WL9-6922 Protective Case

The outer shell is 685 x 500 x 220 mm and the internal cavity is 600 x 420 x 200 mm. Externally the case occupies 685 x 500 mm while the usable floor inside is 600 x 420 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. At 600 x 420 mm this is the largest usable floor exported in the 9 Series, paired with 200 mm of inner height so a complete unit and its accessories can be laid out in layers; a 6140 g weight means two people or a trolley to move it.

That depends on the measured height of the equipment, not on the outside height of the case. The usable inner height here is 200 mm, and the measurement should include feet, top connectors, knobs and cable plugs, since these raised parts are the usual cause of an over-height load. If little clearance remains once the unit is in, either stow the accessories separately or move to a deeper body; if the unit fills only about half the height, the spare room is better used for a layered lining that holds the main unit and its accessories apart in transit. Lining thickness also comes out of the same 200 mm, which is worth settling at the design stage.

The shell uses a sealed closure and provides an IP67 waterproof and dustproof rating. When a complete unit and its cables travel in one case, the sealed cavity limits dust reaching the connectors and keeps moisture from 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 category listed for WL9-6922 is medical equipment cases. The 600 x 420 x 200 mm cavity suits a complete medical unit, a full inspection instrument set, and accessories and cables stowed in layers in the same case, which cuts assembly time on site. PP and a 6140 g unit weight mark it as a station-to-station case rather than a carry case, suited to movement between departments, between sites, or to exhibitions.

On the exported inner figures, WL9-6922 offers a 600 x 420 mm floor against 500 x 340 mm on WL9-5723, which is 100 mm more one way and 80 mm more the other. Inner height runs the other way: 200 mm against 211 mm, an 11 mm difference. Unit weight is 6140 g against 4680 g. In other words, WL9-6922 buys you floor area at the cost of 1460 g of extra weight and slightly less height, so settle the footprint of the load first and then check whether the heavier case still suits how it will be moved.
