The DOOR-S21 model is specifically sized for standard 19-inch rack equipment when mounted within compatible Middle Atlantic enclosures.

Compatibility

This door is designed for use with Middle Atlantic 20-inch wide rack enclosures that support a 21 RU door height. Verify your specific rack model's compatibility before purchase, as door dimensions and mounting mechanisms vary across enclosure series.
