721DR No Core Deadbolt Door Lock Body, Satin Chrome, 1-3/8" Cylinder Length

721DR Deadbolt Lock Body For Secure Door Use

721DR no core deadbolt door lock body gives installers a Grade 1-rated lock body ready for small format interchangeable cores, so you can match existing key systems while upgrading hardware. The Olympus Lock, Inc. design passes ANSI/BHMA A156.11 Grade 1 performance requirements, so it supports demanding commercial or institutional installations where tested security and cycle life matter. The satin chrome 26D finish coordinates with common commercial door hardware, helping projects maintain a consistent appearance across doors and millwork. The body is built as a zinc die cast component, providing a solid housing that supports precise cylinder alignment and smooth operation. A barrel diameter of 1-1/8 inch works in typical commercial door prep dimensions, while the 1-3/8 inch cylinder length option suits thicker door constructions or deeper stiles where extra reach is required for proper mounting.

Deadbolt Lock Body Details That Support Jobs

• The lock body retrofits Best 3L, so replacement work on existing Best-style installations can reuse door prep while updating hardware, saving drilling time and keeping door faces cleaner.
• Field reversible function between door and drawer applications allows the same 721DR deadbolt body to serve vertical or horizontal layouts, simplifying truck stock and helping respond quickly to varied cabinet or casework requirements.
• Key removable in locked and unlocked position as the standard function lets facilities use one lock body for flexible key control routines, supporting different security procedures without swapping hardware.
• Acceptance of Best, Arrow, Falcon, KSP, and Schlage small format interchangeable cores lets you keep an established SFIC master key system running while standardizing on this Olympus lock body.
• Compatibility with Medeco Nexgen XT and VIDEX Cyber electronic SFIC cylinders allows upgrades to electronic access control while retaining the same mechanical 721DR housing, helping phased modernization projects.

Deadbolt Installation And Cylinder Fit Details

The 1-1/8 inch barrel diameter on this deadbolt door lock body matches common SFIC-style prep dimensions, so it seats cleanly in doors or casework bored for that size. A 1-3/8 inch cylinder length option gives added reach through thicker door sections, allowing the front to sit flush while the locking components align inside the stile or edge. The zinc die cast body construction supports consistent cylinder positioning, which helps the interchangeable cores seat correctly for reliable key insertion and removal. Because the function is field reversible between door and drawer use, installers can orient the body to match the locking direction of the application without changing the basic hardware.

Where This Olympus Deadbolt Body Fits Best

Why These Deadbolt Details Support Repeatable Results

The small format interchangeable core design allows Best, Arrow, Falcon, KSP, and Schlage SFIC cylinders to seat in the same 721DR housing, so locksmiths can carry one body while servicing multiple key systems. Compatibility with Medeco Nexgen XT and VIDEX Cyber electronic SFIC cylinders means the same mechanical footprint can carry advanced electronic lock cores, keeping door prep and hardware geometry stable across technology upgrades. The standard function, where the key is removable in both locked and unlocked positions, simplifies operation patterns in facilities that use the same key turn for secure and access modes. Field reversibility between door and drawer configurations helps installers align the lock motion with casework design, supporting clean linkage to strikes and bars without additional parts. With a zinc die cast body managing the internal alignment, the cylinder and core position remain consistent across multiple openings, aiding repeat installs and reducing fit adjustments from door to door.
