Windblown tents, canopies and umbrellas are the number one cause of injuries and insurance claims at outdoor events where canopies are used. Help secure your canopy with interlocking weights from US Weight. Most canopy manufacturers recommend 24-50LBS PER LEG for a 10 X 10 canopy. Made in the USA from recycled plastic and filled with cement, these interlocking weights capture the canopy leg more securely than others in the market. The no pinch design makes for easy, safe installation and take down and fits poles up to 1 1/4″ wide. Includes (4) 7.5 LB weights or 30 LBS total weight.
