WL6-4618 Protective Case

The outer shell is 450 x 305 x 176 mm and the internal cavity is 430 x 290 x 165 mm. Externally the case occupies 450 x 305 mm of bench or shelf space while the usable floor inside is 430 x 290 mm, the difference coming from the wall section and the moulded closing geometry. Size a load from the inner dimensions, never from the outside, because outside figures overstate capacity. The 165 mm inner height is the maximum upright height available, and any lining you add reduces it further, so allow for that when the insert is designed.

This model uses an ABS shell with a 4.7 mm wall and a unit weight of 2775 g. The 4.7 mm wall and 2775 g weight match the 450 x 305 x 176 mm body, so it resists bulging when fully loaded and can be stacked. ABS takes up very little moisture and holds its dimensions at low temperature, which is why it is widely used for instrument and tool cases. The wall section drives compressive and impact behaviour, so how the case performs in transit and in stacks is largely set here, and the 2775 g unit weight is the figure to use for freight and pallet load calculations.

The shell uses a sealed closure and provides an IP67 waterproof and dustproof rating. A case used across several duties is opened often, so it is worth inspecting the rim regularly to keep the dust and water protection intact. The rating applies to the sealed cavity of the case itself, so if you store moisture-sensitive contents, pair it with desiccant or a humidity management accessory and check the sealing face for trapped debris every time you close the lid, since a single trapped fragment undermines the seal.

The factory usage categories listed for WL6-4618 are cigar humidors; precision instrument cases; knife cases. It suits operations that want a single case type shared across departments for storage and transport. With a 430 x 290 x 165 mm cavity and a unit weight of 2775 g it works best as fixed-station storage or a vehicle-transport case that needs protection from moisture, dust and knocks, rather than as a container left permanently outdoors.
