-The box body has a square groove structure, and the internal bottom plate has two types of heat dissipation openings: multiple long rectangular grooves and dense circular small holes, which enhance air circulation and dissipate heat for the built-in electronic components.

-Two bent fixing ears with circular holes extend from the left side for screw installation and fixation on the cabinet/equipment bracket.

-There is a hinge mounting piece with two screws on the right side, which is used to connect with the matching flip panel to achieve flip opening and closing, facilitating internal equipment maintenance.

-There are raised edges around, forming a storage space for electronic components such as circuit boards, small modules, routers, etc.

The overall workmanship is neat, belonging to industrial customized sheet metal parts, mostly used for rack mounted installation shells of industrial control and network equipment.
