The type determines the general design of the wipers.
—
Frame. The frame is a system of rocker arms and hinges that gives the wiper its characteristic appearance. The main advantage of models of this type is versatility: an elastic frame allows the wiper to adapt to almost any curvature of the glass. At the same time, such products are inexpensive. On the other hand, they do not tolerate temperatures below zero: even in the "winter" model, the frame can freeze and lose elasticity, which leads to poor efficiency and the appearance of streaks on the glass. This is especially true for inexpensive wipers.
—
Frameless. Wipers that do not have the frame described above. The basis of the design is usually metal plates enclosed in a one-piece rubber-plastic case. This design makes the wiper practically insensitive to icing (in fact, frost resistance depends only on the materials of the blade in contact with the glass). In addition, the body can be given an aerodynamic shape, and frameless wipers are not as noisy as frameless ones. Their main disadvantage, in addition to the higher cost, is that the metal base is made for a specific glass curvature, and such wipers can only be used on those car models for which they were originally designed.
—
Hybrid. Externally, hybrid wipers are similar to frameless ones, but inside the body there is a system that
...works on the same principles as a conventional frame (see above). Due to this, the advantages of both types are combined in one product: on the one hand, frost resistance and aerodynamics, on the other hand, the ability to “adapt” to glasses of different curvature. The main drawback of hybrid models is a rather impressive cost (which, however, is often due not only to the complexity of the design, but also to the use of fairly advanced and durable materials).
— Elastic. Replacement rubber blades for windscreen wipers. The ability to replace the "gum" is provided in many models of wipers: the blades wear out much faster than the base, and replacing them is much cheaper than buying a new wiper. In addition, in this way, in some cleaners, you can also change seasonality.The number of individual wipers included in the delivery.
Modern windscreen wipers are regularly supplied either one by
one or in
pairs. At the same time, paired kits are usually designed for the windscreen and include the main (driver's) and passenger wipers. Buying such a kit can be more convenient than purchasing each wiper separately; just keep in mind that the wipers in a pair can have different lengths (see below).
The length of the wiper, designed to be installed in front of the front passenger seat. Specified only for sets of a pair of wipers (see "Quantity per package").
This parameter is one of the key when choosing: usually, the recommended wiper length is indicated by the car manufacturer. Note that the passenger usually does not need as much space as the driver, so this wiper may be somewhat shorter than the main one.
