Specifications Eurodetal Magnum 390: what you need to know before buying
Model Magnum 390 belongs to the middle class of autoboxes in terms of volume and load capacity. It is suitable for most passenger cars, including sedans, hatchbacks and crossovers. Here are the key parameters to consider:
- 📦 Volume: 390 liters is enough to transport luggage for a family of 3-4 people for a week-long vacation.
- ⚖️ Load capacity: up to 50 kg (the maximum load on the roof of a car is usually limited to 75 kg, take into account the weight of the box itself - ~12 kg).
- 🔧 Material: impact resistant plastic ABS with UV protection, resistant to temperature changes from -40°C to +80°C.
- 🔒 Castle: central locking with two keys, possibility of installing an additional lock.
- 🚗 Compatibility: Fits most crossbars (eg Thule, Hako, standard rails).
The peculiarity of this model is aerodynamic shape, which reduces noise and air resistance at high speeds. However, at speeds above 120 km/h, it is recommended to check the fastenings: vibrations can weaken the fastening. It is also worth noting that the box comes with universal fastener, but some vehicles (such as those with non-standard roof rails) may require additional adapters.

How to choose an autobox: Magnum 390 vs competitors
To find out if it's right for you Magnum 390, let's compare it with popular analogues in the same price segment. The main selection criteria: volume, load capacity, noise and ease of installation.
- 🔹 Thule Motion XT L (420 l): More spacious, but more expensive (from 25,000 ₽). Better aerodynamics, but heavier (15 kg).
- 🔹 Hako Transporter 380: Cheaper (16,000 ₽), but worse protection from UV rays. Suitable for occasional use.
- 🔹 APT Box 400: Similar volume, but weaker locks. Often counterfeited.
- 🔹 Eurodetal Magnum 450: More than 60 l, but requires stronger cross members.
Benefits Magnum 390:
- ✅ Optimal price/quality ratio.
- ✅ Universal fastener - suitable for 90% of cars.
- ✅ Lighter than competitors (12 kg versus 14–16 kg for analogues).
Disadvantages:
- ❌ At speeds above 130 km/h, the noise increases noticeably.
- ❌ Plastic may turn yellow over time (if you do not use a cover).
If you need a box for rare trips (1-2 times a year), you can save money and take Hako 380. For regular use Magnum 390 — the best choice for reliability.
Step-by-step instructions for installing an autobox Magnum 390
Improper installation is the main cause of car box breakdowns. Follow these instructions to avoid errors:
- Check the cross members. They must withstand a load of at least 75 kg (box weight + luggage). If you have stock rails, make sure they are not plastic.
- Maintain the distance between the crossbars. For Magnum 390 the optimal distance is 70–90 cm. If it is less, the box will “dangle”; if it is more, the lid may not close.
- Use only original fasteners. The set includes 4 metal paws with rubber gaskets. Do not replace them with “universal” ones - this will upset the balance.
- Tighten the nuts crosswise. First lightly secure all 4 fasteners, then tighten them in order: front left → rear right → front right → rear left.
☑️ Check before travel
After installation, test the box while running:
- Drive 500 meters at a speed of 40–60 km/h and listen to outside noises.
- Stop and check that the fasteners have not moved.
- At speeds of 100+ km/h there will be noise, but there should not be any harsh or vibrating - this is a sign of incorrect installation.
⚠️ Attention: If after installation there are gaps of more than 2 mm between the box and the crossbars, use rubber gaskets (sold in auto stores). Otherwise, the fastenings will play on bumps.
Typical operating mistakes and how to avoid them
Even a high-quality car box can be damaged if you do not follow the rules of use. Here are the most common mistakes and their consequences:
- 🚫 Overload: Exceeding the weight of 50 kg deforms the bottom of the box. It is especially dangerous to carry heavy objects (for example, water canisters) without distributing the load.
- 🚫 Ignoring UV protection: If you do not use a cover, the plastic will become brittle after 2-3 seasons. The covers cost from 1,500 ₽, but extend the service life by 1.5 times.
- 🚫 Moist storage: After rain or washing, the box must be dried, otherwise mold will appear inside. This is especially true for owners who store the box in the garage.
- 🚫 Off-season use: In winter, at -20°C, plastic becomes more brittle. If you don’t travel, remove the box and store it in a warm place.
How to extend the life of a car box:
- 🔧 Once a season, check the fastening bolts - they may weaken due to vibrations.
- 🧴 Treat locks with silicone grease (for example, WD-40 Specialist) so that they do not freeze in winter.
- 🧹 Wash the box only with a soft sponge without abrasives. Detergents must be without alkali.
If you plan not to use the box for a long time, lubricate the rubber seals with glycerin - this will prevent them from cracking.

- 👎 "There were no keys for fastenings in the kit, I had to buy them separately" (Review from Ozon, Hyundai Tucson, 2026).
- 👎 "A year later the plastic turned yellow, although I kept it in the garage" (Review from Avito, Renault Duster, 2022).
Most complaints are related to improper use (for example, driving at high speed without checking the fasteners). Owners who monitor the box note its reliability even after 5+ years of use. Average rating on marketplaces: 4.7 out of 5.
What to do if the box starts to leak?
If water appears inside the box after rain, check:
1. Rubber seal on the lid - it could have moved or cracked.
2. Tightening the fasteners - sometimes gaps form between the box and the crossbars.
3. Drainage holes at the bottom of the box - they must be clean (sometimes they become clogged with dirt).
If the seal is damaged, it can be replaced (costs ~800 ₽).
Frequently asked questions (FAQ)
Is it possible to install Magnum 390 on a car without roof rails?
No, this autobox requires crossbars or rails. For vehicles without them (e.g. Lada Granta standard configuration) you will first have to install the cross members (from 5,000 ₽). An alternative is boxes mounted on doorways, but they are less reliable.
What is the maximum weight of luggage that can be carried in Magnum 390?
The manufacturer indicates a maximum of 50 kg, but it is also important to consider maximum load on the roof of your car (indicated in the operating instructions). For example, at Toyota Corolla this is 60 kg, and Renault Logan - only 50 kg (including boxing weight).
Is it necessary to register a car box with the traffic police?
No, a car box is not a change in the design of the car if it is removable and does not exceed the dimensions of the car by more than 20 cm on the sides and 30 cm in the front/rear. However, if the box blocks the rear view (for example, on hatchbacks), the inspector may issue a fine under Art. 12.5 Code of Administrative Offenses (500 ₽).
Which case is better to buy for Magnum 390?
Optimal options:
- Eurodetail original case (2,000 ₽) - perfect size, with ventilation holes.
- Heyner universal (1,500 ₽) - suitable if you can’t find the original.
- Homemade from tarpaulin (from 800 ₽) is a budget option, but less durable.
The main thing is that there is a cover waterproof and had UV protection.
Is it possible to paint the car box if it has turned yellow?
Yes, but only with special paint for plastic (for example, Motip Plastik or Kudo). Regular car enamel will peel off quickly. Before painting, the surface must be cleaned and degreased. An alternative is vinyl film (from RUB 3,000 per wrap).
