N Series pin tumbler deadbolt gives you an Olympus Lock, Inc. cylinder that fits directly into N Series key systems, so shops using that keyway can keep door security on the same platform as other N Series locks. The 1-7/16 inch pin tumbler deadbolt design provides a compact lock body that suits door applications where you need a separate deadbolt rather than a latch function. The satin brass finish delivers a consistent appearance for projects specd with brass hardware, which helps keep commercial or residential jobs visually uniform across multiple openings. The body is zinc die cast, so the lock case has a solid, rigid structure for mounting in standard deadbolt cutouts on suitable doors. The solid brass pin tumbler cylinder gives you a robust keying interface that works smoothly with N Series keys in daily use.
The zinc die cast body gives the deadbolt a stable housing that seats firmly when you mount it into the prepared door cutout, supporting smooth bolt action after installation. The solid brass, pin tumbler cylinder is available in 15/16 inch, 1-3/8 inch, or 1-5/8 inch lengths, so you can select a cylinder size that matches door thickness and trim stack, helping the face sit flush with the door surface. A 7/8 inch barrel diameter defines the bore needed for the cylinder, which matters when you are machining new doors or checking an existing hole for retrofit work. Because the cylinder is retained by a set screw cylinder release mechanism, you can remove and service or rekey the cylinder while leaving the main deadbolt chassis in the door, keeping field time focused on the key system rather than full hardware replacement.
This Olympus deadbolt door lock belongs to the N Series family, so it works well on job sites where cabinets, doors, and other lock points are already keyed on the same N Series keyway. In a multi-opening environment, the ability to key this deadbolt together with other N Series locks means you can align door security with matching cam locks or drawer locks, giving building staff a unified key plan. The ANSI/BHMA A156.11 Grade 1 performance rating supports use in applications that demand a higher performance level, such as commercial or institutional projects where hardware is subject to frequent operation. Satin brass finish makes this deadbolt a practical match for brass hinge and pull schedules, providing a coordinated look across doors that carry both decorative and functional hardware in the same color tone.
The N Series lock keying system, equivalent to National D4291 4-pin or D4292 5-pin, lets you place this deadbolt into established key hierarchies without redesigning your entire key map, which is valuable when working in existing facilities. Stock keying as KD/KA in 4-pin standard gives you both keyed-different and keyed-alike options from the same product line, so you can balance individual door control with shared key access on groups like corridors or suites. Masterkeyed in 5 pin standard and available grand masterkeyed capability add layers of control for projects where different user groups need distinct access levels. The standard function design, with the key removable in locked or unlocked position, allows staff to remove the key immediately after cycling the lock in either state, supporting consistent habits around securing or leaving doors open during daily routines.
The 100-US4138-KD deadbolt is an Olympus N Series pin tumbler deadbolt door lock, so it functions as a separate deadbolt to secure a door rather than as a latch.
The deadbolt uses a set screw cylinder release mechanism, allowing the cylinder to be rekeyed or changed while leaving the lock body installed, which streamlines field rekey work.
The deadbolt passed ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), so it meets a defined high performance level used in commercial hardware specs.
The N Series deadbolt uses an N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, so it integrates with those existing key systems.
The deadbolt cylinder is solid brass and offered in 15/16 inch, 1-3/8 inch, or 1-5/8 inch lengths, which lets you match the cylinder to varying door thickness conditions.
The deadbolt has a standard function where the key is removable in the locked or unlocked position, giving operators flexibility when securing or reopening the door.
