Overview

The Hammond Manufacturing N4X Wallmount Enclosure (SKU PJ20168RHW) delivers rugged, corrosion-resistant protection for industrial electronics and controls. Constructed from durable fiberglass, this NEMA 4X-rated enclosure resists water, dust, and chemical exposure—ideal for harsh environments like chemical plants, food processing facilities, and outdoor installations. Measuring 20.00 inches wide, 16.00 inches high, and 8.13 inches deep, it provides 2,580 cubic inches of internal volume for housing PLCs, instrumentation, or power distribution components. The non-conductive fiberglass material offers excellent impact resistance while eliminating grounding concerns. Wallmount design simplifies installation with pre-drilled holes and standard mounting hardware, optimizing vertical space in control rooms or equipment bays. Manufactured in the USA to meet industrial standards, this enclosure combines long-term reliability with ease of maintenance. Fiberglass construction ensures no rust or corrosion over time, reducing lifecycle costs compared to steel alternatives in corrosive environments.
