Safety is JumpKing’s #1 priority, and our welded enclosure bent pole design keeps the enclosure net away from the enclosure poles while jumping. All JumpKing trampoline frames feature patented T-connectors at each leg and enclosure joint, increasing frame stability and prevents the frame from twisting while in use. The T-connectors are made of rust-resistant galvanized steel, which extends the life of your trampoline and makes assembly easier. 72 galvanized steel springs, 5.5" long are located around the outside of the enclosure net keeps children safe from hazardous pinch points and openings.
