QILIPSU Hinged Cover Stainless Steel Latch Junction Box with Inner Door 510x410x200mm, Universal IP67 Waterproof Electrical Box with Mounting Plate, ABS Plastic Grey (20"x16.1"x7.9" D)
We began stocking this enclosure because QUILISU makes a fantastic enclosure for the price if you need a backplane and the inner door.
Amazon also sells it, but they're constantly sold out. Shipping cost overseas mean big orders, and we needed to keep some on hand as well, so you benefit from this if you're here because Amazon is sold out!
