Open boot. The simplest kind of boot, which is a platform — most often not solid, but in the form of a set of parallel rails. Such a platform is installed on the crossbars (see "Installation"), and the transported cargo is fixed on it. The main advantage of open boots is the absence of restrictions on the height of transported items: it can be almost any (within reasonable limits, of course), the main thing is that the load capacity of the structure is enough. On the other hand, the load must be securely fastened — otherwise, at the slightest shock, it may simply fall out of the boot; and there is no talk of aerodynamics. In addition, the items transported in this way are absolutely not protected from external conditions. Because of this, when transporting delicate cargo, you will either have to choose favorable weather, or provide additional protection from rain, dust, etc. on their own.

Boxing. A closed type of luggage carriers are containers that are usually installed on the crossbars on the roof. Most of the boxes are aerodynamically shaped (hence the variant of the name — "aeroboxes"), which reduces additional fuel consumption and noise levels. In addition, the closed design protects the contents from adverse external conditions, and also ensures that they do not fall out of the boot. Due to this, it is only necessary to secure the cargo in the box so that it does not hang around the cont
...ainer (and with a dense load, the problem is solved by itself). The main disadvantage of such models is the limited volume, which does not allow transporting large items.
— Cross bars. Strictly speaking, the crossbars are not luggage carriers, but additional devices for installing various luggage carriers and mounts. They are rails that are placed, as the name implies, across the roof of the car — and additional devices can be mounted on these rails. The standard scope of supply includes two crossbars with fasteners; in some cases (in particular, when mounting on roof rails, see below), the distance between them can be adjusted, which makes it possible to adjust the design to different models of boots.
— Mount for skis / boards. A device for carrying skis or snowboards, usually on the roof of a car. In most cases, it has the form of paired mounts mounted on the front and rear cross members; each board or pair of skis is fixed at two points. It is more convenient to use specialized mounts for transporting such equipment than general-purpose boots.
— Bicycle rack. A special device that allows you to transport a bicycle (or several bicycles) without dismantling or folding. There are two main types of such mounts. The first option involves installation on the roof, on the crossbars, and the bike in this design is placed vertically along the car body. The second option is designed for mounting at the rear (on the door, tow bar or wheel) and for the transverse position of the load. Anyway, special mounts greatly simplify the transportation of bicycles, and the two-wheeled vehicles themselves are transported in working position and, after being removed from the car, can be used almost immediately, without special training.
— Mounting for boats. Devices for transporting boats — most often kayaks and canoes. Typically, such mounts are a pair of supports mounted on crossbars and shaped to match the bottom; the boat is placed on these stands and fixed with straps. There are other design options — for example, mounts for two kayaks, which involve the placement of boats on their side, relying on the side.
— Mount for surfing. Mounting for boards used in surfing. Some of these racks can also be used for other similar devices such as SUP boards, but this possibility should be specified separately.
— Mount for windsurfing. Fastening for boards used in windsurfing (surfing with a sail). Such boards are different from surfboards, respectively, and racks are different — they are designed for a larger size of the board, and also have a mount for the mast. In addition, such racks in most cases can be used for SUP boards (and some even have the word "SUP" in the name).
— Railing. Another type of auxiliary equipment designed to install boots or other devices. Actually, the roof rails look like a pair of rails, but they are installed along the car, usually directly on the body — for example, on gutters. After that, you can install a boot on such rails — or the same crossbars, and already fix the boot on them. Rails can be built-in, non-removable; But such equipment is not provided for in all cars. For this case, removable longitudinal rails are produced.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.
External dimensions (LxWxH)
Boot dimensions in working position; usually indicated for open models and boxes (see "Type"). The capacity of the product directly depends on this parameter, in particular, its suitability for transporting large items. And in the case of boxes, dimensions also affect aerodynamics: increasing the height or width increases drag and fuel consumption. At the same time, it should be noted that the aerodynamics of the container also largely depends on its shape.
For open boots, the height is most often not indicated — after all, its actual value usually depends not on the dimensions of the structure, but on the size of the cargo being transported.
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.
