Rock grips come in a set of 12. Plastic blow molded Rocks are molded from polyethylene with UV and cold weather protection. These come in 3 different shapes and are roughly 5 1/2" x 4 x" x 2". There are two to different sizes of mounting holes. The attaching screws and bolts are not included. Now smaller sized with the bolt holes that are 3/8" and 2" center to center. This product should last 2 years in harsh conditions and up to 5 years in optimal conditions. Some conditions may require replacement sooner.
**Installation, Safe Use and Maintenance Instructions**
IMPORTANT: Please read for important information. In this material we have tried to provide some requirements stated in the CPSC Handbooks, ASTM F2373-11, F1487-11 and F1148-09. However, we in no way intend for this to be a complete list of requirements. Also these publications are updated frequently with changes therefore, you should read these publications yourself to determine if any part or installation could prove a danger to a child.
To help keep children safe from harm, review installation and maintenance instructions before installing equipment. You can see this PDF.
Due to the thermo dynamics and lower heat transfer properties of plastics they insulate better and don't transfer the heat as quickly. Because of these properties, the Consumer Product Safety Commission (CPSC) recommends plastic slides and plastic surfaces over bare metal.
Regardless of lower heat transfer properties, plastic play equipment can still become hot enough - - in extreme temperatures and direct sunlight - - to cause burns. As is the case with all playground equipment, parents and supervisors must monitor the children in their care, make certain that the equipment is appropriate for their age, and always check playground surfaces for excessive heat before allowing children to play.
Installation: You will need twelve 1 ½" long 3/8" lag bolts and twelve 1 ½" #12 Wood Screws for each set of rocks. Determine difficulty and height wanted. For one set of rocks, use 1" plywood, for taller set, use thicker plywood. Plan configuration wanted for rocks. Place rock on board and mark with pencil where holes need to be drilled. Drill a pilot hole for 3/8" lag bolt for large hole and #12 for small hole for each rock. Then using a 9/16" socket, screw 3/8" lag bolt into rock. Do not tighten until second bolt is installed. Using a 5/16" socket, screw in the #12 wood screw. Tighten both screws. Continue procedure until all twenty-four bolts are screwed in completely. Make sure no sharp point protrudes beyond back of plywood.
Safe Use: This is for children 5 - 12 years old only. Adults should supervise children at all times. Do not allow children to use unsafely. Do not allow it to be used if damaged or wet.
Maintenance: Before and after play season and once a month during play season, check that bolts are tight. Make sure there is no cracked plastic, cracks in wood or splinters. Make sure there are not sharp edges or bolts showing through wood. Replace parts as needed. Maintain detailed inspection and maintenance records for public-use playground equipment.
Any damage from vandalism, abuse or misuse VOIDS all warranties.
