1. Overview

Boxes, enclosures, and racks are critical components for housing, protecting, and organizing electronic, electrical, and mechanical systems. Boxes provide physical protection for individual devices, enclosures offer environmental and safety shielding, while racks standardize mounting and space utilization. These solutions ensure operational reliability, thermal management, and efficient system integration across industries.
