What APX Enclosures Inc does

APX Enclosures Inc is a U.S.-based custom manufacturer of NEMA-rated electrical enclosures, headquartered in Greencastle, Pennsylvania. Founded in 2001 as Tri-County Enclosures Inc. and rebranded in late 2003, the company specializes in NEMA 3R and 4X enclosures fabricated from aluminum, stainless steel, and carbon steel, with a UL 508A-certified manufacturing capability that allows it to apply the UL Listing label in-house. Its product portfolio spans standardized enclosure styles (double door, quad door, rack mount, pedestal, specline, single-door variants) and application-specific solutions for telecommunications, traffic control, EV charging, battery/generator storage, security/surveillance, server racks, control panels, and utilities. The company is part of APX Company, a five-entity integrated manufacturing platform (Enclosures, York Sheet Metal, Industrial Coatings, Mitchell Machine Shop, Precision Routing) operating across roughly 55,000 sq. ft. of manufacturing space equipped with CNC Amada Punch Press, Amada FJ lasers, press brakes, and welding cells.

The underlying technology centers on sheet metal fabrication with proprietary differentiators including a heat-resistant ceramic coating that reflects 95% of solar load, a nylon-roller three-point latching system for environmental sealing and vandal resistance, and closed-loop cooling architectures for harsh-environment deployments. APX sells primarily through a direct, sales-led motion: quote-based custom projects are routed through website contact forms and phone inquiries, with Project Engineers assigned from prototype through production, and some deals operating on multi-year contract cadence. Customer mix spans telecom, transportation/infrastructure (described as primary), battery/energy storage, EV infrastructure, security, utilities, data centers, and industrial controls, with no named end-customer logos publicly disclosed. The company is a veteran-owned small business with no external institutional funding or venture capital recorded in available materials, and reports revenue is not publicly disclosed.

Scale indicators5 records

Recent moves9 records

Expansion highlights5 records

Emerging players

• Polycase: Polycase is a US manufacturer of plastic and metal electronic enclosures serving industrial, instrumentation, and electronics customers. Comparable to APX in enclosure product category and US custom manufacturing, but typically smaller-scale electronics enclosures rather than full NEMA 3R/4X outdoor infrastructure cabinets.

Direct peers

• Hammond Manufacturing: Hammond Manufacturing is a Canadian manufacturer specializing in NEMA-rated electrical enclosures, racks, cabinets, and climate-control accessories. Closely comparable to APX in NEMA 3R/4X product focus, custom-modification capability, and target verticals (industrial, telecom, utilities); competes head-to-head in the same enclosure specifications APX serves.
• Stahlin Enclosures: Stahlin (a Robroy Industries brand) manufactures NEMA 4X fiberglass and polycarbonate enclosures for harsh-environment and corrosive applications. Directly comparable to APX in NEMA 4X specialty focus, materials-driven differentiation, and overlap with water/wastewater and chemical end markets.
• Integra Enclosures: Integra Enclosures is a US manufacturer of polycarbonate and metal NEMA 4X enclosures focused on harsh-environment and corrosive applications. Comparable to APX in NEMA 4X specialization and US manufacturing footprint, though with a narrower materials focus (polycarbonate vs. metal).
• Saginaw Control & Engineering: Saginaw Control & Engineering is a US manufacturer of NEMA-rated electrical enclosures, consoles, and custom metal fabrication serving industrial control, telecom, and infrastructure customers. Highly comparable to APX as a similarly sized US custom enclosure specialist with UL-listed products and modification services.

Broad incumbents

• Rittal: Rittal is a global German enclosure manufacturer with a broad NEMA/IEC enclosure portfolio, climate-control integration, and standard/modular product lines. Highly comparable to APX in product category (NEMA enclosures, climate control, custom modifications) and customer verticals, but with much larger scale, automation, and international footprint.
• Hubbell (Raco / TayMac / Bell): Hubbell's Raco and TayMac brands produce electrical enclosures, boxes, and wiring devices for commercial, industrial, and residential markets. Comparable to APX in enclosure category and electrical-distribution channel positioning, but operates as a diversified public electrical-products platform with significantly broader product breadth.
• Eaton (B-Line, Hoffman): Eaton is a global power-management company with enclosure product lines (B-Line, Crouse-Hinds, others) serving industrial, utility, and infrastructure customers. Comparable to APX in NEMA enclosure category and infrastructure customer base, but operates as a multi-billion-dollar diversified electrical equipment platform.
• nVent (Hoffman Enclosures): nVent's Hoffman brand is a market-leading manufacturer of NEMA-rated electrical enclosures for industrial, infrastructure, and data-center applications. Comparable to APX because it sells UL-listed NEMA 3R/4X enclosures into overlapping verticals (telecom, traffic, utilities), but operates at vastly greater scale with global distribution.
• Schneider Electric (Square D / Spacial): Schneider Electric offers industrial enclosures under the Spacial and Thalassa lines plus Square D control panels, competing directly with APX in NEMA enclosures for industrial control and infrastructure applications. Comparable product category and customer overlap, but at global enterprise scale.
