Question: Can this be used for a rooftop cargo carrier?
Document: For the price, this is a perfectly fine way to hang stuff in the garage. We used it to hang a rooftop luggage carrier. The straps were just long enough to go around our carrier, and it is holding it now  above head-height and out of the way. Mounting it required a trip to the hardware store to buy a 2x4, lag screws and washers (to attach the 2x4 to the studs in the ceiling), and wood screws to attach the pulley's brackets to the 2x4.
Works great. Using it to install and remove YAKIMA  cargo carrier on MERCEDES GL 450. Easy to do by myself.
This can be easily done with a drill bit and cordless drill. I then attached the black mounting assembly to the 2x8 once again using a high quality lag bolts AND 2 washers to distribute the weight (2 bolts PER bracket).Direct mounting to your ceiling.On items like the Thule cargo carrier I simply drilled out the hole on the bracket to allow it to accept a large lag bolt and washer and merely bolted it directly to the ceiling (ensuring you are going into a floor joist).
I have a low garage, about 8 feet and used this system to hang my car's roof 18 cubic ft cargo box. The straps are barely long enough to get around it, but did the job. The system itself is simple and to the point.What I don't like is that the system hands low off the ceiling beam and the cargo box, or kayak if that's what you are using it for, hangs very low.
The quality of the ropes isn't great, but they're sufficient for the task, it appears. It took us longer to install and hang the whole thing than we had anticipated due to the trip to the hardware store and a little confusion over the ropes. It also required a little extra attention when actually hoisting the carrier because the ropes slip off their tracks in the pulleys pretty easily. But it is now doing exactly what we purchased it for and seems like a perfectly fine product.
Very sturdy and versatile. I don't have a kayak but was able to use it as a clothing display for a garage sale and just pulled it up out of the way, down for the next days. I also used it for my bike. The price was amazing.
I used these to hoist an 84lb scanoe up to the garage ceiling. Works well. Getting the measurement right and finding the studs was a small challenge. Theses work great and are holding well.
The one thing I will say for this is that the straps are REALLY long. They're made to hold a canoe off the ground so if you hang a kayak from an 8 foot ceiling, it hangs at chest height. We just used different straps and it works like a charm. Holds everything off the ground and the locking mechanism is easy to use.
They were very nice and emailed me out the instructions! Once I had them it was easy to put everything together correctly! Overall it works okay.. but binds regularly going up and down as the metal latch used to stop the rope is not very well designed. So I have to be extra careful when I tie down canoe after hoisting it up so that the rope does not slip! The rope is also not long for this world as the latch is causing it to fray.
You simply wrap the excess rope around this to secure your load. On items that are rarely used I fore-go this step and merely wrap the excess rope around the item itself. This works out great on items you rarely use or where you don't want the rope in your way. For instance for me I only use my ladders a few times a year so I just wrap the rope around it to secure it.
Answer: yes
