Accentra 4780LN Fail Safe Electrified Lever
The Accentra 4780LN Fail Safe Electrified Lever ensures secure access while maintaining safe egress. Deadlocking latchbolt operates by lever on either side, except when power is on, which locks the outside lever. Power off automatically unlocks the outside lever, and the inside lever always remains free for safe exit.
The free-wheeling lever design prevents damage from forced rotation, providing long-lasting durability. This lever is ideal for commercial and institutional doors requiring reliable fail-safe electrified access.
