This replacement safety netting for your 15ft round trampoline is made from super strong & flexible Terylene thread & the intelligent design uses a free standing net to minimise the risk of accidents involving the upright posts. This netting is designed specifically for 15ft round Big Air trampolines, but it may also be suitable for other 15ft round trampolines with 12 enclosure poles & where the safety netting fits inside the outer ring of safety padding (bottom of netting attaches to jump mat). It is NOT suitable for trampolines where the netting fits outside the safety padding. If you are unsure as to whether this netting will fit your trampoline, please call us for advice prior to purchase. PLEASE NOTE: The poles & trampoline are not included. (Safety net only)
