The IP68 enclosures except size 44.27 are made of corrosion-proof foundry grade aluminum alloy and they are coated with oven-cured thermosetting paint with epoxy power, which makes the enclosures highly resistant to scratch, shock, seawater, and chemicals. The IP68 enclosure series is larger than the standard enclosures, providing more space for easier cable management, and the walls are thicker to provide more mechanical robustness. However, the fixing points remain the same as those on the standard enclosure. The IP68 enclosures use two different locking systems, bayonets and screws, instead of the locking levers on the standard enclosure.
