Overview

The nVent APO A12 Extension Collar (SKU: A12-EXT2424LG) adds 2.36 inches of vertical depth to nVent APO enclosures, enabling deeper mounting of internal components. Constructed from fiberglass-reinforced polyester (FRP), this light gray collar delivers corrosion resistance and durability for harsh industrial environments, including utilities, telecommunications, and manufacturing. Its dimensions of 23.74 x 24.74 x 2.36 inches (598 x 628 x 60 mm) ensure compatibility with nVent APO enclosure systems while maintaining NEMA Type 1 and IP30 ratings. The extension collar supports expanded internal layouts for larger electrical and electronic equipment, cables, and accessories, making it ideal for advanced control systems, networking hardware, and power distribution units. Installation is straightforward, requiring secure bolting between the enclosure base and cover without compromising protective capabilities. The light gray finish reduces heat absorption compared to darker colors, enhancing performance in outdoor or high-temperature applications.
