WL9-5321 Engineering PP Medical Equipment Case

The outer shell is 525 x 434 x 214 mm and the internal cavity is 481 x 373 x 192 mm. Externally the case occupies 525 x 434 mm while the usable floor inside is 481 x 373 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 481 x 373 mm floor with 192 mm of inner height, and at 5.8 mm the thickest wall in the exported 9 Series; a 4810 g unit weight marks it for heavy-duty circulation rather than carrying by hand.

The lid adds 43 mm of internal depth and the base adds 149 mm, giving 192 mm of combined inner height. A 43 mm lid over a 149 mm base puts the depth in the body and gives upright equipment a 149 mm supporting wall, while the lid side leaves some room but should not carry the main load.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. Heavy-duty cases often sit at the bottom of a stack, and the sealed cavity keeps the contents clean even under that load by holding dust and moisture out of the equipment. 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 category for WL9-5321 is medical equipment cases, under code 828. The 481 x 373 x 192 mm cavity and 5.8 mm wall suit heavier mid-size equipment shipped complete, long-term circulation and full-pallet stacking. A 4810 g unit weight means two people or handling equipment, which fits movement between sites or across a campus. Where the case is opened often as well, divide the lining so the parts in daily use sit together on one side and less time is lost searching.

WL9-5321 is poly-bagged individually and packed 3 per carton measuring 530 x 440 x 635 mm. Only three fit because each unit measures 525 x 434 x 214 mm and weighs 4810 g, so the carton is close to a simple multiple of the single-unit footprint. Gross weight for three units lands in the mid-teens, still within normal manual handling, but the carton is bulky, so confirm the stack height stays inside what the body can take. Carton breakdowns, pallet plans and container loading layouts can be supplied with the order.
