The product holds trees up to 10 feet tall with trunks up to 6 inches in diameter. They use a speed nut design that allows you to easily and quickly push stabilizing bolts into the base of the tree without tediously turning the bolt. Once the bolt makes contact with the trunk, simply tighten the bolt to secure and straighten your tree upright. It's easy as one, two, tree! It features a 1-gallon water reservoir and a wide drip lip at the base to prevent any water from getting on your floor if the reservoir is overfilled.
