Roof rack cargo shopping isn't one-size-fits-all. You may need the mounting pieces for an existing carrier, a set of stoppers to keep cargo from sliding, a zippered soft bag for the rack, or a full-sized hard basket. The four listings here are spread across those use cases, and their listed prices range from $56.36 for a load-stop set to $519.71 for a 90-inch heavy-duty roof rack cargo carrier.
Quick take
If you're replacing the fastening hardware for a CURT roof rack cargo carrier, the CURT 19231 Replacement Hardware kit is a direct fit for the 18115 model. If you want the most enclosed steel basket, the 90 x 50 x 6 inch Heavy Duty Roof Rack Cargo Carrier is the largest hard option here. If you just need a cargo stop for a T-slot rack, the 4Pcs Stainless Steel Load Stops are the lowest listed price. And if you prefer a waterproof soft bag, the Rola 48 x 19 x 22 Inch Roof Cargo Bag fits that slot.

Product notes
CURT 19231 Replacement Hardware for Roof Rack Cargo Carrier 18115 19231
This kit is aimed at someone who already has the CURT 18115 roof rack cargo carrier and needs the brackets, bolts, nuts, and other attachment pieces for a fresh setup. The listed price sits between the load-stop set and the hard basket, and the kit does not include the carrier itself. For a shopper who owns the matching carrier, this is a direct way to refresh the hardware rather than replace the whole system. For someone without that carrier, the component set doesn't add cargo capacity on its own.
90 x 50 x 6 Inch Heavy Duty Roof Rack Cargo Carrier
This is the biggest-ticket item in the group, with the highest listed price in this set. Its listed dimensions are 90 x 50 x 6 inches, and it has a 250-pound load capacity, so it can handle bulky luggage, camping gear, or sports equipment. The basket is made from alloy steel with a weatherproof coating, and it folds, according to the listed attributes. The main consideration is the price: it costs far more than the other three options here, so it only makes sense if you regularly need a large, rigid roof carrier rather than a soft bag or simple stops.
4Pcs Roof Rack Load Stop Stainless Steel
At the lowest listed price in this group, this set of four stainless steel stops is meant to fit a T-slot roof rack. The individual stops measure roughly 4.61 x 3.23 x 1.18 inches, so they act as small bumpers that keep loads positioned on the rack. They don't provide any enclosed storage, and they require an existing rack to be useful. If you only need a simple way to keep loose gear from creeping forward during travel, these are the least expensive listed option here. The stainless steel material is a visible part of the design, and the set includes four pieces.
Rola 48 x 19 x 22 Inch Black Waterproof Roof Cargo Bag
The Rola bag is a soft-sided, waterproof option with a concealed zipper and storm flap, and it is listed at $58.99. Its 48 x 19 x 22 inch dimensions make it a medium-sized carrier for an SUV or rack. The trade-off is that it is a soft bag rather than a rigid basket, so it lacks the structural shell of the 90-inch carrier. If your priority is keeping contents dry without spending close to the top of this price range, this bag sits near the lower end.
Final recommendation by use case
- Existing CURT carrier owner: The CURT 19231 Replacement Hardware is the only hardware-only option in this set, so it makes sense if you already have the 18115 carrier.
- Large-load hard basket shopper: Go with the 90 x 50 x 6 Inch Heavy Duty Roof Rack Cargo Carrier if you need the biggest listed footprint and a 250-pound load capacity.
- Waterproof soft bag shopper: The Rola Waterproof Roof Cargo Bag covers that need with a zippered, soft-shell design.
- Minimal cargo-stop shopper: The 4Pcs Stainless Steel Load Stops give you four pieces for T-slot racks at the lowest listed price.
