Steel Boxes

Steel boxes provide enclosed locations for electrical components, wiring connections, controls, and instrumentation. Common commercial uses include surface-mounted electrical installations, junction and pull box layouts, wall-mounted control housings, larger panel arrangements, and floor-mounted equipment enclosures where organized access is needed.

Helpful Buying Guide

Choose a Steel Box for Your Electrical Installation

Steel boxes in this category range from compact surface-mount enclosures and pull boxes to stainless steel Type 4X enclosures and large two-door floor-standing cabinets. Compare the intended enclosure type, mounting arrangement, available interior space, access style, closure features, and material construction to match the box to your component layout and service needs.

Use Cases

House components, connections, and controls

Use steel boxes to create an enclosed location for electrical components, wiring connections, controls, instrumentation, motor starters, drives, contactors, and PLCs. Pull boxes and junction boxes support wiring layouts, while larger cabinets accommodate more complex mounting arrangements.

How to Choose

Start with mounting, size, and access

Choose between surface-mount, wall-mount, and floor-standing configurations. Confirm the enclosure dimensions and consider whether a landscape layout, interior track, mounting channels, or panel mounting provisions fit the installation. Then select a hinged door, lift-off cover, screw cover, or two-door design based on access needs.

Applications

Match the box to the installation layout

Compact NEMA 1 enclosures suit contained electrical-component installations. Junction and pull boxes provide access to wiring connections. Stainless steel and gasketed enclosures offer protected component placement, while floor-standing two-door enclosures provide a broad opening for panel installation and removal.

Additional Information

Review closure and installation details

Available details include multiple knockouts, welded seams, gaskets, screw clamps, three-point latches, continuous hinges, grounding provisions, mounting hardware, and cover or door bonding provisions. Some enclosures also include tracks, mounting brackets, interior channels, or hardware for panel mounting.

NEMA 1Enclosure option

Available on steel enclosures for NEMA 1 requirements.

Type 4XConfiguration

Represented in stainless steel hinged and continuous-hinge enclosure designs.

180°Door access

Available on several hinged enclosure models for broad interior access.

2 doorsLarge enclosure access

Available on a floor-standing steel enclosure with a centerpost-free opening.

Planning Guide

Plan the right fit before choosing

Plan the enclosure layout

Select a box that supports the equipment inside

Begin with the components and wiring that need to be housed. Smaller surface-mount enclosures include integrated tracks, while other models offer interior mounting channels, full-width mounting brackets, or provisions for optional panels. For wider component arrangements, a landscape enclosure provides mounting space across the enclosure width. For larger panel layouts, consider a two-door enclosure with a centerpost-free opening.

  • Compare enclosure dimensions with the required component layout.
  • Look for tracks, channels, brackets, or panel mounting provisions as needed.
  • Consider a pull box or junction box for wiring connections and access.
  • Choose a floor-standing enclosure when elevated access beneath the unit is useful for cleaning.
Choose material and enclosure configuration

Compare steel and stainless steel options

The category includes 18-gauge steel enclosures, gray steel boxes, and stainless steel enclosure designs. NEMA 1 enclosures provide an option for NEMA 1 requirements. Type 4 and Type 4X configurations are represented by models with welded construction, gaskets, and secured closures. Stainless steel options include Type 304 and Type 316L construction.

  • Choose NEMA 1 models for projects requiring a NEMA 1 enclosure option.
  • Consider Type 4 or Type 4X configurations where the project calls for those enclosure types.
  • Compare gray steel construction with Type 304 or Type 316L stainless steel construction.
  • Review welded seams, formed flanges, and gasket details for the enclosure design.
Match access and closure to service work

Make routine access more practical

Access styles vary by enclosure. Hinged and continuous-hinge doors can open 180 degrees for broad interior access. Screw covers and lift-off covers provide another approach, with a retaining chain on one lift-off cover design to keep the cover attached during service. Closure options include external screw clamps, three-sided stainless steel clamps, quarter-turn latches, and three-point key-lock latches.

  • Choose a hinged door for repeatable access to enclosed components.
  • Consider continuous hinges for support along the door length.
  • Select a lift-off or screw cover where that access style fits the installation.
  • Check for grounding hardware, grounding studs, and door or cover bonding provisions.
