Recycled rubber Wear Mats are available in 36” x 36” squares with a 1-1/2” height. The mats are made from the same high-quality recycled rubber that the other PlayGuard products are made from and include up to 92% recycled rubber. The mats are loose lay and can easily be installed under swing sets and at the foot of sliding boards. Wear Mats do not carry a fall height rating and are only recommended to help prevent the spread of wood mulch, pea gravel, or rubber crumb.
