Carter Lift Bag CBBB-1000 Boulder Bag - 1,000 lbs (454 kg) Lift Capacity

Carter Lift Bag Boulder Bags derive their name from gold dredgers and nugget hunters who use them for lifting boulders in the shallow rivers of California's mother-lode country. They are designed to get a maximum amount of lift from a single lift-point in a minimum depth of water. For example, the 2,000 pound Boulder Bag gets its total lift in less than 3 feet of water, whereas the 2,000 pound Open Bottom Bag requires almost 8 feet of water. These bags are very durable and have been used as air jacks capable of exerting several thousand pounds of force over a large area.
