Who it fits

Key specs explained for this carrier

Capacity: 14 cu ft

This volume determines how much gear you can haul. You get enough room for luggage, camping equipment, and bulky items. It supports a maximum load of 150 pounds. This makes it suitable for family road trips. Compare this capacity to smaller 12 cubic foot boxes if you have less cargo or larger 15.5 cubic foot models if you need more space for extended travel.

Dimensions: 62.5 x 32.48 x 13.19 in

These measurements define the physical footprint on your roof. The length and width affect aerodynamics and clearance between vehicles. The height impacts roof clearance and garage access. You should measure your vehicle's roof space before buying. Compare these dimensions with other carriers to ensure the box fits your car without obstructing visibility or exceeding legal width limits.

Opening: Dual-side

You can open the lid from either side of the vehicle. This feature allows quick loading and unloading from the passenger side without walking around the car. The wide 15-inch opening provides easy access to your gear. This is helpful when parking in tight spaces. Compare this to single-sided opening boxes, which require you to move to one specific side to access your items.

Shell Type: ABS + PMMA

This material combination provides strength and impact resistance. The glossy exterior withstands sun, rain, and harsh outdoor conditions. It protects your belongings during every trip. The durable shell helps maintain the box's appearance over time. Compare this construction to cheaper plastic options that may crack or fade faster under prolonged exposure to weather and UV rays.

Design and build details

Before you buy this box

Before adding this Relaxcabine carrier to your cart, verify your roof rack crossbars. The listing states it fits round, square, and most aerodynamic bars. Tool-free installation helps, but you must ensure your existing hardware supports the 150-pound load limit. Check the width of your crossbars against the 32.48-inch box width to ensure proper clearance.

Consider the dual-side opening. The 15-inch passenger-side access is useful in tight parking spots. However, verify your vehicle’s roof height allows the lid to open fully without hitting side mirrors or the rear window.

Upkeep is minimal. The ABS and PMMA shell resists sun and rain. Wipe it clean after muddy trips to maintain the glossy finish. This 14-cubic-foot option sits in the mid-range capacity among the 1 products on this page. It suits families needing extra gear space without the bulk of larger carriers.

Check before you buy

• Confirm your crossbars are round, square, or aerodynamic.
• Check roof height for full lid clearance.
• Ensure crossbar width supports the 32.48-inch box.
• Verify total load does not exceed 150 pounds.
