This nightlatch features external key locking with internal keyless egress, meaning it can be securely locked from outside but easily opened from inside without a key. This feature is essential for meeting fire safety regulations, providing quick escape in emergencies while maintaining maximum security from outside threats.

Engineered with a reinforced case, hardened anti-drill plates, and a high-security rim cylinder, the lock delivers superior resistance against tampering and forced entry. The deadlocking mechanism ensures the latch bolt cannot be slipped or manipulated once locked.

Available in sleek polished brass or satin chrome finishes, it complements a variety of door styles. Supplied with 2–3 keys, a strike plate, fixings, and installation instructions, it’s a practical and secure upgrade for any wooden or composite external door.
