The "Swiss Hinge" closure joint is a robust, pivotable connecting element primarily used on tank covers, inspection openings, and manhole fittings. It combines the function of a hinge and a locking mechanism. Its special design enables quick, tool-free opening and closing with a defined end position and high holding force. Typically made of stainless steel, it is low-maintenance and ideal for hygienic or demanding environments such as food, chemical, or transport industries.
