The corner connectors, which are not a part of the system, solve the problem of nonswitching corners in the construction of customised angular solutions. They provide connections with full elasticity. The corner connectors are available as horizontal and vertical versions in a choice of angles with leg lengths of 45 mm. Unlike the standard angles for the 3100.0110I and 3100.0110N profiles, it is possible to assemble all profile types with angular dimensions to the customer’s specification.
