Roof Rack Cargo Carrier 51 x 39 x 6 – Heavy Duty Steel Basket

Need more rooftop space? This roof rack cargo carrier fits most crossbars, is rust-proof steel and holds 150 lbs for camping or moving.

Most people make one big packing mistake before a road trip: they cram the trunk until it bulges and forget the roof. The roof rack cargo carrier flips that logic — a 51″ x 39″ x 6″ basket frees up the cabin and gives you an extra 150 lb hauling option for gear, luggage, or bulky boxes.

It’s universal-fit, rust-proof, and built from heavy-duty steel to survive rain, salt, and week-long camping circuits. Ready to stop wrestling suitcases at every rest stop?

Key Features & Real-World Use

  • Durable steel frame – heavy duty construction for load-bearing and longevity; good for long road trips, moving weekends, and overland camping.
  • Rust-proof black finish – corrosion resistance for coastal trips and snowy winters; low maintenance compared with bare metal racks.
  • Generous platform – 51 x 39 x 6 inches gives a spacious low-profile basket that reduces wind buffeting and keeps cargo secure.
  • Safe capacity – rated to carry up to 150 lbs when mounted correctly on approved crossbars.
  • Universal clamp fit – fits crossbars under 3.9 inches wide and 1.3 inches thick; for a 51-inch basket the seller recommends using 2 crossbars for best stability.
  • Accessory-friendly – tie-down points pair with straps, bungee cords, or a cargo net; works with roof rails and load bars on SUVs, wagons, and crossovers.

How to Choose

Pick the right rooftop carrier by checking these basics:

  1. Crossbar compatibility – measure your crossbar width and thickness. This basket needs crossbars under 3.9 inches wide and below 1.3 inches thick.
  2. Vehicle roof rating – verify your vehicle’s roof load limit in the owner’s manual; combine dynamic and static loads when calculating total weight.
  3. Load type – choose a basket for bulky, irregular items like coolers, camping gear, and soft bags; use a rooftop box for weather-sensitive gear.
  4. Accessories – factor in straps, cargo nets, and protective pads for fragile items to reduce abrasion and improve aerodynamics.

Quick Setup & Use

  1. Unpack and lay out the hardware on a flat surface; you should see the basket, clamp plates, bolts, and brackets.
  2. Place the basket on your crossbars, centered left-to-right, and mark approximate mounting spots for two crossbars as recommended.
  3. Attach clamp plates to the crossbars and thread bolts hand-tight; align the basket so it sits square to the roofline.
  4. Tighten hardware to secure the basket; torque by hand until snug and check stability by rocking the frame gently.
  5. Load gear evenly, keeping heavier items forward and low; use ratchet straps and a cargo net for long hauls.
  6. Re-check fasteners after the first 10 miles and periodically on long trips.

Buyer Doubts Solved

  • Will it fit my car? Measure your crossbars. If they are under 3.9 inches wide and under 1.3 inches thick, the basket clamps will fit most load bars on SUVs and wagons.
  • Is assembly hard? Not at all. Basic hand tools and two people make it straightforward; the design favors common bolts and clamp plates over exotic hardware.
  • What about corrosion? The rust-proof black finish and steel frame are made for wet, salty, and snowy conditions; occasional cleaning prevents buildup and salt damage.
  • Will wind noise kill mpg? A low-profile basket is less noisy than taller boxes; aerodynamic packing and soft luggage reduce drag further.
  • Is it safe on highways? Yes when loaded within the 150 lb limit and secured to two crossbars as recommended; inspect tie-downs and clearances before high-speed travel.
