N Series Pin Tumbler Deadbolt For Secure Doors

N Series pin tumbler deadbolt describes a door lock built around the N Series key system, which gives installers a defined keying platform for keyed different, keyed alike, or master key setups in the same facility. The deadbolt uses a solid brass pin tumbler cylinder, which provides a precise key interface that supports repeatable keying work across multiple locks. Its body is zinc die cast, giving a rigid housing that supports the cylinder and bolt under normal door use. The cylinder options of 15/16 inch, 1-3/8 inch, or 1-5/8 inch length allow selection for doors or panels that need different back side reach while using the same N Series key plan. The barrel diameter of 7/8 inch sets the bore size target, so fabricators can plan drilling or machining operations around a consistent hole dimension.

Deadbolt Details That Support Real-World Use

• The lock is part of the Olympus N Series, so it can be keyed together with other N Series locks, which helps shops run one coordinated key platform across deadbolts and related locks.
• The cylinder is easily rekeyable via a set screw cylinder release mechanism, which lets locksmiths and maintenance teams adjust keying in the field without replacing the full lock body.
• The deadbolt has passed ANSI/BHMA A156.11 Grade 1 performance requirements, so specifiers can match it to projects that call for Grade 1 deadbolt performance under the E07121(100DR) standard function.
• The standard function allows the key to be removable in the locked or unlocked position, which gives users flexibility in how they operate and secure the door with the same core setup.
• The lock is master keyed with a 5 pin standard layout and grand master keyed availability, which lets security planners build multi-level key hierarchies from a common cylinder design.

Deadbolt Cylinder And Door Fit Considerations

The 7/8 inch barrel diameter on this deadbolt defines the bore size needed in the door or panel, which streamlines layout for drilling jigs and CNC patterns. Cylinder lengths of 15/16 inch, 1-3/8 inch, or 1-5/8 inch give options to match different door thicknesses while keeping the same N Series keyway, which simplifies stocking for installers who service varied openings. The keyway is N Series, equivalent to the National D4291 4-pin or D4292 5-pin system, so technicians familiar with those systems can work directly with this lock using their existing pinning and key-cutting processes. Satin brass finish on the cylinder provides a defined appearance target when coordinating with other satin brass components in the opening.

Using This Olympus Deadbolt In Door Projects

Where This N Series Deadbolt Is Typically Applied

This Olympus N Series pin tumbler deadbolt is a deadbolt door lock from the deadbolt locks product class, so it fits applications that require a separate locking point beyond a latch. Its satin brass presentation suits jobs aiming for a brass hardware look across doors. Because it is part of the Olympus N Series, it can be keyed together with other N Series locks, which is useful when a project calls for a unified key platform across cabinets, doors, and related lock points. The stocked keying of KD/KA 4 pin standard and stock KA numbers 101, 103, 107, and 915 support common keyed alike groupings in multi-door installations that share a user key pattern.

Why The Rekeyable N Series Design Matters

The easily rekeyable design using a set screw cylinder release mechanism means the cylinder can be rekeyed without changing the zinc die cast body, which saves labor and material when key changes are needed over the life of the door. The solid brass pin tumbler cylinder supports both 4 pin standard stock keying and 5 pin standard master keyed setups, so a single cylinder platform can serve simple single-user doors as well as multi-level master key systems. Passing ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), signals that the lock has been tested to a high performance level, which helps specifiers align it with demanding commercial or institutional door requirements. The option for grand master keyed systems allows security managers to extend control beyond standard master key tiers while still working within the N Series keyway. The standard function, with key removable in locked or unlocked position, supports operational habits where staff may withdraw the key after locking or after unlocking depending on their workflow, without changing the internal function of the lock. The satin brass finish gives a consistent color and surface appearance that aligns with satin brass hinges, pulls, and other visible hardware in the same opening.
