This part fits on Tradewinds frames. This is a newer style of joint which utilizes a 5/8 inch rail (or track). It measures 8" wide by 4" 5/8" deep. This is a lower joint.
THIS PART ONLY WORKS WITH 5/8" RAILS. If you buy this part, do NOT purchase 1" rails. If you are not certain, measure the rails on your pool. If they are 7/8", they are considered 1" rails. Be aware, that newer pools (2010 & newer) use resin joints, but these new resin joints only fit with 5/8" rails instead of 1" rails.
