N Series Pin Tumbler Deadbolt For Secure Doors

N Series pin tumbler deadbolt installs as a door deadbolt where an N Series cylinder is required and a 7/8 inch barrel diameter must match the prep. The lock uses a solid brass pin tumbler cylinder, which provides a familiar key feel and straightforward pin-based keying for shops already working with pin tumbler systems. The body is zinc die cast, so the housing stands up to normal door use while still machining consistently in production work. This model is keyed to KA103, which lets you match it to other locks on the same KA103 key number in the N Series family. The finish is oil rubbed bronze, so the lock presents a dark architectural look that coordinates with similar bronze hardware on doors and cabinets.

Deadbolt Details That Support Keyed Systems

• The N Series keyway, equivalent to National D4291 4-pin or D4292 5-pin systems, lets you fold this deadbolt into existing N Series keying plans where those keyways are already in service.
• Keying can be set KD or KA in stock 4-pin form, so you can order locks keyed differently or alike to organize door groups by area or function around a single N Series key.
• The lock is easily rekeyable via a set screw cylinder release mechanism, which allows the cylinder to be changed or rekeyed on site without replacing the entire deadbolt body.
• ANSI/BHMA A156.11 Grade 1 performance compliance means the deadbolt has passed a recognized performance standard, supporting use where Grade 1 deadbolt performance is called for.
• The standard function allows the key to be removable in the locked or unlocked position, which simplifies operation where staff lock and unlock doors frequently during a shift.

Door Lock Mounting And Cylinder Size Use

The deadbolt uses a 7/8 inch barrel diameter, which fits door or panel preps bored for that cylinder size in metal or wood applications using this diameter standard. Cylinder length options of 15/16 inch, 1-3/8 inch, or 1-5/8 inch allow you to match the cylinder projection to the door thickness, so the face of the cylinder sits correctly without excess overhang. The key removable in locked or unlocked position function means the operator can lock the door and remove the key immediately or leave it keyed while unlocked, depending on how the opening is managed day to day.

How This Olympus Deadbolt Fits Real Jobs

Using This Oil Rubbed Bronze N Series Deadbolt

This Olympus Lock, Inc. deadbolt is part of the N Series, so it slots into projects already using that N Series keyway and the related National D4291 or D4292 systems. The stock KA numbers of 101, 103, 107, and 915 identify common keyed-alike groups, and this specific unit is keyed to KA103, which matters when you are expanding a keyed-alike zone under that KA number. The cylinder is a solid brass pin tumbler design, so locksmiths and millwork shops work with a familiar construction when pinning or servicing cores. Oil rubbed bronze finish lets the lock visually tie into darker door pulls, hinges, and trim that share that bronze look.

Supporting Rekeying, Masterkeying, And Performance Needs

The deadbolt is easily rekeyable by means of a set screw cylinder release mechanism, giving you a direct way to change cylinders without taking out the full housing. The product can be keyed together with other N Series locks, allowing multiple openings to operate on coordinated keying while using the same basic cylinder family. Stock keying is KD or KA using a 4-pin standard layout, and masterkeyed setups use a 5-pin standard configuration, so large key systems can be organized with master and change keys. Grand masterkeyed capability is also available, supporting tiered key control where multiple master levels are required across a site. The lock has passed ANSI/BHMA A156.11 Grade 1 performance requirements and is equivalent to E07121(100DR), so it aligns with a clearly defined Grade 1 deadbolt performance category when project documents call out that level.
