WL9-4822 Protective Case

The outer shell is 483 x 381 x 224 mm and the internal cavity is 460 x 330 x 210 mm. Externally the case occupies 483 x 381 mm while the usable floor inside is 460 x 330 mm, the difference coming from the wall section, the seal channel and the moulded closing geometry rather than measurement error. Size a load from the inner dimensions, never from the outside, because outside figures overstate capacity. A 460 x 330 mm floor with 210 mm of inner height covers both layouts: a mid-size main unit lies flat with room to spare, and a panel-faced instrument also stands upright, so one body handles two packing styles.

The lid adds 45 mm of internal depth and the base adds 165 mm, giving 210 mm of combined inner height. A 45 mm lid over a 165 mm base leaves some headroom on top while keeping most of the depth in the body, so upright equipment gets a 165 mm supporting wall and stays stable in transit.When judging whether a body suits your contents, read the base figure first, because it sets how tall an item can stand, while the lid figure decides how much headroom remains above it. Only the sum of the two is usable height, and when measuring a part, include handles, connectors and bosses, or the lid will press on it once closed.

The shell uses a sealed closure and provides an IP67 waterproof and dustproof rating. Mid-large cases usually carry equipment complete, and the sealed cavity limits dust reaching connectors and vents while reducing the chance of moisture condensing on metal parts in transit. 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 for WL9-4822 are precision instrument cases, hardware tool cases and medical equipment cases. The 460 x 330 x 210 mm cavity takes a mid-size instrument, a control module, a tool set and its cables in one case, and heavy items can travel low in the base with accessories layered above. At 2710 g one person can still move it short distances, while longer routes are better handled with a cart to avoid fatigue and knocks.

Yes. This model is supplied factory-direct from the Zhongshan plant of Kexin New Materials (Guangdong) Co., Ltd. for OEM and ODM wholesale, with routed and compartmented linings available. Divide the 460 x 330 x 210 mm cavity by load type: cut the pocket to the outline of equipment that lies flat and take the pocket depth from the 165 mm base side, or cushion above and below equipment that stands upright, remembering that only 45 mm is available in the lid. Where a main unit shares the case with cables and accessories, keep the heavy item low in the base and put the accessories above it or in shallow lid-side pockets, so the heavy part cannot press on them once closed.
