The set is comprised of 2 ground sleeves units, one for each supporting structure upright. The ground sleeve, which has a depth of 1000 mm, is made of a round section PVC tube with an outside diameter of 160 mm (141.8 mm inside diameter). It is secured to the ground by means of a concrete foundation slab, which will have to be constructed to perfectly anchor the supporting structure.
The assembly distance between ground sleeves also depends on the scoreboard model chosen.
