20 × 20 × 15 cm

The size 20 × 20 × 15 cm means that the item has a length of 20 cm, a width of 20 cm and a height of 15 cm. This compact cubic shape is suitable for installation in small body cavities, under instrument panels or in confined engine‑compartment spaces. When selecting a part or accessory, you should ensure that the available space is not smaller than the specified dimensions, and also consider possible mounting tolerances (±1‑2 cm). If better access to cables or hoses is required, choose products with similar or slightly smaller dimensions to avoid collisions.
