N Series pin tumbler deadbolt gives a keyed deadbolt solution that matches other Olympus N Series locks, so one system can be used across multiple lock points. The oil rubbed bronze finish provides a dark, traditional appearance that suits many door styles where visual consistency matters. The deadbolt uses a solid brass pin tumbler cylinder, which offers a familiar key feel for installers working with standard N Series key systems. A zinc die cast body supports the cylinder, creating a rigid housing that helps the deadbolt operate predictably under normal door use. The design is built as a door deadbolt lock, so it focuses on bolt control rather than latching, which suits applications where the primary need is secure locking instead of passage. This model is keyed different in stock keying, so each lock has its own combination when ordered that way.
The deadbolt uses a cylinder with a 7/8 inch barrel diameter, which sets the bore size needed in the door or lock prep, helping installers align drilling with existing N Series layouts. Cylinder length options of 15/16 inch, 1-3/8 inch, or 1-5/8 inch provide several depth choices, so the same deadbolt pattern can be adapted to different door thicknesses or hardware stacks that require more reach. Because the cylinder is solid brass with a pin tumbler design, keying and pinning follow standard pin tumbler practices, which streamlines bench work for locksmiths familiar with N Series systems. The zinc die cast body surrounds the cylinder, forming a solid unit that seats into the prepared opening, so the deadbolt feels stable once mounted. The oil rubbed bronze finish on exposed parts ties the lock into doors and trim using a similar dark bronze look.
This Olympus N Series pin tumbler deadbolt door lock suits projects that already use N Series keyways, because it can be keyed together with other N Series locks for unified access control. The ability to use KD or KA 4-pin stock keying lets the same deadbolt serve individual doors or groups of doors under one key number, which is practical for offices, workrooms, or storage areas sharing traffic patterns. The ANSI/BHMA A156.11 Grade 1 performance rating, equivalent to E07121(100DR), aligns the lock with demanding applications where deadbolts see frequent operation, so it fits doors in commercial or institutional environments built to that standard. Oil rubbed bronze finish supports jobs where hardware appearance must match existing bronze levers, knobs, or hinges throughout a space. Because the standard function is non-handed, the same part can be used on either left- or right-hand doors across a project.
The solid brass pin tumbler cylinder in this deadbolt gives locksmiths a familiar platform for pinning, so keyed different, keyed alike, and masterkeyed setups can be built using known N Series techniques. Stock KA numbers 101, 103, 107, and 915 provide defined keyed-alike groups, helping planners assign predictable key patterns to zones or user groups. The rekeyable design, using a set screw cylinder release mechanism, lets technicians remove and change the cylinder without replacing the entire lock body, which simplifies future rekeys when tenants or access requirements change. With masterkeyed 5 pin standard and grand masterkeyed options available, the same N Series platform can scale from simple one-door jobs to layered key systems with multiple hierarchy levels. Key removable in locked or unlocked positions on the standard function allows flexible routines during service, since technicians can lock, unlock, or cycle the bolt while keeping the key workflow consistent.
This deadbolt uses the N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, so it fits projects built around the same key platform.
This N Series pin tumbler deadbolt is easily rekeyable via a set screw cylinder release mechanism, allowing cylinder changes without replacing the main lock body.
The deadbolt has passed ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), which aligns it with demanding commercial specifications.
The keyed different stock keying means each lock has its own key pattern by default, which suits doors needing separate keys unless grouped under a keyed alike plan.
The 7/8 inch barrel diameter defines the bore size in the door or prep, so installers can match drilling to this dimension when laying out new or retrofit work.
Cylinder lengths of 15/16 inch, 1-3/8 inch, and 1-5/8 inch let the same deadbolt pattern adapt to various door thicknesses or trim stacks that demand deeper cylinders.
The Olympus N Series pin tumbler deadbolt door lock in oil rubbed bronze ties directly into N Series keyway systems, so projects using that platform gain a matching deadbolt option. With ANSI/BHMA A156.11 Grade 1 performance and a solid brass cylinder in a zinc die cast body, the lock suits demanding door locations that expect consistent operation. Rekeyable design and multiple cylinder lengths help the same model cover varied door conditions and future key plan adjustments. For jobs needing a keyed different, N Series-compatible deadbolt that aligns with defined KA numbers and a bronze aesthetic, this 100-10B138-KD configuration offers a focused, spec-driven choice.
