The ADP12012LR5 is a replacement left door manufactured by nVent HOFFMAN. It is designed for use with MAD series enclosures measuring 1200mm in height and 1200mm in width. The unit features a mild steel construction finished in RAL7035 color. It includes a standard locking system for secure access.
Verify that the target enclosure matches the MAD series dimensions of 1200mm height by 1200mm width before procurement. Confirm that the required side is the left door, as this part is not interchangeable with right-door variants. Ensure the existing mounting hardware is compatible with the standard locking system included with this replacement unit to avoid installation issues.
Select this component only when replacing a left door on a 1200x1200mm MAD enclosure. Do not use for right-side applications. Verify the need for a standard locking system; if specialized locking is required, other variants may be necessary. Ensure the RAL7035 finish meets aesthetic requirements for the installation environment.
This part belongs to the nVent HOFFMAN accessory line for industrial enclosures. It serves as a spare or replacement component rather than a standalone enclosure. It is intended for maintenance purposes to restore functionality to existing MAD series cabinets without replacing the entire structure.
This is a direct replacement for the left door of MAD 1200H x 1200mmW enclosures. No alternative part numbers are documented for this specific configuration.
