Dorman® Black Plastic Corner Connector is used to connect standard aluminum spacer bars at the corners of insulated glass unit frames. In spacer-frame assembly using corner connectors, the spacer sections can be prepared and filled with desiccant before the adjoining sections are joined at the corners. The connector provides a practical press-fit connection that helps secure the spacer profiles in position, maintain accurate corner alignment, and form a stable frame for subsequent sealing and glass assembly.
Manufactured from durable plastic, the Dorman® Black Plastic Corner Connector provides dimensional stability and a reliable mechanical connection within standard aluminum spacer frames. Its non-corrosive construction is suitable for IGU manufacturing environments, while the press-fit design supports consistent positioning and secure joining of adjoining spacer profiles. The black connector is designed for use with compatible standard aluminum spacer bars and provides a practical corner-joint solution for insulated glass frame fabrication.
