This Hammock Wheel Set easily attaches to any tube-style hammock stand up to two inches in diameter. This set features a single U-bolt adjustable anchor ring that secures firmly around the stand to keep the wheels in place. This universal wheel set allows you to move your stand without dragging it on the ground, preventing potential damage to your yard or patio. It also extends the life of your hammock stand by preventing scratches that may lead to rust. Moving your hammock has never been easier. Effortlessly re-position your hammock to take advantage of the relaxing warmth of the sun or simply glide it into the shade for a cool and refreshing afternoon nap.
