Overview

The nVent AL31 Latch Kit (SKU: AL31) is a quarter-turn (90-degree) latch designed for Type 4 and Type 12 enclosures with external screw clamps. Engineered for rapid access and secure sealing, the AL31 ensures a reliable watertight and dust-tight enclosure by integrating an internal O-ring and an external gasket. The slotted insert design provides broad compatibility with various enclosure systems, while the die-cast zinc construction with a chrome finish delivers corrosion resistance and durability. Installation is simplified, requiring only a single punched or drilled hole per latch on the enclosure door. For enhanced security, the AL31 supports operation with a square or triangular key, making it ideal for tamper-resistant applications. This latch kit is a critical component for industrial environments where environmental sealing and equipment protection are essential.
