The 607 series gate hinge is a weld on, bronze & ball bearing, hinge manufactured by welding and machining. These hinges are designed for gates and other applications with high radial loads. The pin is stainless steel to provide corrosion resistance. Bearings consist of two bronze thrust washers and two bronze sleeves for reduced friction. Oil fittings come standard for preventative maintenance. These hinges are designed to be welded on between the post and gate.
The 651 series cam lift gate hinge is a weld on hinge manufactured by welding and machining. These hinges are designed for self closing gates1, doors with seals, or acoustical enclosures. The hinge has a cam machined into either the pin or barrel, which raises the gate up when pushed or pulled open. The force of gravity should pull the door back to a closed position upon release.
