Made from heavy-duty ABS plastic, these skimmers feature a one-piece constructed body with a study external ribbing for superior strength. Similar to a pool skimmer, water is pulled from only the top 1/4" - 3/4" of the pond. They are built into the wall of the pond so as to be as unobtrusive as possible. Instead of the normal door wier found in most skimmers on the market, these skimmers feature a circular floating wier inside the body of the skimmer. This feature makes it much safer for curious fish that swim into the skimmer to get back to the pond. This is in contrast to the tradition door wiered skimmer, which can trap a fish and cause it to drown.  Available in two models: For gunite ponds in black with 2-inch plumbing and for liner ponds in black with 1 1/2-inch plumbing. (Basket is included.) Please note that skimmers are made out of ABS. When cementing ABS to PVC, use specialty cement.
