The weight holds up to 100 lbs. of sand and removes the use for any ugly, eyesore alternative objects. Made from durable materials, the universal weight will last years and withstands severe weather conditions. This listing only includes the Silverback portable weight bag and does not include a portable basketball hoop, basketball goal base, or sand.
