N Series Pin Tumbler Deadbolt Door Lock, Flat Black, Keyed to KA101 Key, 15/16" Cylinder Length

N Series Pin Tumbler Deadbolt For Doors

N Series pin tumbler deadbolt describes a door lock built around the N Series keyway, so it ties directly into systems already using that keyway and keeps key control consistent across related openings. Olympus Lock, Inc. brands this deadbolt, so it matches other Olympus hardware choices on jobs that standardize around that manufacturer. The flat black finish defines the visual look of the cylinder and body, which matters when you are matching existing black hardware or creating a uniform design line. A solid brass pin tumbler cylinder sits at the core of this lock, which provides a familiar cylinder format for locksmiths and installers setting masterkey or stock keying layouts. The deadbolt uses a zinc die cast body, so the main housing combines metal strength with a stable casting shape that seats reliably into the prepared door cutout.

Deadbolt Details That Support Real Workflows

• The deadbolt can be keyed together with other N Series locks, which lets you run one key across related locks on a project and reduce the number of key changes for end users.
• A rekeyable set screw cylinder release mechanism allows cylinder changes in the field, so you can adjust keying without pulling the entire lock body out of the door.
• The lock passed ANSI/BHMA A156.11 Grade 1 performance requirements, so you are working with a unit that has been tested to a defined deadbolt performance standard.
• The cylinder is keyed to KA101 in this version, which ties directly into KA101 master charts where that key number is already the standard for a facility or group of openings.
• The key is removable in either the locked or unlocked position in its standard function, so you can operate and remove the key in whichever position suits the door use pattern.

Door Lock Cylinder Fit And Keying Layout

The cylinder length of 15/16 inch on this deadbolt describes how far the cylinder extends through the door, which lets you choose the correct length relative to the door thickness and trim stack on the job. A barrel diameter of 7/8 inch defines the hole size needed to receive the cylinder, so door prep can follow that measurement for a snug and predictable fit. The stock keying listed as KD/KA - 4 pin standard outlines how the basic cylinders are pinned, which matters when you are matching to existing 4-pin N Series systems or planning rekey work. The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, anchors this deadbolt into a known key family that many shops and locksmiths already stock.

Using This Flat Black Olympus Deadbolt In Practice

Where This N Series Deadbolt Is Typically Applied

This deadbolt sits in the Deadbolt Locks product class, so it is meant for door applications where a separate deadbolt is preferred instead of a latch-only lock. The flat black finish supports projects where visual hardware contrast or a dark, uniform look across door components is part of the design requirement. Because the deadbolt can be keyed together with other N Series locks, it fits into keyed systems where cam locks, drawer locks, or other N Series products already define how keys are allocated. The KA101 keyed setup targets openings that share the KA101 key number, which is useful when you are building or expanding a keyed-alike group on a site. Stock KA numbers such as 101, 103, 107, and 915 reflect common keyed-alike groupings in this N Series family, so this cylinder line plugs into those patterns when those numbers are specified on plans.

Why These Deadbolt Details Support Consistent Results

The ANSI/BHMA A156.11 Grade 1 performance listing, equivalent to E07121(100DR), gives you a defined performance benchmark, which helps standardize product choice when spec sheets call out that grade for deadbolts. The rekeyable design using a set screw cylinder release mechanism means the cylinder can be released without disturbing the full lock case, which reduces door handling time when keying must be changed on occupied openings. A solid brass pin tumbler cylinder supports consistent pinning work, so keying, masterkeying to 5-pin standard, and grand masterkeyed options track cleanly with N Series pinning charts. The note that masterkeyed systems use 5-pin standard shows how this cylinder family supports layered key control, which matters in multi-level masterkey projects. Standard function behavior, where the key is removable in the locked or unlocked position, lets you match user expectations on doors that must be locked or unlocked without trapping the key in either position.
