Product Features

This 19-inch rackmount enclosure cabinet is engineered for applications requiring both security and airflow, making it an exceptional choice for IT infrastructure, AV control, and industrial electronics housing. Built from cold rolled steel and finished in a matte black powder coating, it delivers ruggedness and professional aesthetics suited to demanding commercial and industrial environments. The cabinet conforms to a 4U height specification, offering generous internal space for equipment that requires rack-based installation.

The most distinctive feature is the lockable perforated front door, which combines physical security with effective passive ventilation. The door is fabricated with a pattern of precision-cut triangular holes that promote substantial airflow, allowing internal devices to stay cooler during operation. The built-in lock provides protection against unauthorized access, making the cabinet suitable for installations in shared or sensitive spaces such as server rooms or public venues.

Internally, the enclosure provides ample space for components such as routers, small servers, power supplies, patch panels, or data recorders. It can also be fitted with custom interior brackets or support rails, depending on project needs. The enclosure’s rack ears and side-mounting points ensure a stable fit within standard 19-inch rack frameworks. The box structure is reinforced with high-gauge steel and precisely machined joints, enabling strong load-bearing capacity and long-term shape retention under stress.

Cable access and component integration are made simple with optional rear or side porting solutions. Whether used in an IT network rack, AV rack, or control equipment bay, the cabinet allows for organized cabling, system separation, and efficient layout of thermal zones. It supports integration with external cooling systems, dust filters, or monitoring accessories. The enclosure is also compatible with front panel modules or display cutouts for I/O controls, screen windows, or ventilation grilles, making it a truly customizable solution.

Product structure

The base structure of the enclosure is crafted from high-quality cold rolled steel sheets, precision cut using CNC and laser technology for consistent dimensions and hole alignment. The chassis is reinforced with folded edges and welded internal seams that enhance the cabinet’s strength while reducing vibration or panel flex. All surfaces are powder-coated to prevent corrosion, rust, and wear, even in high-humidity or temperature-variable environments.

The front panel is a standout design element: a full-metal door that integrates a lock mechanism and high-density triangular perforations. These geometric cutouts ensure superior air throughput compared to traditional circular patterns, while also adding a modern aesthetic. The door is hinged for easy opening and closing, and it can be optionally equipped with gas struts or spring latches for high-frequency access points. The locking system is keyed and can be customized with different security grades based on client specifications.

The side panels of the cabinet include threaded holes for mounting onto rails or for attaching internal supports. These panels are reinforced for torsional stability and prevent frame distortion under weight. Optional soundproofing or insulation layers can be integrated into the sides for specialized environments, such as studio racks or outdoor telecom applications. Additional perforation or mesh can be incorporated for even greater airflow, depending on thermal management requirements.

Inside the enclosure, the design supports modular integration. Removable trays, subframes, or DIN rail components can be installed to fit the client’s system layout. Wiring management accessories such as grommeted cable holes, cable ties, and pass-through holes ensure clean, professional-grade installations. This versatility enables usage across multiple industries including security surveillance, embedded computing, scientific instrumentation, and telecommunications.
