Canopy weight bags are a good idea but they don't apply all of the weight of the bag to each leg. With these hangers you can apply 100% of the weight of the bag to each leg. At 25 lb capacity per hanger you can keep your tent or canopy in place when the wind blows. If you need more holding power, add another set to the opposite side. You can add up to 4 sets to have 100 lbs per leg. You can even use your own sand bags so long as they have a way to have a loop to hang on the hook. Do not use in strong winds.
