet doors or panels should be controlled together. Stock keying is KD or KA with 4 pin standard, while masterkeyed systems use 5 pin standard and grand masterkeyed capability is available in the N Series system, so this lock can participate in tiered key control on larger projects. Keys are provided on the N Series keyway that is equivalent to National D4291 4-pin or D4292 5-pin systems, which means this cylinder profile integrates into N Series plans built around those National-style key sections.

Grade 1 Performance, Cams, And Face Coverage Benefits

This cam lock has passed ANSI/BHMA A156.11 Grade 1 performance requirements, so it is designed to meet that Grade 1 cam lock performance level where a higher test standard is specified. The lock uses two reversible cams that work in all positions, which gives hardware planners flexibility in how the cam engages strikes or frame edges at different clock positions on doors or drawers. The anti-rotation plate references in the related accessory line help keep the lock body from spinning in the bore, while the lost-motion cam shifter is designed to support more complex cam action layouts in compatible setups. The 1 inch face covers splintering around the 3/4 inch bore, which helps produce a neat, finished appearance even when the drilled hole shows minor breakout on the face side of the panel. The pin tumbler zinc die cast cylinder supports the N Series keyway, tying the cam lock into broader Olympus N Series installations where rekeyable cylinders and shared keyways reduce keying complexity over time.
