A modern car is not just a means of transportation, but a space that requires optimization, especially when a standard trunk is no longer enough for family trips or outdoor activities. The solution often becomes boxerThis allows you to significantly increase the usable volume without sacrificing the comfort of passengers in the back seat. However, new models from big-name brands can cost almost as much as a used car, which forces many motorists to look for alternatives in the aftermarket.
Buying used boxing is a reasonable compromise between saving your budget and wanting to get a quality product. The used equipment market is saturated with offers, but this is where the risks lie: from microcracks in plastic to worn-out latch mechanisms that may not withstand speed on the track. In this article, we will discuss in detail how to find a reliable option, what to look at when inspecting and whether the game is worth a candle.
It is important to understand that windboxing - is a complex technical product exposed to ultraviolet light, temperature changes and mechanical loads. Competent approach to the choice will allow you to save up to 60% of the cost of a new product, while getting a time-tested accessory, ready for use in any conditions.
The benefits and risks of buying a used carbox
The main motivation for finding a used option is the price. New boxes from market leaders, such as Thule or AtlantOften exceed the cost of budget sets of wheels or even the cost of some used cars. Purchase of used products allows you to purchase a premium model at the price of the Chinese counterpart, while receiving a proven aerodynamics and reliability of materials.
But I decided to buy a used boxYou take responsibility for your technical condition. The plastic from which the body is made loses its elasticity over time. Long stay under the scorching sun without the use of protective compounds can lead to the formation of microcracks that are not visible to the naked eye, but will violate the tightness at the first rainstorm.
⚠️ Warning: Never buy a box with visible cracks around the mounts or locks, even if the seller claims that it is a “cosmetics”. At a speed of 110 km/h, such defects can lead to the destruction of the hull and loss of cargo.
In addition, in the secondary market, there are often models that lack original fasteners. Components for older models can be expensive or discontinued, which will turn a bargain purchase into a headache in finding compatible paws and clamps.
Selection criteria: material, volume and aerodynamics
First, decide on the material. The vast majority of modern boxes are made of ABS plastic. It is a durable, lightweight and flexible material that holds the punch well. Less common are fiberglass or aluminum models - they are stronger, but much heavier and more expensive to repair. When examining the used version of ABS, pay attention to the absence of bloating and stratification.
Boxing volume is a critical parameter that is often chosen by eye. Do not chase the maximum values of 500+ liters if you have a compact crossover. An overloaded roof changes the car’s center of gravity, increasing rolls in corners and braking distance. For a sedan or hatchback, the best choice will be a volume of up to 350 liters, which will allow you to place 2-3 large bags or ski equipment.
Aerodynamics directly affects fuel consumption and noise levels. silhouettes, such as those of the series Thule Force or LuxIt creates less resistance to the air. The angular suitcases of the last generation will noticeably buzz on the track and increase gasoline consumption by 1-2 liters per 100 km.
Use the formula for an approximate calculation: the length of the box should not exceed 75-80% of the length of the roof of the car, so as not to overlap the view through the rearview mirror.
Detailed check of condition before purchase
The process of inspection of used boxing should be thorough and methodical. Feel free to ask the seller to open the box, spin it, look inside with a flashlight. The first thing we check is sealability. Rubber gaskets around the perimeter of the cover should be soft, elastic and fit tightly to the body. If the rubber is choked, cracked or has claws, the box will let water through.
The second critical element is locks and the opening mechanism. In used models, the problem of “fatigue” of plastic around the larvae of locks is often encountered. Try to close the box without a key: it should slam with a characteristic click, but should not hang around. Check the system's operation Click-on or similar central opening mechanisms – all latches must be triggered simultaneously and without jamming.
☑️ Checklist of inspection of used boxing
Be sure to inspect the inner surface. The presence of traces of mold or a persistent smell of dampness indicates that the box was kept closed and wet for a long time. It is almost impossible to remove such a smell, and things in such a box will be constantly wet.
Comparison of manufacturers and models in the secondary market
The market offers a wide range of brands, and each of them has its own characteristics of operation and liquidity. Market leaders keep the price even in the used state, but guarantee quality. Budget Chinese counterparts may be attractive in price, but the risk of finding a model with casting marriage is higher.
Below is a comparative table of popular brands that are most commonly found in sales ads:
| Brand | Average used price (%) | Reliability of plastic | Repairability |
|---|---|---|---|
| Thule | 60-70% of the new | Tall. | High (there are parts) |
| Atlant | 50-60% of the new | Medium/High | Medium |
| Lux | 40-50% of new | Tall. | Low. |
| China (NoName) | 30-40% of new | Low/Mediocre | Absent. |
Models. Thule Often have a double opening system, which is convenient with a narrow parking. Boxing Atlant They are famous for their width and capacity, but can be noisier at high speeds. When choosing a specific model, read reviews about the years of release, which are presented on the secondary market, as technologies and materials may change.
Secret Signs of the Original Thule
The original Thule boxes have a laser engraving of the logo on the inside of the lid, not just a sticker. Also, the code (molds) and the date of production are often knocked out at the bottom. The plastic of the original is to the touch more matte and rough, while cheap copies often have a glossy "fat" shine even in black.
Installation Nuances and Compatibility with Railings
Buying a box is only half the battle. The second half is to install it correctly on the car. Most modern boxes are universal and suitable for longitudinal railingsAnd for the transverse arcs. However, it is important to check the type of attachment: T-slot (clamping in the groove) or paw girth.
If you buy a used box without mounts, make sure you can find the right ones separately. Universal paws may not provide the desired fixation rigidity for a particular boxing model, resulting in vibrations and noise. The distance between the mounting points on the bottom of the box should correspond to the ability to adjust your arcs.
⚠️ The maximum static load on the roof of most cars is 75-100 kg, but dynamic (in motion) - only 50-75 kg. Do not overload the box, even if its stated volume allows.
For installation, a special tool may be required, although most often the hexagon key included in the kit is enough. The puff should be uniform: first, the central mounts, then the extreme, with a recheck of the forces after the first 50 km of run.
Recovery and maintenance of purchased box
After purchasing used products, it is recommended to carry out a number of recovery procedures. The first thing to do is to thoroughly wash the box inside and out using soft autochemistry. Aggressive solvents can damage the structure of the plastic or wash away the protective layer.
To restore the elasticity of seals, use a special silicone lubricant. This will prolong the life of rubber and improve leakage. If traces of oxidation (white coating) are noticeable on the surface of the plastic, you can try to restore color with polyreole for plastic, but this is a cosmetic measure.
Regular lubrication of locks and seals with silicone is a mandatory procedure before each winter season, which will prevent the lid from freezing and jamming the larvae.
Check the tightening of all screws and bolts inside the opening mechanism. With active operation, they could weaken. If necessary, tighten them, but without fanaticism, so as not to break the thread in plastic bushings.
Where to look and how to safely complete a transaction
Search for used boxes is best on specialized forums, in profile groups of social networks or on popular message boards. Forum residents often keep a better eye on their property, and there is a higher chance of finding a model in perfect condition with a history of service. When communicating with the seller, be sure to clarify the reason for the sale and storage conditions.
When meeting for inspection, take a flashlight and, if possible, a couple of liters of water to check the tightness (at least local). Having agreed on the price, do not forget to check the completeness: the presence of keys, instructions and, most importantly, fasteners.
Buying used boxing is a great way to get a quality product at a discount. The main thing is to take your time, carefully inspect the product and understand what you are buying. Good shopping and smooth roads!
Can I paint the box in the color of the car?
Yes, it is possible, but it requires preparation. ABS plastic must be thoroughly cleaned, degreased and applied a special soil for plastic. Ordinary car enamel without soil and plasticizer will not last long and will begin to peel due to the flexibility of the body.
How to get rid of the smell of mold in used boxing?
It is necessary to wash the inside with a solution of vinegar or a specialized salon cleaner. After that, leave the box open for a few days in a dry, ventilated place (but not in direct sun). You can use odor absorbers based on activated carbon.
How safe is it to drive a boxing car on the track?
Provided the locks are serviceable and correctly installed, it is absolutely safe. Modern boxes pass crash tests and are designed for speeds up to 130-140 km / h. However, remember that the presence of cargo on the roof increases sailing and braking distance.
What to do if the keys to used boxing are lost?
Many boxes (especially Thule) have a lock code, which allows the official dealer to order a new set of keys. If there is no code, you will have to drill the larva or call the master, which will entail additional costs.
