Who it fits
Good fit for
This roof box suits travelers who need extra luggage space without a massive footprint. The dual-side opening is ideal for those who park in narrow garages or tight lots, allowing you to load gear without getting out of the car. The 11.3 cubic feet capacity works well for weekend trips or moderate road trips. Its waterproof design ensures your items stay dry during unexpected rain. The pre-assembled nature makes it a good choice for buyers who want a straightforward setup process.
Who should skip it
You should look at another option if you require a larger storage volume. This model caps at 11.3 cubic feet, which may be insufficient for long-distance moving or extensive family vacations. If you prefer a single-lid design for simpler mechanics, the dual-side opening adds complexity. The matte black finish may not match vehicles with glossy or colored paint jobs. Additionally, the rigid 12-inch height might not fit all roof rack crossbars, so verify your vehicle's clearance before purchasing.
Verdict: The OMAC 11.3 Cu Ft Dual-Side Roof Box delivers solid capacity and convenient access for everyday travel needs. Its waterproof, UV-protected shell ensures your gear stays secure in various weather conditions.
Key specs explained for this roof box
Capacity: 11.3 cu ft
This volume equals 320 liters of storage space. You can fit large items like luggage sets, camping gear, or sports equipment inside. When shopping for roof boxes, compare this capacity to your typical travel load. Larger families or frequent travelers often need this amount of room to avoid multiple trips. It provides a significant upgrade over standard trunk space for long road trips.
Dimensions: 52 x 32 x 12 inches
These measurements define the physical footprint on your roof rack. The 52-inch length fits most standard crossbars, while the 32-inch width stays clear of vehicle doors. The 12-inch height affects aerodynamics and garage clearance. Check your vehicle’s roof width before buying. This size balances internal volume with exterior aerodynamic efficiency, making it suitable for most SUVs and sedans.
Opening: dual-side
You can access the cargo from either side of the vehicle. This feature is crucial for tight parking spots where one side is blocked by another car. You do not need to move your vehicle to load or unload items. This convenience saves time and effort during travel. Compare this to single-sided models that require ample space on one side for practical use.
Shell Type: PS UV Protected
The shell is made from polystyrene treated to resist sun damage. UV protection prevents the material from becoming brittle or fading over time. This ensures the box remains durable through years of exposure to sunlight. When comparing roof boxes, look for this specification to ensure long-term reliability. It protects your gear from weather-related degradation better than untreated plastics.

Before You Buy This Roof Box
You need to verify your roof rack crossbar width before installing this OMAC unit. The listing states it fits all vehicles, but physical fit depends on your specific rack system. You must ensure your bars can support the 35.2 to 35.8-pound weight of the box plus your cargo. Since it opens from both sides, you need adequate clearance on both sides of your vehicle to access the lid safely. You should also check the 12-inch height against any garage limits or low-hanging branches. This model sits alongside other options in our 1 product guide. It differs from standard single-opening boxes by offering dual-side access. It also varies from larger 15-cubic-foot models by being more compact.

Check before you buy
