Schlage ND73LD Spa 626 Corridor Lock Sparta Lever

Product Description

The SCHLAGE ND73LD SPA 626 is a Grade 1 commercial corridor lock fitted with the Sparta lever trim and finished in satin chrome (626). Designed for high-traffic door openings in commercial and institutional buildings, this unit ships less cylinder, meaning the installer supplies and keys the core separately. The non-handed design simplifies inventory and installation by fitting doors of any swing direction without modification. Grade 1 is the highest duty rating under ANSI/BHMA standards, making this lock appropriate for demanding applications where reliability and security are required.

This corridor lock is intended for commercial interior corridor doors where access control is needed from both sides. Typical installations include office buildings, schools, healthcare facilities, and government buildings. The less-cylinder configuration is common on projects where a facility manager specifies a master-keyed system or where a specific proprietary core will be field-installed by a locksmith or security contractor. The Sparta lever profile provides a clean, institutional aesthetic that meets ADA lever requirements for accessible hardware.

Key Features

• ANSI/BHMA Grade 1 duty rating for heavy commercial use
• Sparta (SPA) lever trim with satin chrome 626 finish
• Less cylinder configuration allows installer-supplied core keying
• Non-handed design fits left-hand or right-hand door swings without adjustment

Compatibility

Designed as an OEM-style commercial corridor lock for standard ANSI prep doors. Compatible with ND-series cylindrical chassis components; specific cylinder and core compatibility should be confirmed with the keying system in use on the project.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware installer familiar with ANSI cylindrical lock prep dimensions. Verify the door prep matches the required backset and cross bore before installation. Because this unit ships less cylinder, the appropriate core must be sourced and installed separately before the lock is operational. Always confirm that the finished installation meets applicable building codes and ADA accessibility requirements.
