N Series Pin Tumbler Deadbolt For Door Security

N Series pin tumbler deadbolt sets up a master keyed/keyed different flat black lock that ties into the Olympus N Series system on doors needing controlled access. The deadbolt lock uses a solid brass pin tumbler cylinder so the keying stays consistent with other N Series hardware on the job. The body is zinc die cast, giving the cylinder a stable housing that supports precise key operation in repeated cycles. The cylinder length is 15/16 inch, which suits door constructions that are built around this standard size. The keyway follows the N Series pattern, equivalent to National D4291 4-pin or D4292 5-pin systems, so existing N Series key systems can operate this lock. The deadbolt has a flat black finish that visually matches other flat black door components in the same opening.

Deadbolt Details That Support Key Control

• The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, lets this deadbolt operate within a broader N Series key hierarchy where a single pattern can manage multiple doors.
• Stock keying as KD/KA 4-pin standard, with stock KA numbers 101, 103, 107, and 915, sets clear key groups so multiple locks can share or separate access as required on a project.
• Master keyed operation using a 5-pin standard, with grand masterkeyed capability available, supports tiered access levels where different user groups need controlled entry through the same door.
• The rekeyable design using a set screw cylinder release mechanism allows cylinder changes based on existing N Series setups so key plans can be adjusted as occupancy or access patterns change.
• Two keys assigned per lock give an immediate working pair for each keyed position so installers and facility teams can place one key in service and retain another for controlled access.

Functional Locking And Cylinder Construction Details

The Olympus N Series pin tumbler deadbolt uses a solid brass cylinder that forms a precise interface with N Series keys so the locking action remains consistent with other brass-based cylinders. The zinc die cast body supports the cylinder in the door so the key plug stays correctly aligned over repeated use. The cylinder length of 15/16 inch sets the lock up for doors built to accept that length, which aids layout when coordinating with other N Series hardware. The standard function keeps the key removable in both locked and unlocked positions, which lets users remove the key after securing or opening the door. A non-handed standard function means the same lock body serves on either side orientation where this deadbolt is specified.

Deadbolt Use, Grade Rating, And Keying Roles

Where This Olympus N Series Deadbolt Fits Best

The N Series pin tumbler deadbolt door lock fits projects that already use, or plan to use, Olympus N Series keying because the keyway is N Series, equivalent to National D4291 4-pin or D4292 5-pin systems. The 15/16 inch cylinder length aligns with door builds that are laid out around this specific length, supporting consistent backset and edge prep where this dimension is standard. An ANSI/BHMA A156.11 Grade 1 performance rating, equivalent to E07121(100DR), positions this lock for openings that call for a Grade 1 deadbolt function. The flat black finish supports door designs that call for a dark, uniform appearance on visible lock components so hardware lines stay consistent from room to room.

Why Keying, Materials, And Function Support Workflow

Being keyed together with other N Series locks means this deadbolt can share a common key with matching N Series cylinders, which reduces the number of keys users carry when locks are set to a KA group. The stock KD/KA 4-pin standard, with KA numbers 101, 103, 107, and 915, allows different doors to be planned into keyed-alike sets or left keyed different when separate control is needed, which supports clear keying charts. Master keyed operation on a 5-pin standard, with grand masterkeyed capability available, allows a higher-level key to operate multiple locks so maintenance or management staff can operate groups of doors while individual users retain limited-access keys. The rekeyable set screw cylinder release mechanism lets existing N Series cylinders be swapped so buildings can stay on a single N Series keyway after tenant or staff changes. A standard function that keeps the key removable in both locked and unlocked positions allows users to remove the key immediately after locking or unlocking, which supports straightforward routines in day-to-day door operation.

Common Questions About This N Series Deadbolt
