Works With Any Trampoline Shape or Size

When we designed the TrampKit in-ground trampoline system, we wanted families who already had a trampoline to be able to convert it to an in-ground trampoline. The hardest part about installing your trampoline is going to be getting the hole dug. Any landscaping company with a mini-excavator can have the hole dug in a couple of hours, or if you're a hardcore DIY'er, you can simply rent a machine and do it yourself.
