Tired of fetching toys from under the trampoline? Then choose a frame net BERG Basic or Extra frame net. The frame net is attached from the underside of the protective cushion to the ground. Children, pets and toys can no longer fall under the trampoline. Dangerous situations are thus avoided, certainly if you continue to jump on the trampoline. The Extra frame net is a high-quality, weather-resistant net. Zinc-plated eyelets, loops and sardines provide even more secure anchorage Frame nets are only available for our round trampolines. The basic frame net BERG Extra is available in the following diameters: 270, 330, 380 and 430 cm.
