This FLEXNET DOME is for 22’ to 24’ diameter above ground pools. All 7 parts are included EXCEPT FOR THE POLES that are inexpensive PVC pipe. The Owner’s Manual contains easy assembly instructions as well as a chart with all the requirements for the poles and links to your local hardware store for purchase. Two adults can assemble your FLEXNET DOME on your pool in under an hour because there are no bolts or screws. Windy days with 40 mph gusts? When installed per the Owner’s Manual, the 40 mph wind is no problem. The FLEXNET DOME releases most of the wind thru the net and flexibility of the poles. As you can see in the photos, the wind and sun go thru the net so you still have the outdoor experience. Worried about big storms? With no bolts or screws you can dismantle the FLEXNET DOME in 30 minutes, or if the storm isn’t too big just remove the net and replace after the storm. Oh, and you like to tan? You tan like the FLEXNET DOME is not there.
