Custom Electrical Enclosures Manufactured in Texas for Industrial Applications

Q: Can custom enclosures be built for outdoor environments?

Yes. Enclosures can be designed for various NEMA ratings including NEMA 3R, NEMA 4 and NEMA 4X applications.

Every industrial project eventually encounters a situation where a standard enclosure simply does not work. The equipment may be too large, the environment too harsh, the footprint too restrictive or the application too specialized for an off-the-shelf solution. When that happens, custom enclosure manufacturing becomes critical.

Larson Electronics designs and manufactures custom electrical enclosures in Texas for industrial, utility, municipal, energy, oil and gas, marine, water treatment, manufacturing and infrastructure projects. From compact junction boxes to large walk-in electrical enclosures, our team supports custom fabrication projects that require engineering flexibility, durable construction and responsive manufacturing.

With in-house fabrication capabilities, engineering support and domestic manufacturing, Larson Electronics helps customers solve enclosure challenges quickly and efficiently while maintaining control over project schedules and specifications.

Standard Enclosures Do Not Fit Every Application

Industrial facilities are filled with unique equipment combinations, installation requirements and environmental challenges. While standard enclosures work well for many projects, they often create limitations when engineers must accommodate specialized equipment or unusual site conditions.

Common reasons customers request custom enclosures include:

Non-standard equipment dimensions
Large power distribution systems
Transformer and switchgear integration
Space constraints
Outdoor exposure
Corrosive environments
Hazardous locations
Special cable entry requirements
Custom mounting arrangements
Equipment upgrades within existing footprints

Custom fabrication allows the enclosure to be designed around the equipment instead of forcing the equipment to fit inside a standard cabinet.

Larson Electronics Manufactures Custom Enclosures in Texas

Larson Electronics supports projects ranging from single custom cabinets to large-scale production runs.

Our Texas manufacturing facilities allow us to fabricate enclosures designed specifically for customer requirements, including:

Control panel enclosures
Power distribution enclosures
Switchgear enclosures
Transformer enclosures
Industrial control cabinets
Operator interface stations
Outdoor equipment enclosures
Marine and coastal enclosures
Hazardous location enclosures
Custom electrical cabinets

Because fabrication occurs domestically, customers gain direct access to engineering and production teams throughout the design and manufacturing process.

Multiple Materials Are Available to Match Project Requirements

Material selection is one of the most important decisions in enclosure design. Environmental conditions, corrosion exposure, washdown requirements, structural demands and project specifications all influence material selection.

Material	Typical Applications	Key Advantages
Carbon Steel	Industrial facilities, power systems and protected environments	Strength, versatility and cost effectiveness
Aluminum	Weight-sensitive and outdoor applications	Lightweight and corrosion resistant
304 Stainless Steel	Washdown and industrial environments	Excellent corrosion resistance
316 Stainless Steel	Marine and highly corrosive environments	Enhanced resistance to chloride exposure and saltwater conditions

Material selection is often driven by the operational environment, expected service life and customer specification requirements.

NEMA Ratings Help Match the Enclosure to the Environment

Environmental protection is often one of the primary drivers behind custom enclosure projects.

Larson Electronics supports enclosure designs for a wide range of NEMA configurations, including:

NEMA 1
NEMA 3R
NEMA 4
NEMA 4X
NEMA 12
Custom environmental protection requirements

NEMA 4X enclosures are particularly common in marine, wastewater, food processing, chemical processing and outdoor industrial applications where corrosion resistance and weather protection are critical.

Large Enclosures Support Complex Electrical Systems

Many industrial projects require more than a simple electrical cabinet.

Large custom enclosures may be designed to house:

Switchgear assemblies
Motor control systems
Power distribution equipment
Industrial control systems
Automation equipment
Communication systems
Custom transformer assemblies
Utility infrastructure equipment

Large-format fabrication capabilities allow Larson Electronics to support projects involving substantial equipment loads, custom layouts and specialized installation requirements.

Hazardous Location Experience Supports Complex Industrial Projects

Larson Electronics has decades of experience supporting hazardous location applications.

Many enclosure projects involve environments where flammable gases, vapors, dusts or fibers may be present.

Applications may include:

Oil and gas facilities
Refineries
Chemical processing plants
Fuel storage terminals
Battery facilities
Marine fuel operations
Manufacturing facilities
Wastewater treatment plants

Custom enclosure projects can be designed around the requirements of the installation while supporting customer specifications and project documentation requirements.

Engineering Support Simplifies Complex Projects

Many enclosure projects begin with a problem rather than a finished design.

Customers often know what equipment must be protected but have not yet finalized enclosure dimensions, mounting requirements or internal layouts.

Larson Electronics works with engineers, contractors, OEMs, utilities and facility managers to develop enclosure solutions that address:

Equipment layout
Cable routing
Access requirements
Thermal management
Environmental protection
Structural requirements
Maintenance accessibility
Future expansion requirements

Engineering collaboration early in the project often reduces installation challenges later.

Texas Manufacturing Supports Faster Delivery and Greater Flexibility

Global supply chain disruptions have demonstrated the value of domestic manufacturing.

Larson Electronics manufactures in Texas, centrally located to efficiently support projects throughout North America.

Benefits of domestic production include:

Faster communication
Reduced shipping complexity
Greater design flexibility
Improved schedule visibility
Rapid engineering changes
Support for custom fabrication projects

For many industrial customers, the ability to work directly with a U.S.-based manufacturer can significantly reduce project risk.

Custom Enclosures Help Solve Unique Industrial Challenges

Every facility has unique operational requirements. Whether the project involves protecting sensitive electronics, housing power distribution equipment, supporting a hazardous location installation or accommodating unusual dimensions, custom enclosure manufacturing provides flexibility that standard products often cannot match.

By combining engineering support, fabrication expertise and Texas-based manufacturing, Larson Electronics helps customers develop enclosure solutions tailored to the needs of the application.
