This part fits on 9" steel frames. This is an older style of joint which utilizes a 1 inch rail (or track). It measures 5" 5/8" wide, 4" 7/8" deep and 3/4" tall.
THIS PART ONLY WORKS WITH 1" RAILS. If you buy this part, do NOT purchase 5/8" 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.
