Square Box industrial enclosure manufacturing

Data Center Power Enclosure Assemblies

Data center power auxiliary enclosure with terminal blocks and monitoring wiring

Custom enclosures, mounting plates and pre-wired subassemblies for UPS, PDU, RPP, switchgear, generator, cooling and monitoring equipment.

Why data center power equipment needs faster enclosure assemblies

Data center power projects compress engineering, procurement and installation schedules. Component-ready enclosure assemblies help move repeat mounting, labeling and low-voltage wiring tasks into a controlled factory workflow before equipment reaches the job site.

What we build

  • Custom sheet metal power enclosures
  • Mounting plates and back panels
  • Component-ready subassemblies

Low-voltage pre-wiring support

Low-voltage pre-wiring support is available to customer drawings, terminal schedules and customer-approved BOMs. Square Box can support labels, wire duct routing, grounding points and component mounting when specifications are confirmed before production.

Component sourcing or installation support is based on customer-specified or customer-approved BOM items. Final listing, field acceptance and compliance depend on the complete project design and required testing.

Inspection photos before shipment

Inspection photos are provided for prototype orders before shipment and are available for batch production upon request.
