CHOOSING THE SITE:

SURFACES: Do not install home playground equipment over concrete, asphalt, packed earth, grass, carpet, or

any other hard surface. A fall onto a hard surface can result in serious injury or death to the equipment user. Due to

the variety of places that this product can be suspended, we must urge caution when attaching the Tree House to

your tree.

X.3.1.1 Loose-Fill Materials: Maintain a minimum depth of 9 in (23 cm) of loose-fill materials such as

wood mulch/chips, engineered wood fiber (EWF), or shredded/recycled rubber mulch for equipment up to

8 ft high (2.5 m); and 9 in (23 cm) of sand or pea gravel for equipment up to 5 ft (1.5 m) high. NOTE: An initial fill

level of 12 in (30 cm) will compress to about a 9 in (23 cm) depth of surfacing over time. The surfacing will also

compact, displace, and settle, and should be periodically refilled to maintain a least a 9 in (23 cm) depth.

• Maximum fall height is 84 in (213 cm).

SUPPORT STRUCTURES: Be certain that the overhead structure can support at least 500 lb (227 kg).

• Tree should be healthy and have a minimum trunk diameter of 12 in (30 cm) and a maximum diameter of

24 in ( 61 cm).
