Overview

The ABB 458 Square Box Surface Cover (SKU: 458) is a galvanized steel solution engineered for industrial electrical applications requiring robust, corrosion-resistant protection. This 4-inch square cover features a 1/2-inch raised design for proper clearance and a 6.5 cubic inch capacity, making it ideal for housing one 4-wire twist lock device with a 1.594-inch opening. Constructed from durable galvanized steel, the cover ensures long-term performance in harsh environments, including industrial facilities, commercial buildings, and outdoor installations where exposure to moisture or chemicals is a concern. The 1/4-inch diameter hole opening is precision-engineered to accommodate standard twist lock devices, providing a secure fit without the need for additional modifications. Unlike generic plastic covers, the ABB 458’s steel construction resists deformation, cracking, or UV degradation, reducing maintenance costs and downtime.
