Hager 3570 26D Wtn Sfic Classroom Cylindrical Lock

Product Description

The HAGER 3570 26D WTN SFIC is a Grade 2 classroom cylindrical lock configured with an SFIC (Small Format Interchangeable Core) prep and supplied less core, meaning the lock body is ready to accept a compatible SFIC cylinder without including one. It features the Withnell lever with rose trim in a satin chrome finish. This hardware is designed for classroom security functions, allowing the lever to be locked from the outside with a key while the inside lever remains free for egress. It is installed by commercial door hardware technicians and locksmiths in educational and institutional settings.

This lock is intended for commercial interior doors in classroom and institutional applications where a standard Grade 2 cylindrical lock with an interchangeable core platform is required. The less-core configuration allows facility managers and security administrators to supply and install their own SFIC cylinder from an existing keying system, making it well suited for schools, government buildings, and facilities operating a master key or access control program built around the small format interchangeable core standard.

Key Features

• Grade 2 classroom function locks outside lever by key while maintaining free inside egress lever
• SFIC prep accepts small format interchangeable cores from compatible manufacturers
• Supplied less core, allowing integration into an existing keying or access control platform
• Withnell lever with rose trim for a clean, institutional aesthetic
• Satin chrome (26D) finish for durability and corrosion resistance in high-traffic environments

Compatibility

Designed as an OEM-style replacement or new-installation cylindrical lock for commercial doors requiring a Grade 2 classroom function with small format interchangeable core preparation.

Installation Notes

Installation should be performed by a licensed locksmith or qualified door hardware technician familiar with commercial cylindrical lock hardware. Ensure the door is properly prepared with the correct cross bore, edge bore, and strike plate location per ANSI/BHMA standard dimensions before installation. The latch and strike should be aligned and tested for smooth operation before the door is returned to service. The SFIC core must be ordered and installed separately; do not operate the lock without a core installed in a secured facility.
