The Miller Edge MU21 safety edge is a compact, pressure‑sensitive electric sensing edge engineered to safeguard commercial sectional doors and material‑handling systems. Built for seamless integration, it mounts directly to the bottom of a door or equipment without a mounting channel and sends an instant signal to stop or reverse movement when lightly touched. Designed for 2‑inch‑thick surfaces, the flexible vinyl jacket wraps around the leading edge and conforms to minor floor irregularities, ensuring reliable triggering even on uneven surfaces. This touch‑sensitive edge enhances safety, helps prevent injuries and equipment damage, and is a standard solution for warehouses and industrial doors.
The MU21 is custom‑built to your specifications, with options for color (gray, black, yellow, yellow/black stripe or chemical‑resistant XR5) and length, and it can mount vertically or horizontally. Five‑ to six‑inch end flaps create a complete seal and can be trimmed for a perfect fit. The sealed assembly is impervious to dust and debris and uses patented Alumaglas™ contact elements with a heavy‑duty reinforced PVC exterior for durability. With monitored and non‑monitored configurations (2‑wire, 4‑wire, Air‑Wave or pneumatic options), a UL 325‑recognized safety rating, one‑year warranty and Made‑in‑USA construction, the MU21 offers versatile customization and proven reliability.
