8'' x 14 1/2'' durable Glow-In-The-Dark0.125 Acrylic sign mounts flat outward 3 1/2'' away from the wall at a 45° angle to notify employees and staff of an exit with 180° visibility. Unsurpassed in reliability, glow safety grade signage is the choice for emergency egress systems. Since these signs absorb and store energy from ambient light, they are immediately visible in sudden blackout conditions. Features pre-drilled mounting holes for fast and easy installation.
