Stainless Gate Closer Hinges

Waterson state-of-the-art gate closer hinges are designed to provide flawless closing support for all exterior and interior gates. For exterior applications, spring loaded gate closers can adjust closing speed based on gate size and mass. At the same time, each hinge’s top-located protection cap ensures durability and longevity by protecting the hinge mechanism from any outside elements.

Applied to indoor applications, each hinge’s fluid motion design creates a quiet and pleasing gate closing experience. Made with stainless steel, Waterson self closing heavy duty gate hinges are built to firmly withstand all weather conditions. They are ideal for commercial gates, residential outdoor use, and interior swinging half doors, to name a few.
