Compact, wall-mount Type 3/3R enclosure keeps critical controls contained in a space-saving footprint, reducing panel depth and simplifying routing around equipment. This minimizes installation time and wiring complexity, improving overall project efficiency while protecting components from dust, moisture, and incidental contact. Application: ideal for small control panels on machine frames, switchgear rooms, or outdoor equipment housings in manufacturing or facilities management. Carbon steel, 16 gauge with ANSI 61 gray painted finish delivers durable, corrosion-resistant protection across indoor and outdoor environments. The robust construction extends service life, lowering maintenance costs and downtime. Application: suitable for control cabinets near conveyors, pumps, or HVAC systems. Rain hood, continuous piano hinge, and pull-drawn catch provide improved weather resistance and convenient access. Combined with a hinged cover, this reduces ingress paths and makes routine inspections faster. Application: outdoor applications where exposure to rain and dust is a concern. External mounting feet enable flexible wall installation with alignment tolerance and reduced fastening complexity. This helps installers position the enclosure around existing utilities and supports quick retrofits. Application: retrofit projects or new builds in tight spaces. Bottom knockouts and padlock provisioning support neat wiring entries and secure access. Certified to UL 50, CSA C22.2, and NEMA 3R standards, the enclosure helps meet regulatory requirements and facilitate inspections. Application: electrical control housings for panel boards and instrumentation in harsh environments.
