HMI cover kits—including the new 20-in. by 16-in. size—feature a rigid design for mounting securely to the outside of any enclosure and provide protection/access to critical components. The kits are UL-recognized and maintain a NEMA 4X seal, making them well suited for applications in harsh environments. They feature solid opaque or clear covers with multiple cover latching options, or a prop arm kit for added convenience.
