This 21 RU door is constructed from steel and finished with a black textured powder coat to match the existing rack aesthetics. To facilitate active cooling within the enclosure, the door features both top and bottom venting, providing a 64% vent open area for airflow. This specific model is sized to fit ERK Series enclosures with a height of 35.81 in (91 cm) and a width of 19.44 in (49.4 cm). Because this is a rear door component, ensure your existing ERK enclosure is the 21 RU variant to ensure proper fitment. For installers requiring additional security or replacement parts, the SRD-KEY is available as a compatible accessory.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDesigned exclusively for ERK Series enclosures\u003c\/li\u003e\n\u003cli\u003eProvides 21 RU of vertical mounting space\u003c\/li\u003e\n\u003cli\u003eFeatures top and bottom venting for airflow\u003c\/li\u003e\n\u003cli\u003e64% vent open area for thermal management\u003c\/li\u003e\n\u003cli\u003eBlack textured powder coat steel construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuestions\u003c\/h2\u003e\u003ch3\u003eWill this door fit my ERK enclosure?\u003c\/h3\u003e\u003cp\u003eThis door is designed to fit ERK Series enclosures only.
