Schlage ND70JD Ath 625 Grade 1 Classroom Lock

Product Description

The SCHLAGE ND70JD ATH 625 is a Grade 1 classroom lock designed for institutional and commercial door hardware applications. Built on the ND-series cylindrical platform, it features the Athens lever trim and is supplied in an FSIC (Full Size Interchangeable Core) prep without a core installed, allowing facilities to use their existing keying system. The bright chrome finish (625) provides a clean, corrosion-resistant appearance suited to high-traffic environments. This lock is non-handed, meaning it installs on either hand of door without modification.

This lock is intended for classroom, office, and institutional doors where a standard classroom security function is required. The classroom function keeps the exterior lever locked by default, allowing free egress from the inside at all times while controlling entry from the outside. Typical installations include K-12 schools, universities, government facilities, and commercial office buildings. A licensed locksmith or credentialed facilities technician typically handles FSIC core installation and door prep work.

• Less core configuration allows facilities to supply their own keying core
• Athens lever design meets ADA lever handle requirements
• Non-handed design installs on left-hand or right-hand doors without modification

Compatibility

Designed as an OEM-style replacement or new-installation cylindrical lock for commercial and institutional doors requiring a Grade 1 classroom function with FSIC prep compatibility.

Installation Notes

Installation should be performed by a licensed locksmith or qualified facilities technician familiar with commercial cylindrical lock hardware. Verify door prep dimensions and backset before installation, as incorrect prep can prevent proper latch and deadlatch function. The FSIC core must be installed separately and should only be handled by personnel authorized under the applicable key control program. Always follow local building codes and applicable ANSI hardware standards when selecting and installing door hardware for life-safety or egress applications.
