PowerDoubleBounce™ Trampoline System Specifications
• 14 feet in diameter (24% larger play area/jumping surface than a 9' x 16' rectangular trampoline).
• The frame is heavy-duty, 1.9" diameter, pre-galvanized steel, that is powder coated with a beautiful forest green, textured finish. The frame has a 2mm wall thickness.
• The top trampoline jumping mat is 40 inches tall, for excellent ground clearance (much higher than most other trampolines). This allows us to use our exclusive 10" springs for a deeper, more shock-absorbent landing and an excellent return bounce.
• 128 Extra-Stretch™ High-Performance Springs (10 inches long, tapered, high tensile steel) give our best bounce performance yet still offer a low-impact landing. Our springs are rust resistant using a high-quality zinc-plating process. These exceptional springs, combined with our DoubleBounce design, provide a very forgiving bounce for kids and yet with all 128 springs installed, can still handle a 250 lb. adult.
• Our Permatron® jumping mats are the industry leader in High-Tensile Strength, UV and Water Protection, and performance. Our mats have 10 rows of stitching and a UV shield (compared to just 4 rows of stitching and no UV shield on most other brands). The mats offer approximately 113 square feet of play space.
• We use high strength looped straps and steel V-rings for connecting the springs. Never buy a trampoline mat with grommets that are punched through the fabric... A very poor design that causes the mat to tear and fail prematurely.
• All of our AlleyOop® trampolines include our patent pending all steel "DD" Sure-Lok™ system to prevent the frame from twisting and deforming. Other manufacturers build their frames with slip-fit (male/female) pieces that rotate and twist open over time causing the frame to become loose and wobbly, or even break.
• The frame pad is forest green in color, blending beautifully with the landscape. It is over 14 inches wide and 1 inch thick (no tapering). High-density, gym-quality polyethylene (crosslinked PE), closed-cell foam padding is used across the entire pad surface, not just at the edge. The foam is covered by a high-quality, 21-ounce, reinforced, Polyvinyl Chloride (PVC) outer shell that is UV- and water-resistant. Other manufacturers use a cheap tarp material to cover the foam, which falls apart very quickly.
• Our highest quality and strongest safety enclosure system helps prevent users from falling off of the trampoline, cushions their impacts, keeps the net from breaking/collapsing around them, is rated to withstand an impact of 295 lbs., and lasts many times longer than any other enclosure system on the market. The Unitized design of the DoubleBounce™ System speeds installation time.
• Designed for use with JumpSport® or AlleyOop Sports® Trampoline Accessories (sold separately).
• Maximum single-user weight rating up to 250 lbs in standard 128-spring configuration.*
