Olympus DCN4 Pin Tumbler Cam Lock, 1-1/2" Material Thickness with 3/4" Bore Diameter, Keyed Alike 107, Bright Brass

Olympus DCN4 Pin Tumbler Cam Lock Use

Olympus DCN4 pin tumbler cam lock provides a cam lock solution built around a zinc die cast body and a zinc die cast pin tumbler cylinder, which creates a compact locking unit that suits woodworking and casework applications needing a cam-operated lock. The 1-1/2 inch material thickness rating with 3/4 inch bore diameter supports installations in panels sized for that bore, so casework prepared to that spec can accept this lock without extra fitting passes. A 1 inch face that covers splintering around the bore helps conceal minor breakout at the hole edge, which keeps finished surfaces presentable after drilling. Bright brass finish, identified by the US3 designation, delivers a brass appearance that matches jobs calling for a brass-tone lock face on visible cabinet or fixture fronts. Key removable in both locked and unlocked positions defines how the key behaves at the cylinder, which shapes how the lock is used during access routines.

Key Cam Lock Details That Support Jobs

• Can be keyed together with other N Series locks, which allows multiple lock points in the same project to operate from the same key pattern when the N Series keying system is used.
• Easily rekeyable via cylinder retainer clip, so the locking combination can be changed on the same installed housing by swapping cylinders held by that clip.
• Passed ANSI/BHMA A156.11 Grade 1 performance requirements, giving the lock a tested performance classification that aligns with Grade 1 expectations for cam lock duty.
• Standard function with key removable in locked or unlocked position, letting the key be withdrawn after locking or after unlocking depending on how the opening is managed.
• Two reversible cams work in all positions, creating flexibility in how the cam is oriented to engage strikes or keeper hardware positioned for different rotation directions.
• Keying system uses N Series keyway equivalent to National D4291 4-pin or D4292 5-pin, which ties the cylinder design to a recognizable pin system for key control planning.

Cam Lock Fit, Bore Size, And Face Coverage

This DCN4-US3-107 cam lock is specified for 1-1/2 inch material thickness with a 3/4 inch bore diameter, so panels bored to 3/4 inch can accept the lock where the material stack reaches that thickness value. The 1 inch face dimension is larger than the 3/4 inch bore, which lets the round face overlap the edge of the hole so splintering at the bore perimeter is covered. The face construction eliminates the need for an additional trim ring, which keeps the installation profile to the main cylinder and face while still masking the drilled edge. Body and cylinder both use zinc die cast construction, giving a uniform metal body around the bore area that interacts consistently with the panel cut.

How This Keyed Alike 107 Cam Lock Works

Where Olympus Bright Brass Cam Lock Is Used

The Olympus bright brass cam lock with manufacturer part DCN4-US3-107 is a keyed alike 107 configuration within the N Series system, so locks carrying that KA107 pattern share a common key change in that series. Stock keying is KD or KA in a 4 pin standard format, which defines how the cylinder is pinned in its regular stock condition. The lock body and pin tumbler cylinder are both zinc die cast, giving a matched housing and core that present a consistent bright brass face identified by finish code 3. The keyway is N Series, equivalent to National D4291 4-pin or D4292 5-pin systems, so the cylinder geometry is aligned to those recognized systems. The cylinder is rekeyable via a cylinder retainer clip, which lets installers use the same housing while altering the keying to different N Series combinations as projects change. Stock keyed alike numbers 101, 103, 107, and 915 describe other available keyed alike groups in the same family, helping organize groups of locks around specific code numbers.

Why These Cam And Keying Details Matter

The standard function of this cam lock keeps the key removable in both locked and unlocked positions, which means users can lock a door, withdraw the key, and later unlock it and again remove the key without it being trapped in either state. Two reversible cams work in all positions, creating options for positioning the cam to engage on either side of the cylinder and for rotation in different directions, so the same lock type serves multiple door or panel swing layouts. The product has passed ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07261 or E07271, assigning it a Grade 1 cam lock performance rating that aligns with demanding cam lock service conditions. The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin, connects the cylinder design to an established pin system, which supports layout where N Series key control is already in use. Woodwork Institute acknowledgement identifies the product as recognized within that body, linking it to specifications where Woodwork Institute acknowledged hardware is referenced for projects.
