N Series Pin Tumbler Deadbolt For Door Security

N Series pin tumbler deadbolt describes a deadbolt door lock built around the N Series keyway, so it ties directly into existing N Series key systems on woodworking and commercial jobs. The solid brass pin tumbler cylinder provides a familiar, serviceable core, which supports predictable key control and consistent operation for installers who already work with National D4291 4-pin or D4292 5-pin systems. The zinc die cast body gives the lock a rigid housing, so the cylinder stays aligned in the door prep under daily use. A satin chrome finish identifies this 100-26D138-KDMK model visually as the 26D option, helping crews match hardware across a project. The lock is master keyed as a 5 pin standard, so facility-level control can be set up while still allowing individual keying where needed.

Deadbolt Features That Support Key Control Workflows

• The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, lets this deadbolt be keyed together with other N Series locks, so one key system can span multiple lock points across a project.
• The easily rekeyable set screw cylinder release mechanism allows the cylinder to be changed in the field, helping installers adjust keying without replacing the entire deadbolt assembly.
• The cylinder length options of 15/16 inch, 1-3/8 inch, or 1-5/8 inch and the 7/8 inch barrel diameter give clear dimensional targets, so door preps can be matched to the correct cylinder size for a clean fit.
• Passing ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), shows this deadbolt is tested for a high level of duty, which matters on heavily used doors in commercial or shop environments.
• The standard function with key removable in the locked or unlocked position, and an alternate function with removal in the locked position only via direct ship, lets specifiers select how the key behaves to fit site security procedures.

Installation, Cylinder Sizes, And Deadbolt Function

This Olympus Lock, Inc. N Series pin tumbler deadbolt uses a 7/8 inch barrel diameter, giving installers a precise bore size to work to when preparing doors. With cylinder lengths of 15/16 inch, 1-3/8 inch, or 1-5/8 inch available, the same core locking platform can address different door thicknesses or hardware stackups, keeping the keying consistent while matching the door build. The rekeyable cylinder release set screw mechanism means the cylinder can be released and replaced as keying plans change, which keeps rekey work to a cylinder swap instead of a full lock replacement. The standard function design, with the key removable in either the locked or unlocked position, supports flexible operating procedures, while the alternative locked-position-only option available via direct ship addresses jobs that call for tighter key handling.

Using This Olympus Deadbolt In Real Projects

Where This N Series Deadbolt Is Typically Applied

This deadbolt door lock sits in the Deadbolt Locks class and category, positioning it for door applications where a dedicated bolt is required rather than a latch-based solution. Because it can be keyed together with other N Series locks, it fits projects where a single N Series keyway is already established across cabinets, doors, or other lock points, keeping the key platform unified. The master keyed 5 pin standard configuration supports tiered access in commercial or institutional settings, so one master key can operate multiple locks while individual keys remain limited. Its ANSI/BHMA A156.11 Grade 1 performance standing, equivalent to E07121(100DR), backs its use on doors that see repeated operation in busy environments such as shops or shared work areas. The satin chrome finish aligns with common architectural hardware selections, smoothing coordination with hinges and other visible components.

Why These Deadbolt Details Matter For Repeatable Results

The N Series keyway detail matters because it aligns with National D4291 4-pin or D4292 5-pin systems, so locksmiths and installers can leverage familiar pinning practices and key blanks for efficient service. The solid brass pin tumbler cylinder provides a stable rekeying platform, so pinning changes stay precise over time. The zinc die cast body keeps the mechanism seated, which helps the bolt and cylinder stay in line with the strike during repeated locking cycles. The choice of 15/16 inch, 1-3/8 inch, or 1-5/8 inch cylinder lengths allows a single lock family to span multiple door builds, making it easier to standardize on one part number series while still matching varying thicknesses. The set screw cylinder release mechanism simplifies cylinder swaps, so keying changes can be carried out as a controlled bench or on-site process without disturbing the surrounding door construction. The key-removable-in-locked-or-unlocked standard function also affects how staff interact with the lock, because it determines whether keys can be withdrawn while the door stands open or must remain inserted until a specific locked condition is set.
