WL8-4820 Protective Case

The case measures 463*370*195 mm outside and 437*308*180 mm inside, with a 4.5 mm wall and an empty weight of 3273 g. That gives a usable floor of 437 by 308 mm and 180 mm of internal height, a tall option on this footprint, so equipment with handles or brackets and items that need to stand upright will fit. Leave a little clearance around each item, and send a drawing or photo if a part comes close to the 180 mm limit.

The body is injection moulded in engineering-grade polypropylene with a sealing structure, and the closed case is rated IP67 for water and dust protection. That covers rain, dusty workshops and short immersion, keeping equipment free of moisture and particles. We do not claim military standard certification for this model. The rating depends on the lid seating correctly on the gasket, so check the seal for ageing or trapped debris and avoid prolonged rain or immersion once it is damaged.

The body is engineering-grade polypropylene with a 4.5 mm wall, and the empty case weighs 3273 g. Engineering PP is chosen for better rigidity, impact resistance and dimensional stability under repeated handling, and the 4.5 mm wall helps a taller case hold its shape at a manageable weight. Ask our sales team for the specific grade and inspection documents before ordering. Clean with water or a mild detergent and a soft cloth.

A tall case invites heavier loading, so keep the total packed weight within a sensible range and avoid long-term overloading. Use both hands when carrying and keep the case level. The extra height is useful for stacking small parts or housing upright equipment, but too many stacked layers can shift in transit, so divide the cavity with compartmented foam. Send the size and quantity of each item and we will design an insert for the 437*308*180 mm cavity.
