Standard for
The car model for which the boot is intended.
Products positioned as standard products can be produced both for a specific car model and for a specific line. Anyway, such a boot is better suited for a car than a universal model, because. its fastenings and shape, by definition, are optimized for a specific “seat”. On the other hand, finding a regular version is usually somewhat more difficult than a universal one, and such boots are not available for some brands at all.
Nowadays, on the market you can find, in particular, regular boots for cars from such manufacturers:
Audi,
BMW,
Chevrolet,
Citroen,
Daewoo,
Ford,
Honda,
Hyundai,
KIA,
Lada,
Mazda,
Mercedes-Benz,
Mitsubishi,
Nissan,
Opel,
Peugeot,
Renault,
Seat,
Skoda,
Subaru,
Suzuki,
SsangYong,
Toyota,
UAZ,
Volkswagen.
Load capacity
The maximum weight that is allowed to be carried on the boot.
It is definitely not worth exceeding this parameter — even if the structure does not break immediately, this can happen at any time due to off-design loads. And ideally, you should have some margin for carrying capacity — this will give an additional guarantee in case of emergency situations (like hitting a wheel in a hole at speed).
Also note that the weight of the intended load must be supported not only by the boot itself, but also by the crossbars on which it is installed (if this installation option is used, see above). Moreover, the weight of both the cargo and the boot falls on the crossbars, which requires an even greater margin for load for them.
As for specific carrying capacity indicators, in general, the indicator
up to 50 kg is considered relatively low,
51 – 75 kg — average,
76 – 100 kg — above average, and in the most "heavy" models, the permissible load weight
exceeds 100 kg.
Crossbars length
The length of the crossbars (see "Type") included in the scope of supply. If the slats are of different lengths, both sizes are specified in this paragraph; if one number is indicated here, this means that the size of both crossbars is the same.
Anyway, the length of the crossbars must be no less than the distance between the attachment points of each of them (for example, between the left and right railing) — otherwise the size of the rail is simply not enough to block the space from one point to another. But the margin for this indicator is quite acceptable: most models have the ability to adjust the exact distance between the mounts (at least within a few centimeters). However, for a full guarantee, the range of such adjustment and compatibility with a specific car is still desirable to clarify separately.
