The Gazebos we sell do not come with any specific way of attaching them to a base. we did think about including them as standard within the kits however the type of Post anchor needed greatly depends on the base you're applying it to.
We do sell a range of anchors that you can purchase: Post Anchors
You will find that we do offer a range to choose from depending on your base, the most common type we sell are the post Holder screw downs which are ideal for screwing directly onto a pre-made concrete pad or wooden base without the need for any ground work.
We also offer a point post anchor for soft ground
Alos available for are adjustable post anchors which are designed to be concreted into the ground.
