N Series Pin Tumbler Deadbolt Door Lock, Oil Rubbed Bronze, Master Keyed/Keyed Different, 7/8" Cylinder Length

N Series Pin Tumbler Deadbolt For Doors

N Series pin tumbler deadbolt sets up a keyed door lock that works with other N Series locks in the same key system, so you can plan door security around one consistent keyway across a project. The Olympus Lock, Inc. design uses a solid brass pin tumbler cylinder, which provides a familiar rekeying process for locksmiths and installers used to pin tumbler systems. The cylinder length options of 15/16 inch, 1-3/8 inch, or 1-5/8 inch allow selecting a size that matches the door thickness and hardware stack, supporting proper engagement without overhanging the face of the door. A 7/8 inch barrel diameter gives a clear drilling reference for boring the hole, helping keep layout consistent from opening to opening. The oil rubbed bronze finish establishes a dark, traditional look on the door, so the deadbolt can match other bronze-finished hardware in the same space.

Deadbolt Details That Support Daily Use

• The zinc die cast body provides a rigid lock housing, giving the cylinder and bolt a stable platform so the key action stays consistent when the door is cycled over time.
• The solid brass pin tumbler cylinder creates a precise key interface, which helps maintain smooth operation when the lock is rekeyed within the N Series system during future keying changes.
• The keying that can be matched with other N Series locks allows one key to operate multiple openings set up on that system, which simplifies key control for facilities using the N Series keyway.
• The rekeyable design with a set screw cylinder release mechanism lets the cylinder be removed and reconfigured, so the lock can stay in place on the door while keying is updated.
• The ANSI/BHMA A156.11 Grade 1 performance rating means the deadbolt has passed a recognized performance standard, supporting use in demanding door cycles where a higher grade is specified.

Deadbolt Lock Fit, Keying, And Cylinder Setup

The 7/8 inch barrel diameter of this deadbolt gives a straightforward bore size to follow when preparing the door, so the body seats correctly without excessive play. The available cylinder lengths of 15/16 inch, 1-3/8 inch, or 1-5/8 inch make it possible to match the projection of the cylinder face to the door and trim combination, which helps keep the lock flush and reduces snag points at the opening. The standard function with key removable in either the locked or unlocked position allows the user to remove the key without having to leave the bolt in a specific position, which can streamline operation in day-to-day use.

How This Olympus Deadbolt Works In Practice

N Series Deadbolt Use In Keyed Systems

This Olympus N Series deadbolt uses the N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, so it can sit inside an existing N Series keying structure on a job. Stock keying as KD/KA with 4 pin standard provides flexibility between keyed different and keyed alike setups, which lets a project mix single-door keys with groups of doors on shared keys. The stock KA numbers 101, 103, 107, and 915 identify commonly used keyed alike groups, making it straightforward to specify matching doors within a facility. Masterkeyed cylinders use a 5 pin standard, allowing a hierarchical key structure where master keys work across multiple locks while individual keys are limited, which is useful for separating access between staff levels.

Details That Support Reliable Deadbolt Performance

The rekeyable function using a set screw cylinder release mechanism means the cylinder can be released from the body for rekeying while the main lock case remains fixed on the door, reducing disturbance to the door edge or face during key changes. The zinc die cast body supports the cylinder and bolt components in a solid frame, which helps the deadbolt maintain alignment with the strike when the door is opened and closed repeatedly. Passing ANSI/BHMA A156.11 Grade 1 performance requirements shows the deadbolt design has been tested to a demanding performance level, which matters when specifying locks in higher traffic areas that call for Grade 1 product. The standard function, with the key removable in locked or unlocked positions, lets users secure or open the door and then remove the key without needing to leave it in the cylinder, which can speed up movement through controlled areas.
