N Series Pin Tumbler Deadbolt Door Lock, Oil Rubbed Bronze, Keyed Different, 15/16" Cylinder Length

N Series Pin Tumbler Deadbolt For Door Security

N Series pin tumbler deadbolt describes a door lock built around the N Series keyway, so it works within the same key system as other N Series locks where matching key control is required. The Olympus Lock, Inc. 100-10B78-KD deadbolt uses a solid brass pin tumbler cylinder, which provides a familiar pin stack layout for locksmith rekeying and consistent key operation in service. The body is zinc die cast, giving the lock a solid housing for the cylinder during repeated locking cycles on the door. An oil rubbed bronze finish presents a dark, traditional appearance on the door surface, which matters when the deadbolt needs to align with other bronze-finished hardware on the project. The cylinder length of 15/16 inch defines how the lock seats through the door preparation, so the specified dimension guides door boring depth and trim alignment work.

Deadbolt Details That Support Real Job Needs

• The keying can be set up so it can be keyed together with other N Series locks, which allows a keyed system using the same N Series keyway across multiple lock positions on a project.
• The lock is easily rekeyable via a set screw cylinder release mechanism, which lets a locksmith or shop technician change keying in the field without replacing the entire deadbolt body.
• The product has passed ANSI/BHMA A156.11 Grade 1 performance requirements, which indicates the deadbolt is tested to a recognized performance level for commercial-grade deadbolt locks.
• The key removable in locked or unlocked position standard function gives flexibility in how the cylinder is used, which helps when a particular door requires key retention behavior that matches other N Series hardware.
• The cylinder uses the N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, which matters when matching existing key systems that already use these National-style keyways.
• The stock keying KD or KA 4 pin standard and available stock KA numbers 101, 103, 107, and 915 define how locks in inventory can be grouped under common keys, which helps plan keying charts and door schedules.

Installation, Cylinder Length, And Keying Setup

The cylinder length of 15/16 inch on this deadbolt defines how it fits through the drilled door hole, so installers can align door thickness and backset preparation to the specified cylinder dimension. The barrel diameter of 7/8 inch describes the required bore size, which guides drilling or machining operations when preparing new doors or retrofitting existing ones. The set screw cylinder release mechanism allows cylinder removal for rekeying, which lets a locksmith work from the lock edge rather than pulling the entire assembly from the door. The non-handed standard function means the same lock body works on both door handing orientations, which simplifies stocking and reduces the need to sort parts by left- or right-hand use.

Using This Olympus N Series Deadbolt In The Field

Where The N Series Pin Tumbler Deadbolt Fits Best

This deadbolt belongs to the deadbolt locks product class and is listed for door applications, so it fits projects where a dedicated deadbolt is required rather than a latch function. The oil rubbed bronze finish matches other oil rubbed bronze door components, which is useful when hardware schedules call for consistent bronze tones on visible door faces. The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, ties this lock into key systems already using those National profiles, so existing keys can be coordinated by a locksmith across multiple openings. The ability to be keyed together with other N Series locks means one keyed system can serve deadbolts and other N Series hardware in the same facility, which simplifies user key rings and key control plans on site.

Why Rekeyable Design And Grade 1 Rating Matter

The easily rekeyable design using a set screw cylinder release mechanism allows the solid brass cylinder to be removed and re-pinned, which means key changes can be handled by service teams without replacing the zinc die cast body installed in the door. The ANSI/BHMA A156.11 Grade 1 performance requirement rating shows the deadbolt has been tested to a high performance tier for deadbolt locks, which matters when specifying hardware in commercial or higher-duty environments. The pin tumbler cylinder supports both 4-pin stock keying and 5-pin masterkeyed or grand masterkeyed setups, which lets key systems expand from simple keyed different doors to more complex masterkey hierarchies as a facility grows. The standard function with key removable in locked or unlocked position defines how the user interacts with the cylinder, which allows hardware specifiers to match the field behavior to other N Series installations that share the same function notes.
