MikroTik CA433U Internal Case – Black Networking Enclosure

MikroTik CA433U is an aluminium indoor enclosure for the RouterBOARD RB433 series and RBM33G platform, designed for interior installations where mechanical protection, RF antenna connector access and a dedicated USB opening are simultaneous requirements. Commonly used in indoor multi-radio wireless deployments requiring external antenna connectors and USB port access for 3G/4G modems or storage, it provides a professional and flexible mounting solution for varied hardware configurations.

The enclosure features three openings for N-female Bulkhead connectors or swivel antennas plus a dedicated USB cutout, enabling external antenna connection and USB device access without additional enclosure modifications. The updated revision is slightly taller than previous versions, ensuring compatibility with a wider range of taller miniPCI card models. Interchangeable faceplate stickers ship in the box to correctly label the ports in use according to the specific hardware configuration, maintaining a professional appearance regardless of the installed card combination.

CA433U is compatible with the RB433 series and the RBM33G platform, covering two generations of MikroTik equipment widely used in indoor wireless and mobile connectivity deployments. Black aluminium construction contributes passive heat dissipation and provides mechanical protection superior to plastic enclosures. The black finish delivers a discreet, professional appearance well suited for offices, equipment rooms and indoor technical spaces.

Recommended for indoor RB433 and RBM33G deployments with multi-radio configurations requiring external N-female antenna connectors and USB access, for environments where compatibility with taller miniPCI cards matters for specific hardware configurations, for installations where a USB 3G/4G modem serves as a mobile connectivity source, and for integrators standardizing indoor RB433 and RBM33G installations with a dedicated enclosure providing clear visual port identification through the included faceplate stickers.
