This guide compares omac car rooftop cargo box alternatives to help you find the right fit. The original OMAC model offers 11.3 cubic feet of space with dual-side access and a pre-assembled design. These features make it easy to load gear from either side of your vehicle without climbing onto the roof. Its waterproof hard shell protects contents from rain and UV damage. However, you might prefer a different size, weight limit, or aesthetic finish. Some drivers need more volume for longer trips, while others prioritize a lighter unit for better fuel economy. Others may want a specific color or a higher load capacity for heavy equipment. We selected these alternatives because their specifications overlap with the original OMAC box. Each option shares key traits like hard-shell construction or side-opening mechanisms. This list covers 6 similar picks that match your core needs while offering distinct advantages. You can compare dimensions, weights, and capacities side by side. This approach ensures you find a carrier that fits your roof rack and storage requirements perfectly.

Our top pick: OMAC 11.3 CuFt Hard-Shell Roof Box.

How each alternative compares to OMAC

DNA Motoring 13 cu ft Hard Shell Roof Box

The DNA Motoring 13 cu ft model offers 1.7 cubic feet more volume than the OMAC. It measures 56.3 inches long and 36.8 inches wide, making it larger in footprint. You gain extra space for bulkier items without a significant weight increase. It includes a lockable feature for added security, which the OMAC data does not explicitly list. However, it lacks the pre-assembled convenience of the OMAC unit. You may need to spend more time on initial setup. Choose this if you need more capacity and do not mind manual assembly.

VISRACK 13 cu ft Hard Shell Roof Box

The VISRACK 13 cu ft box provides 1.7 cubic feet more storage than the OMAC. It is lighter at 27.8 pounds compared to the OMAC’s 35.8 pounds. This makes it easier to handle during installation. It features dual-side access like the OMAC but emphasizes tool-free setup for quicker mounting. The width is slightly narrower at 29.5 inches. This may suit vehicles with tighter crossbar spacing. You trade some internal volume for reduced weight and simpler installation. Pick this if you prioritize lightweight design and easy mounting over maximum storage capacity.

Goplus 14 cu ft Dual-Side Opening Roof Box

The Goplus 14 cu ft model offers 2.7 cubic feet more space than the OMAC. It supports a load capacity of 165 lb, which is significantly higher than typical limits for smaller boxes. It measures 63 inches long, making it the longest option here. This length accommodates longer items like skis or kayaks better. It retains the dual-side opening feature for convenient access. The weight is lower at 25 pounds. Choose this if you need to carry heavy loads or long gear. You gain substantial capacity and strength compared to the OMAC.

Ausum Motor 14 cu ft Dual-Side Box

The Ausum Motor 14 cu ft box provides 2.7 cubic feet more volume than the OMAC. It is designed for crossbar spacing between 24.0 and 29.1 inches. This specific fitment ensures a secure mount for vehicles with standard rack spacing. It offers dual-side access and a glossy black finish. The weight is higher at 45 pounds, making it heavier to lift. You gain more internal space and targeted compatibility. However, the increased weight may make handling more difficult. Select this if your vehicle has compatible crossbar spacing and you need extra room for travel gear.

Runave 15.5 cu ft Dual-Side Roof Box

The Runave 15.5 cu ft model offers 4.2 cubic feet more space than the OMAC. It supports a load capacity of 150 lb. This makes it suitable for heavier cargo loads. It measures 58.3 inches long and 35.4 inches wide. The dual-side opening allows access from either side of the vehicle. It is available in white, offering a different aesthetic than the OMAC’s black finish. You gain significant volume and strength. The trade-off is a larger footprint that may not fit all roof racks. Choose this if you need maximum capacity and heavy-duty performance.

Pidock 16 cu ft Hard Shell Roof Box

The Pidock 16 cu ft box provides 4.7 cubic feet more volume than the OMAC. It is the largest option in this comparison. It measures 58.3 inches long and 35.4 inches wide. It features dual-side access for convenient loading. The weight is listed as 130 pounds, which is exceptionally high. This likely indicates the total weight with packaging or a data error, as it exceeds typical cargo box weights. You gain the most storage space available. However, the extreme weight and size require robust roof racks. Pick this if you need maximum volume and have a heavy-duty vehicle setup.
