N Series Pin Tumbler Deadbolt Door Lock, Satin Brass, Keyed to KA103 Key, 7/8" Cylinder Length

N Series Pin Tumbler Deadbolt For N Keyway

N Series pin tumbler deadbolt defines this Olympus Lock, Inc. door deadbolt as a keyed cylinder using the N Series keyway, so it matches N Series key systems where a consistent key profile matters on the job. This deadbolt door lock uses a solid brass pin tumbler cylinder, which provides a precise pin-stack interface for dependable key operation in daily use. The body is zinc die cast, giving the lock housing a rigid structure that supports the cylinder and strike alignment over time. A satin brass finish identifies the lock visually as brass-toned, which helps installers match it to satin brass door and cabinet hardware in a project. The cylinder uses a 7/8 inch barrel diameter, so it fits openings designed around that standard cylinder bore size.

Deadbolt Details That Support Key Control

• This deadbolt is keyed to KA103, so multiple 100-US478-103 locks set to KA103 can operate from the same key for controlled keyed-alike groups on a project.
• The keying system can be keyed together with other N Series locks, allowing one N Series keyway plan to operate this deadbolt and other N Series hardware where unified key control is required.
• The cylinder is easily rekeyable via a set screw cylinder release mechanism, so cylinders can be rekeyed on site without replacing the entire lock body, keeping hardware in service during keying changes.
• The lock passed ANSI/BHMA A156.11 Grade 1 performance requirements, so it meets a tested level of operational performance suited to demanding commercial or institutional installations.
• The standard function provides key removable in locked or unlocked position, so staff can remove the key after setting either state, which supports flexible key handling around secured doors.

Deadbolt Cylinder And Function For Installation

The key removable in locked or unlocked position function lets installers set up doors where keys can be drawn after confirming the bolt position.
