Hoffman AL31 Latch Kit for Type 12 Enclosures

This Hoffman AL31 latch kit replaces the handle and latching rod on single-door Type 12 enclosures. It is designed for maintenance teams and panel builders who need to restore a secure, water-tight seal on existing Hoffman cabinets. The kit includes all necessary mounting hardware for a complete repair.

Quarter-turn operation with drilled-door requirement

Each latch requires a dedicated hole punched or drilled in the door, so the enclosure must be modified before installation. The quarter-turn mechanism opens or closes with a 90-degree rotation, providing fast access while the internal O-ring and external gasket maintain a dust-tight and water-tight barrier. This kit does not fit Concept or Proline enclosure lines.

Zinc-plated steel construction for corrosion

The latch components are manufactured from steel with a plated finish to withstand industrial environments. This specific material choice determines whether the kit will endure the humidity, wash-down chemicals or outdoor exposure common in NEMA 4 and 12 applications. Buyers needing stainless steel or non-metallic latches for harsher chemical exposure should look elsewhere.
