Who it fits

Key specs explained for this basket

Material: high-strength plastic

The basket uses durable plastic rather than metal. This material choice prevents rust, chipping, or corrosion over time, unlike traditional steel carriers. You benefit from a lightweight structure that resists weather damage without needing paint touch-ups. When comparing carriers, note that plastic options often weigh less than metal alternatives, reducing the load on your vehicle’s roof rails while maintaining structural integrity for standard cargo loads.

Mount Type: roof-mount (crossbars)

This unit attaches to your vehicle’s existing crossbars using included U-clamps. It requires factory crossbars for proper installation, meaning it is not a standalone solution. You must ensure your vehicle has compatible bars before purchasing. This mount type offers flexibility for different bar spacing. Compare this to fixed roof racks, which require permanent installation, as this design allows for removal when not in use, keeping your vehicle’s profile lower.

Basket Dimensions: 50.1" x 40.2" x 6.5"

These external measurements define the available space for your gear. The 50.1-inch length and 40.2-inch width provide a large footprint suitable for suitcases, coolers, or camping equipment. The 6.5-inch height limits vertical stacking but keeps the center of gravity relatively low. When shopping, compare these dimensions to your typical cargo size. This footprint is ideal for smaller SUVs or cars, offering significant capacity without overwhelming the vehicle’s roof limits.

Size: Large

The large size designation indicates this is the larger option in the product line, designed to maximize storage on compatible vehicles. It is suitable for smaller SUVs or small cars, turning them into larger carriers. When comparing models, note that this size expands travel capacity significantly compared to smaller baskets. Ensure your vehicle’s roof load limits can support the basket plus your gear, as this large footprint accommodates bulky items that smaller carriers cannot.

Design and Build Analysis

The WeatherTech Large Roof Basket is constructed from high-strength plastic, a material choice that distinguishes it from traditional metal carriers. According to the listing, this composition prevents rust, chipping, or corrosion, offering durability without the need for paint maintenance. The unit is fully designed, engineered, and manufactured in America. This construction method ensures a consistent finish that resists weather damage over time. You get a lightweight structure that does not require touch-ups, making it a practical option for long-term outdoor use.

The basket features an open design with external dimensions of 50.1 inches by 40.2 inches and a height of 6.5 inches. This layout allows for easy access to gear, which is ideal for loading suitcases, coolers, or camping equipment. The open structure also facilitates stacking cargo efficiently. If you need additional space, optional length extenders are available. These add 9.4 inches to the length, bringing the total to 59.5 inches. The assembled basket with the extender weighs 29 pounds.

Mounting relies on factory vehicle roof crossbars. Four adjustable U-clamps are included to attach the basket to crossbars with varying spacing. This design ensures compatibility with different vehicle setups. The gray and black finish complements most automotive exteriors. The model number 8ARR01 identifies this specific large size configuration. You must use proper ratchet straps to secure your load, as the basket itself does not include tie-down points for cargo.

Setup and everyday use

Installation requires factory vehicle roof crossbars. The listing notes that four adjustable U-clamps are included to attach the basket to crossbars with different spacing and mounting points. This means you must already have crossbars installed on your vehicle to use this carrier. The basket mounts directly to these bars, expanding your storage capacity.

The open design allows for easy access to your gear. This layout is ideal for loading and unloading items or stacking cargo. You can haul suitcases, coolers, camping gear, and strollers. The listing advises using proper quality ratchet straps to hold your gear down securely. This is a necessary step for safe transport.

The basket measures 50.1 inches in length and 40.2 inches in width. The height is 6.5 inches. These external dimensions define the usable space. If you need more length, optional Length Extenders are available. Adding this piece increases the total length to 59.5 inches. The fully assembled unit, including the extender, weighs 29 pounds. This added length helps with bulky or oversized items.

The material is high-strength plastic. It is designed for years of use. It will not rust, chip, or corrode like metal carriers. This construction simplifies maintenance. You do not need to worry about paint touch-ups or rust prevention. The basket is gray and black. It is manufactured in America. This setup process is straightforward if you have the required crossbars. Daily use involves securing your items with straps. The open design makes this task simple.

Before You Buy This Carrier

Before purchasing the WeatherTech Large Roof Basket, verify your vehicle already has factory crossbars. This unit relies on four adjustable U-clamps for attachment, so it will not fit bare roofs. You must also confirm the crossbar spacing accommodates the included clamps. Since the basket is open, you need to purchase separate ratchet straps to secure gear safely. The plastic construction resists rust and corrosion, meaning you only need to rinse it with water after muddy trips. Do not expect a closed enclosure for theft protection. This carrier suits travelers who prioritize quick access to bulky items like coolers or strollers over weatherproof storage. It sits alongside enclosed roof boxes as a lighter, more accessible alternative. If you need to carry oversized loads that do not fit inside a box, this basket expands your capacity significantly. Just remember the total weight with extenders reaches twenty-nine pounds.

Check before you buy

• Confirm your vehicle has factory roof crossbars installed.
• Check crossbar spacing fits the included four U-clamps.
• Buy separate ratchet straps to secure loose gear.
• Ensure your roof weight limit handles the basket load.
