National Hardware N104-786 Double Box Rail Bracket, Galvanized Steel

The National Hardware N104-786 Double Box Rail Bracket is a galvanized steel connector engineered for mounting double runs of #5114 or #5116 box rail systems. Its robust construction and corrosion-resistant zinc coating make it ideal for securing barn doors, storage sheds, trailer frames, and other structures that demand reliable, long-lasting support. The narrow mounting surface makes it suitable for use on corrugated metal siding installations where standard brackets may not fit.

This bracket solves the challenge of securely fastening heavy rail systems while protecting hardware from rust and weather damage. Whether you're building a new structure or reinforcing an existing frame, the adjustable design allows you to position the rail closer to or further from the building surface for a perfect fit. With a 300 lb. safe working load and included fasteners, installation is straightforward and dependable.
