These easy to attach groundbar sets give your Party Tent added stability, especially when used on hard standing. They link together, essentially creating a frame around the base to which the bottom of each wall can be attached by bungee. This makes the whole structure even more stable. Individual sections can be left out to provide uninterrupted entry and exit points. Alternatively, use our groundbar ramps, which provide a visible and hard-wearing means of access. Groundbars can be pegged to soft ground using our groundbar stakes. On hard standing you can apply weights to the groundbars to provide more security. From our many years of exxperience, Norwich Camping would definitely recommend that you consider purchasing groundbars with your Party Tent.
