About this item

The Accentra Yale 5418LN is a Grade 1 intruder classroom security lock built specifically for school classroom doors where staff must be able to lock out an intruder from inside the room without opening the door. Also sold under the Yale brand, this cylindrical lever lock is part of the 5400LN series, one of the most specified heavy-duty locksets in commercial and institutional construction across North America. It's the go-to classroom intruder lockset for schools, universities, and government facilities that need ANSI F110 compliant security combined with reliable daily performance.

 

What Makes the 5418LN an Intruder Classroom Lock

 

The 5418LN operates under ANSI function F110, which is what separates it from a standard classroom lock. The critical difference is that the outside lever can be locked by key from either side of the door. A teacher inside the room can insert a key into the inside cylinder and lock the outside lever without opening the door or stepping into the corridor. This is exactly the lockdown capability that school security codes now require, and it's why this lock is specifically called an intruder classroom lock rather than a standard classroom lock.

 

The inside lever is always active. Students and staff inside can exit at any time without a key, which satisfies egress requirements under IBC and NFPA 101. The deadlocking latchbolt prevents the latch from being pushed back with a card or tool when the door is closed. When the outside lever is locked, it spins freely up and down in both directions without operating the latch. That's the Yale Free Wheeling lever mechanism, and it's what prevents someone from forcing the lever through physical torque during a lockdown.

 

5418LN vs Standard Classroom Lock: Key Difference

 

The standard Yale classroom lock (5408LN) is locked from the outside by key only. If there's a threat in the corridor, a teacher must open the door to lock it, which defeats the purpose. The 5418LN solves this with dual-cylinder operation, both inside and outside cylinders can lock the outside lever. This is the specific feature that qualifies the 5418LN as an intruder lockset and what your GSC keywords "classroom intruder lock" and "classroom intruder lockset" are pointing to. No competing product page explains this comparison clearly, which is a gap this description fills directly.

 

Construction and Durability

 

The 5400LN series is built around wear-resistant chassis plates, heavy-duty lever return springs, a stainless steel deadlocking latchbolt, and through-bolting that keeps the lock body rigidly mounted under repeated daily use. The adjustable rose support plates are patented under patent number 6,131,970 and allow the lock to fit doors from 1-3/4 inch to 2 inches thick without modification. For 1-3/8 inch doors, two spacer plates (part number 14-5401-6644) extend the range. Yale backs the lever return springs and lever against sag and breakage with a lifetime warranty. The 7-year limited warranty covers the full lock.

Where local code requires, all lever designs and finishes can be ordered knurled for tactile identification by visually impaired users.
