Duro Dyne EZ Corners with 5/16” bolt offer a faster, stronger solution for assembling transverse duct connections in TDC and TDF systems. Each corner comes pre-assembled with a heavy-duty 5/16" bolt and nut, eliminating the need to source and install separate hardware. This streamlined design saves time during fabrication and provides a secure, consistent connection across all joints.

The larger 5/16” bolt delivers added torque and holding power, making it ideal for high-pressure or heavy-gauge ductwork. It helps reduce vibration-related loosening and creates a tight, lasting seal. Contractors benefit from fewer stripped threads, faster installations, and less rework, especially on demanding job sites where reliability matters most.

EZ Corners simplify the assembly process with a clean, professional finish. With no loose parts and a fit that aligns precisely every time, they increase productivity without sacrificing quality. Like all Duro Dyne products, these corners are engineered for performance and built to last.
