Have you ever wondered what the correct name is for that box on the roof of the car in which owners put skis, suitcases or baby strollers? Many car enthusiasts use different terms: some say “trunk”, some say “trunk”, and others simply “box”. In fact, all these names have a right to exist, but they mean slightly different things.
In this article we will figure out how officially called car roof box in documents, catalogs and among professionals. You will learn about all types of such structures, their features, and also receive practical advice on selection and installation. We will pay special attention to legal nuances - after all, an incorrectly installed box can cause a fine or even an accident.
The material will be useful both for beginners who are just planning to buy such equipment, and for experienced drivers who want to optimize the use of their car for traveling or transporting large cargo.
Official names: what GOST and manufacturers say
According to GOST R 52389-2005 (national standard of the Russian Federation regulating terms in the field of road transport), a design for transporting goods on the roof of a car is called "roof rack". However, this term is rarely used in everyday speech. Let's look at all the options:
- 📦 Roof rack - the most common name in everyday life. Suitable for all structures, including gratings, arches and closed boxes.
- 🧳 Roof case - used to indicate closed boxes with rigid walls (for example, models Thule or Hapro).
- 📦 Roof box - a universal term suitable for both plastic and aluminum structures.
- 🚗 Roofbox (from English roof box) - professional slang, often used in car dealerships and among tourists.
In manufacturers' catalogs (for example, Thule, Mont Blanc, Inno) the most common term "roof box" or its Russified version - “roof box”. In the vehicle's PTS or STS, such equipment is indicated as additional external cargo device, but this is more of a legal formulation than a technical one.
Interestingly, in European countries the term is used to refer to roof boxes "ski box" (ski box), even if it is not skis that are transported in it. This is due to the history of the appearance of such structures - they were originally developed specifically for sports equipment.
Types of roof boxes: comparison table
Not all boxes are the same - they differ in material, shape, mounting method and load capacity. Below is a comparison table of the main types that will help you make your choice.
| Boxing type | Material | Load capacity | Features | Average price (2026) |
|---|---|---|---|---|
| Plastic box | ABS plastic, polypropylene | up to 50 kg | Lightweight, corrosion resistant, wide range of colors. Not suitable for heavy loads. | from 8,000 to 30,000 ₽ |
| Aluminum box | Aviation aluminum | up to 75 kg | Robust, durable, suitable for extreme conditions. Heavier than plastic counterparts. | from 25,000 to 80,000 ₽ |
| Fabric cover | Polyester, nylon | up to 30 kg | Flexible, light, cheap. Does not protect against moisture, suitable for temporary use. | from 3,000 to 12,000 ₽ |
| Universal arc/grid | Steel, aluminum | up to 100 kg | Not a closed box, but a frame for securing cargo. Requires additional straps. | from 5,000 to 20,000 ₽ |
The choice of box type depends on your tasks. For example, for family trips with strollers it is better suited plastic box volume 400-500 liters (for example, Thule Motion XT or Hapro Touring). Ideal for transporting skis or snowboards narrow aluminum box (for example, Mont Blanc Alpine). And if you need to temporarily transport large cargo (for example, furniture), it is enough universal arc with belts.
Legal nuances: what the law says about roof boxes
Installation of a box on the roof of a car is regulated by several regulations:
- Traffic rules of the Russian Federation, clause 23.3 — prohibits the transportation of cargo that protrudes more than 1 meter beyond the dimensions of the vehicle front or back and by 0.4 meters on the sides. For roof boxes, this means that their width should not exceed the width of the vehicle by more than 40 cm on each side.
- Technical Regulations of the Customs Union TR CU 018/2011 — requires that additional equipment does not impair visibility or create interference for other road users.
- Code of Administrative Offenses of the Russian Federation, Article 12.21 - provides for a fine of 500 rubles for incorrect transportation of cargo, if this creates a danger to others.
In addition, according to Order of the Ministry of Internal Affairs No. 399, there should be a box on the roof securely fastenedto prevent it from moving or falling while moving. This means that:
- 🔧 The fastening must withstand double weight load (for example, if the box is designed for 50 kg, the fastenings should hold 100 kg).
- 🚨 Boxing should not be closed
brake lights,headlightsorlicense plates. - 📏 The maximum height of the car with boxing should not exceed 4 meters (for passenger cars this is almost never a problem, but it is important for minibuses).
⚠️ Attention: If you install the box on the roof of a car with tinted windows, the traffic police inspector may require you to show documents for tinting. The fact is that boxing can further limit visibility, and this, in combination with tinting, can be regarded as a violation.
It's also worth remembering that some European countries (such as Germany or France) have stricter rules. For example, in France the roof box must be equipped with reflectors and red flags, if it protrudes beyond the dimensions of the car. If you are planning a trip abroad, check local traffic regulations.
How to choose the right roof box: step-by-step instructions
Choosing a box is not only a matter of aesthetics, but also of safety. Here is a step-by-step algorithm that will help you avoid mistakes:
- Determine the purpose of use:
- 🏂 For skis/snowboards - a narrow long box (for example, Thule Pulse).
- 🧳 For family trips - a volumetric box (400+ liters, for example, Hapro Grand Touring).
- 🚴 For bicycles - a universal arch with fastenings.
- Check compatibility with your car:
- 📏 Measure the length of the roof between the arches (if they are already installed).
- ⚖️ Check the maximum roof load in the instructions for the car (usually 50-100 kg).
- Select material:
- 🔄 Plastic is light, but less durable.
- ⚙️ Aluminum is durable, but heavier and more expensive.
- 🔗 Universal fastenings (for example, Thule Rapid System) are suitable for most cars.
- 🔧 Individual fastenings (for example, for Volvo or Audi) provide better fixation.
- Ignoring the manufacturer's instructions
Each boxing model has its own mounting features. For example, boxes Thule require the use of special keys for fixation, and models Hapro Can be attached without tools. If you ignore the instructions, the box may move during movement.
- Exceeding the permissible load
Many people think that if the box can withstand 75 kg, then it can be loaded to capacity. However the load is distributed not only on the box, but also on the roof of the car. For example, at Toyota RAV4 maximum roof load is 80 kg, and Lada Vesta - only 50 kg.
- Incorrect load distribution
Heavy objects must be kept below and closer to the center boxing If they are placed on top or side, the center of gravity will shift, which will impair the car's handling, especially at high speeds.
- No pre-travel check
Even a securely fastened box can become loose over time. Before each trip, check:
- 🔒 Locks on the box lid.
- 🔧 Attachments to arches or rails.
- 🚗 Are the car doors closed (sometimes the box prevents them from opening).
- Ignoring aerodynamics
Boxing increases drag, which leads to increase fuel consumption by 10-20%. At speeds above 100 km/h the effect intensifies. If you often drive on the highway, choose a streamlined model (for example, Thule Sonic).
Don't forget about aerodynamics. Boxes with a streamlined shape (for example, Thule Motion XT) reduce fuel consumption by 5-10% compared to rectangular models. Also note opening system — side covers are more convenient than the back ones if you have a tall car (for example, Toyota Land Cruiser or Volkswagen Multivan).
☑️ What to check before buying a roof box
Top 5 mistakes when installing a roof box
Even experienced car enthusiasts sometimes make mistakes that can lead to an accident or damage to the car. Here are the most common of them:
⚠️ Attention: If you are installing the box on a car with panoramic roof (for example, Nissan Qashqai or Volkswagen Tiguan), make sure that the fasteners will not damage the glass. For such machines there are special gaskets and shock-absorbing pads.
Before your first trip with the box, drive 5-10 km around the city at low speed (40-50 km/h) and check for any extraneous noise or vibration. This will help identify weak points of fastening.
Maintenance and care: how to extend the life of your box
The roof box, like any other automotive equipment, requires maintenance. Here are some tips to help avoid premature wear:
- 🧼 Washing: Wash plastic boxes soft sponge with car shampoo. Abrasive products may scratch the surface. Aluminum boxes can be washed under pressure, but not closer than 30 cm from the surface.
- 🔑 Lubrication: Lubricate locks and hinges once a season silicone grease (for example, WD-40 Specialist). This will prevent corrosion and freezing of mechanisms in winter.
- 🌞 Storage: When the box is not in use, store it in dry room with temperatures from -10° to +30°. Prolonged exposure to UV rays can cause the plastic to fade.
- 🔧 Checking the fasteners: Before the season (spring and autumn), check the condition of the elastic bands and clips. Worn parts need to be replaced.
Pay special attention seals. Over time, they lose elasticity and the box begins to leak water. To check the seal, stick a strip of paper inside and close the lid. If after 10-15 minutes the paper remains dry, the seals are in order. If it gets wet, it’s time to replace them (for example, a set of seals for Thule costs about 1,500 ₽).
For aluminum boxes it is important to monitor condition of the anti-corrosion coating. If scratches appear, treat them zinc-containing primer (for example, Body 930) to prevent rust. Plastic boxes are less susceptible to corrosion, but may crack in the cold if stored at temperatures below -20°.
What to do if the box starts to leak?
If the box is leaking water, check the seals first. If they are ok, the problem may be a crack in the housing. Small cracks (up to 5 cm) can be repaired epoxy glue (for example, Poxipol). Larger damage will require professional repair or replacement of the cover.
