Hi I have brought a reimo palm beach sun canopy and side wall now the canopy is great but the side wall has me scratching my head as I have this long pole Adjustable in lean get to about 2.6 metres and what looks like a clamp with no obvious place to go the side wall has a Velcro strip at the top and 3 ties downs at the bottom to match the 3 supplied pegs that then leave the pole and the clamp ?
