Atlantic Water Gardens GK900 Gate Keeper for 9" Weir

The GK900 Gate Keeper is a clip-on guard designed for 9" skimmer weir doors. It protects fish and other pond life by preventing them from entering the skimmer while still allowing leaves and surface debris to pass through. Built for long-term outdoor use, the GK900 reduces the risk of fish loss and keeps pumps running smoothly by limiting animal access to the skimmer throat.

• Fit & Compatibility: Designed specifically for 9" weir doors and compatible with Atlantic Pro Series skimmers that use a 9-inch weir; simple clip-on fit for most standard weir doors.
• Durable Construction: Stainless-steel clips and a polypropylene panel resist corrosion and UV exposure for reliable season-after-season performance.
• Fish Protection: Allows water and floating debris to pass while preventing fish, frogs, and other wildlife from being drawn into the skimmer.
• Low Maintenance: Simple to inspect and clean—removes easily for periodic rinsing and will not restrict water flow when properly installed.
• Specs & Warranty: Lightweight boxed shipping weight around 1 lb and backed by a 1-year limited warranty where offered by the manufacturer.

The GK900 is a cost-effective replacement or upgrade for pond owners who want an easy, durable solution to protect fish and reduce skimmer-related maintenance. Install the Gate Keeper on any Atlantic skimmer with a 9" weir to add a reliable, long-lasting layer of protection without reducing surface skimming performance.
