This is a Tradewinds Resin Vertical. It measures 54" long by 10" wide at the top, 6 1/2" wide at the middle and 8 1/4" wide at the bottom. Verticals can look similar. It is your responsibility to make sure that your pool utilizes a Tradewinds frame. It is always a good idea to look through your installation manual and find the packing sheet to see specific part numbers that fit with your pool. This cannot be used as a side-vertical on oval pools. However, it can be used along the rounded ends of oval pools.
