Find the right protective case

Enter the dimensions of the equipment you have to protect. The engine filters all 155 standard shells on internal length, width and height against your envelope plus clearance, ranks them by unused volume, slack, empty mass and required features, and returns three recommendations — or tells you honestly that a custom route is the right answer.

Method

The engine, in six steps

How the ranking works

01

Dimension filter

Internal length, width and height must each exceed your envelope plus clearance. Anything short is excluded outright, not penalised.

02

Weight filter

Packed mass plus empty case mass over 25 kg without wheels is excluded, because a case you cannot move is not a solution.

03

Feature filter

Wheels, sealing option, lock, carry handle and custom foam are hard constraints when you tick them, not scoring bonuses.

04

Application filter

If you name a sector, models whose family is not used in that sector are dropped and those that are get a weighting. This is what stops a dimension match producing a clinically wrong suggestion.

05

Fit score

The dominant term is unused internal volume, then evenness of slack across the three axes, then empty mass against your packed mass. A shell twice the size you need costs freight and mass for every year of its life.

06

Three recommendations

Best fit, a roomier option, and an alternative structure, so your purchasing review has something to compare rather than a single answer to argue with.

07

Same engine as an API

The ranking is a standalone module, not markup. /api/case-match/ documents the request and response shape so a mobile app, a CRM, an AI agent or a partner portal can call the identical algorithm against the identical data.

What a fit score is

A fit score ranks models against your requirement. It is not a quality rating, and a case scoring 78 for one kit may be the wrong case for another. Nothing in this engine ranks products publicly.

When nothing fits

If no standard shell clears your envelope, the engine says so and routes you to the custom path: a bespoke interior on an existing mould at 45 days, or a new mould at 125 days with a stated MOQ. We will not stretch a dimension to make a sale.

Data source

All 155 records come from the same product database that publishes every product page and datasheet on this site. One source of truth, so the tool cannot disagree with the catalogue.

Limits of this tool

The engine matches geometry. It does not know your centre of gravity, your connector layout, or whether a protruding handle needs a cut-out. Treat a match as a shortlist, and confirm with a sample before production.
