WL9-5419 PP/ABS Medical Equipment Case

The outer shell is 540 x 445 x 190 mm and the internal cavity is 525 x 400 x 170 mm. Externally the case occupies 540 x 445 mm while the usable floor inside is 525 x 400 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 525 x 400 mm floor with 170 mm of inner height, split 85 mm to the lid and 85 mm to the base — a rare symmetric layout in the 9 Series — and the same body is offered in both PP and ABS versions.

The lid adds 85 mm of internal depth and the base adds 85 mm, giving 170 mm of combined inner height. At 85 mm each, lid and base both work as usable trays, so contents can be laid in either half, and a symmetric split also lets a two-part lining be made interchangeable rather than top and bottom specific.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. The sealing face sits at the middle of a symmetric body, so the closing load is spread evenly, and the cavity protects against dust and moisture much as the other bodies in the series do. 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 WL9-5419 is medical equipment cases, under code 2113. Its symmetric 525 x 400 x 170 mm cavity suits flat equipment, accessory sets and instrument panels arranged in layers, with either half able to hold parts. Where carton weight matters choose the PP version; where surface hardness and finish matter choose ABS. Both share the same outside size and cavity.

Both versions share the 540 x 445 x 190 mm outside size, the 525 x 400 x 170 mm cavity, an 85 mm lid and an 85 mm base, and a 5 mm wall. Only the material and weight differ: 3600 g in ABS against 3110 g in PP, a gap of 490 g. Where the project has a hard ceiling on carton weight, freight or manual handling, work from the PP figure. Where surface hardness and finish matter more, take ABS. Because the outside is identical, one carton and pallet plan covers both, and only the unit weight of the version ordered needs confirming for pricing and freight.

WL9-5419 is poly-bagged individually and packed 1 per carton measuring 550 x 485 x 755 mm, so it is one case to a box. The carton tracks the 540 x 445 x 190 mm body plus cushioning, and the 755 mm long side is well above the body height, which shows how much cushioning allowance the carton carries vertically. Per unit that means 3600 g in ABS or 3110 g in PP before the carton, so gross weight runs a little higher. Because each carton holds one case, plan container loading in advance so empty space does not push freight up; carton breakdowns and loading plans can be confirmed with the order.
