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.
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.
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.
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.
The Olympus 100-10B78-KD deadbolt uses a 15/16 inch cylinder length, which determines how it fits through the door bore and aligns with the door thickness during installation.
The deadbolt uses the N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, which allows it to participate in key systems built around those National-style profiles.
The N Series pin tumbler deadbolt can be keyed together with other N Series locks, so multiple locks can operate on the same key within an N Series keying plan.
The 100-10B78-KD deadbolt is easily rekeyable via a set screw cylinder release mechanism, allowing removal of the solid brass cylinder for re-pinning while leaving the body in the door.
The Olympus N Series deadbolt has passed ANSI/BHMA A156.11 Grade 1 performance requirements, indicating it meets a recognized Grade 1 standard for deadbolt performance.
The deadbolt is stocked KD or KA 4 pin standard, with stock KA numbers 101, 103, 107, and 915, which defines how groups of locks can share common keys.
The Olympus N Series pin tumbler deadbolt in oil rubbed bronze brings a zinc die cast body, solid brass cylinder, and ANSI/BHMA A156.11 Grade 1 performance to door applications where N Series key control is required. The 15/16 inch cylinder length and 7/8 inch barrel diameter define the door preparation, while the rekeyable set screw release mechanism supports ongoing key changes. With keyed different stock keying options and the ability to work within N Series systems, this deadbolt aligns with door schedules that call for coordinated N Series hardware and a traditional oil rubbed bronze appearance.
