WL9-4318 Engineering PP Hardware Tool Case

The outer shell is 432 x 240 x 186 mm and the internal cavity is 407 x 187 x 178 mm. Externally the case occupies 432 x 240 mm while the usable floor inside is 407 x 187 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 407 x 187 mm floor with 178 mm of inner height is the long narrow deep body of the range: it occupies only 432 x 240 mm yet takes long-handled tools and slim bars standing up, trading floor area for height.

The lid adds 38 mm of internal depth and the base adds 140 mm, giving 178 mm of combined inner height. With 140 mm in the base and only 38 mm in the lid, upright contents get a long supporting wall and resist tipping in transit; the price is little space on the lid side, so parts with pronounced raised fittings need clearance planned separately.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. Long-handled tools travel between site and store, and the sealed cavity keeps grit and damp out, which also cuts the chance of metal parts rusting. 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 WL9-4318 is hardware tool cases, under code 912. The long narrow 407 x 187 x 178 mm cavity suits long-handled hand tools, pry bars, wrench sets and slim accessories as a group, and 178 mm of inner height lets them stand rather than lie diagonally. A 3 mm wall and a 1970 g weight fit vehicle and site transport, and the exported specification lists a handle height of 82 mm.

The cavities are identical at 407 x 187 x 178 mm, the wall is 3 mm on both, and the lid and base depths match at 38 mm and 140 mm. Two differences are on record: outside height is 186 mm against 188 mm, and unit weight is 1970 g against 1587 g, a gap of 383 g. The exported specification also lists a handle height of 82 mm for WL9-4318, while WL9-4319 does not list that item. If the project is sensitive to carton weight, start from the 1587 g figure; if the handle and exterior configuration matter, confirm the actual build of each before committing.

The 82 mm handle height is a dimension listed separately in the exported specification for WL9-4318 and describes how far the handle stands above the body. In practice it means that when the case goes into a shelf gap, a drawer or an outer carton, 82 mm of vertical space has to be allowed for the handle, or the case will not sit in properly or the handle will be pressed. When working out overall height, take the 186 mm body height and this handle dimension together rather than calculating shelf spacing from the body alone. If cases are to be stacked, confirm first whether the handles bear on each other and add a divider layer where they do.
