Black/white Jamb plate

Black and white jamb plate signs are one of the most widely used styles for marking floor numbers on elevator door frames. Installed on both sides of elevator doors, these signs provide sharp contrast with white text on a black background (or black text on a white background), ensuring maximum visibility from any angle. They help building occupants, inspectors, and firefighters quickly identify floors, even in dim lighting or emergency situations. The clean, simple design makes them a durable and versatile choice for high-rise residential buildings, offices, and institutions.

Jamb plates are required by FDNY, NFPA, IBC, and many local building codes to identify each floor level for emergency response and safety. Black/white jamb plates combine functionality with compliance, offering easy readability and long-lasting durability. Available in aluminum, plastic, or photoluminescent options, these signs ensure that floor numbers remain clear and visible during power outages, fires, or smoke conditions. By installing black/white jamb plate signs, property owners meet code requirements while maintaining a professional look throughout their building.
