Classroom Function Lever Lockset

This cylindrical lockset is built for classroom doors that must stay locked from the outside while allowing free egress from inside. Heavy-gauge steel construction meets ANSI/BHMA A 156.2 Grade 1 for high-traffic commercial use. The dull chrome 626 finish resists wear in institutional environments. It fits doors 1-3/8 to 1-3/4 inches thick with a 2-3/4 inch backset.

Upgrade From Residential Or Light-Duty Hardware

Switching to this Grade 1 lockset is warranted when a building moves from light residential traffic to daily student or staff flow. The three-hour fire rating and UL/cUL listing satisfy code requirements that lighter locks cannot meet. SFIC core compatibility lets a facility standardise on one key system across multiple openings. ADA-compliant lever operation removes the barrier posed by knob hardware.

Standard Cylindrical Prep With Strike Included

Installation follows the common 2-3/4 inch backset and 3-1/2 inch rose dimensions, so existing door prep often matches without new boring. The supplied 2-1/4 by 4-7/8 inch strike aligns with standard metal-frame cut-outs. The most frequent issue is overlooking the less-cylinder designation — the lock ships without an SFIC core, so one must be sourced separately. Verify door thickness and handing before mounting to avoid rework.

Questions about this item

What backset and door thickness does the 4700LN classroom lock require?

The lock fits a 2-3/4 in. backset and doors 1-3/8 to 1-3/4 in. thick.

How is the 4700LN lock installed and what step is often missed?

Install the cylindrical chassis into the 2-1/4 x 4-7/8 in. strike prep, then secure the rose; the SFIC cylinder must be inserted and tested for classroom function before final tightening.

When will the SFIC cylinder in this 4700LN lock need replacement?

Replace the SFIC cylinder when key wear causes binding or when rekeying is required; the Grade 1 steel chassis and 3-hour fire rating remain valid after cylinder swap.
