1" wide rail that has true measurements of 7/8" wide, 3/4" tall and 55 3/4" long (not measuring curvature). Fits 21' round and 21'x41' oval pools.
This part can be interchanged with 5/8" rails (part #1621) but you must also replace all of the joints on your pool to accommodate 5/8" rails. If this part is out of stock, you will not have trouble using part #1818 or #1824 instead because the curvature is very similar.
