Well-designed and sturdy, this Australian-made hardware is manufactured from heavy-duty UV-resistant glass-fiber nylon. It is maintenance-free and has a lifetime warranty. Made for long-term continuous use, these heavy-duty hinges are tested to 400,000 cycles. They have a powder graphite-lubricated closing spring made of stainless steel, and the closing speed of the gate can be adjusted with a slot screwdriver. The standard hinge allows for a slight horizontal adjustment and has alignment legs for added strength. The three-way multi-fit hinge has adjustable tension, and can be repositioned vertically and horizontally up to 3/4" after installation. Both styles are 6 3/4" wide when open and 4 7/8" high, are rated to 132 lb load capacity, and come with instructions and screws. Both require #10 screws (included).
