Shaft Coupler Black Zinc
Iron shaft coupler with black zinc plated surface finish for corrosion resistance and a clean, low-profile appearance. Joins two torsion shaft sections end-to-end for wider door spans requiring extended shaft runs. The black zinc coating provides reliable protection in garage environments and suits installations where a dark hardware finish is preferred.
