Windblown tents, canopies, and umbrellas are the number one cause of injuries and insurance claims at outdoor events where canopies are used. Most canopy manufacturers recommend 24 to 50 lbs. per leg on a 10' x 10' canopy. Help secure your canopy with four 5 lb. interlocking weights for 20 lbs. total from US Weight. This set does not include a carry strap. Made in the USA from recycled plastic material and filled with natural, non-organic river-washed, screened silica sand, these interlocking weights securely capture the canopy legs up to 1 ¼" wide. The no-pinch design makes for easy, safe installation and removal. Trust US Weight to keep outdoor events safe.
