N Series Pin Tumbler Deadbolt Door Lock, Flat Black, Keyed to KA103 Key, 15/16" Cylinder Length

N Series Pin Tumbler Deadbolt For Secure Doors

N Series pin tumbler deadbolt gives you an Olympus Lock, Inc. cylinder matched to the N Series key system, so it ties directly into existing N Series keyed installations where keyed coordination matters across multiple openings. The flat black finish identifies this unit visually as the SAP-described DEADBOLT, DOOR, KA103, FLAT BLACK, helping you match it to flat black hardware on the same project for a consistent appearance. The cylinder is keyed to KA103, so every lock on this keying scheme uses the same key when you need shared access on a job. Stock KA numbers 101, 103, 107, and 915 define how the keying system is organized, which is useful when you are building or expanding a keyed-alike and masterkey plan. The 15/16 inch cylinder length option lets you select a cylinder size suited to door thickness and hardware layout where this dimension is specified.

Deadbolt Details That Support Daily Use

• The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, lets this deadbolt operate within that established key platform, which simplifies key management when you already use that system.
• The cylinder is a solid brass pin tumbler design, so the working core uses brass components, which supports smooth key operation when properly keyed within N Series applications.
• The zinc die cast body gives the lock case a rigid housing, which supports the deadbolt mechanism during operation in typical door installations.
• Keying can be coordinated with other N Series locks, so you can plan matched key control across cabinet or door locks that share this keyway.
• The lock is easily rekeyable via a set screw cylinder release mechanism, which allows a technician to change the keying configuration on site when keying requirements change.
• The product has passed ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), which indicates it has been tested to that standard duty level.

Installation And Function Details For Fit

The barrel diameter is 7/8 inch, so the door preparation must provide a 7/8 inch cylinder bore for proper seating of this N Series pin tumbler deadbolt. Cylinder length options of 15/16 inch, 1-3/8 inch, or 1-5/8 inch describe how far the cylinder body extends, which matters when matching the lock to door thickness and any applied hardware trim in the opening. The standard function allows the key to be removed in the locked or unlocked position, so users can leave the cylinder without a key present after locking or unlocking, depending on how access is managed. Standard function locks are non-handed, which simplifies layout because the same part can be used on either side orientation without separate left- and right-hand versions on the truck.

Using This Olympus Deadbolt In Real Projects

Where This N Series Deadbolt Is Applied

This Olympus deadbolt is part of the Locks and Latches class under deadbolt locks, which positions it for door applications that call for a cylinder-driven deadbolt in that category. The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, connects it directly with installations that already rely on those key platforms, so it can be specified when extending those keyed systems to new doors. Keying can be set to KD or KA in a 4-pin standard configuration, which defines whether each cylinder has a different key or shares a key within a keyed-alike group. Stock KA numbers 101, 103, 107, and 915 provide defined keyed-alike groups, so this KA103 version slots into the 103 group where that scheme is already documented for a facility or project.

Why These Deadbolt Details Support Consistent Results

Rekeyable construction using a set screw cylinder release mechanism means the cylinder can be reset to a new key configuration while using the same lock body, which supports long-term key system adjustments without replacing the entire deadbolt. The solid brass pin tumbler cylinder provides a precision keying platform, which supports cut-key accuracy and predictable operation when keys match the N Series design. Passing ANSI/BHMA A156.11 Grade 1 performance requirements, equivalent to E07121(100DR), indicates the lock has been evaluated to that specific standard, which helps specifiers align it with written Grade 1 requirements in project documents. The non-handed standard function simplifies stocking and installation because the same Olympus Lock, Inc. part number can be applied on either hand of door, which streamlines ordering and field deployment. The flat black SAP description reference helps visually coordinate with other flat black components, which is useful when matching job schedules that call out that finish.

Keyed Function And Fit Questions For This Deadbolt

Selecting This Deadbolt For N Series Projects

The N Series pin tumbler deadbolt, keyed to KA103 with an N Series keyway, connects directly with door schedules that specify that key platform. The zinc die cast body and solid brass cylinder provide the defined construction this Olympus Lock, Inc. part is built around. Cylinder length and 7/8 inch barrel diameter dimensions pinpoint the door preparation and projection needed for alignment with this lock. For projects organized around ANSI/BHMA A156.11 Grade 1 deadbolt requirements, this 100-US1978-103 model can be chosen where that standard and an N Series system are specified.
