The Global Truss Book Corner Block is a variable-angle connector designed to offer maximum flexibility in truss configuration for F33 and F34 series systems. This black corner block allows users to adjust the connection angle of truss sections smoothly from 0 to 180 degrees, enabling the creation of custom geometric layouts, sharp corners, or unique architectural accents that fixed-angle corners cannot achieve. Constructed from high-strength aluminum, it provides a durable yet lightweight solution for professional staging, exhibit design, and lighting rigging applications. Its robust build ensures structural integrity while maintaining the portability required for touring and production work. The Book Corner Block is an essential component for designers and riggers seeking to build complex, multi-dimensional truss structures that demand both strength and precise angular customization.
