Window and Door Connectors for Precision Joinery
KNAPP window and door connectors are engineered for professional fabricators, joiners, and manufacturers who demand accuracy, speed, and clean results. These concealed fastening systems simplify the connection of window frames, door assemblies, and façade elements while ensuring long-term strength and alignment.
Each connector is designed to eliminate visible fasteners, providing a seamless architectural appearance and reducing installation time. Whether used in high-volume manufacturing, modular construction, or detailed millwork, KNAPP systems deliver precision and reliability at every stage of production.
Built for Manufacturing Efficiency and Structural Integrity
Developed for both CNC and manual workflows, KNAPP connectors integrate seamlessly into modern fabrication processes. Their self-tightening, adjustable designs maintain consistent tolerances and enable quick assembly, disassembly, or re-alignment on site.
