WL9-5726 PP Military Equipment Case

The outer shell is 576 x 363 x 257 mm and the internal cavity is 520 x 296 x 210 mm. Externally the case occupies 576 x 363 mm while the usable floor inside is 520 x 296 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 520 x 296 mm floor with 210 mm of inner height and a 385 mm trolley handle listed in the exported specification, the wheeled long body of the 9 Series that one person can pull; the 5600 g weight comes mainly from the trolley and the shell structure.

The lid adds 55 mm of internal depth and the base adds 155 mm, giving 210 mm of combined inner height. A 55 mm lid over a 155 mm base leaves headroom on top while keeping the depth in the body, so long items standing upright get a 155 mm supporting wall and stay steadier when the case is pulled on its trolley.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. A wheeled case is dragged between sites and outdoors, and the sealed cavity keeps dust and rain from entering at the joint, protecting the equipment inside. 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 WL9-5726 is military equipment cases, under code 8112, meaning whole-case transport of field and site equipment. The 520 x 296 x 210 mm cavity suits long items, complete field accessory sets and instrument combinations shipped together, and the 385 mm trolley handle lets one person pull it. A 5600 g weight, most of it in the trolley, fits work where the case moves often but is not carried far at a time.

The 385 mm figure is listed separately in the exported specification and describes how far the handle stands above the body when extended. In practice it sets both the towing posture and the storage envelope: the grip sits above the body, so whether it feels comfortable depends on the user's height and is worth judging against that figure, and when the case is stored or loaded the handle is part of the overall footprint, so planning on the 576 x 363 x 257 mm body alone is not enough. If the case goes into an outer carton or a shelf, confirm whether the handle retracts or stays proud of the shell before fixing the clearance, and ask the factory for the folded outline dimensions.
