This is the solid bronze interlocking J-hook included with Bronze Threshold Kit A. It installs on the bottom of the door and interlocks with the bronze threshold. It is also available separately for repair, replacement, or restoration work. Each length includes the bronze nails needed for installation. The J-hook is solid, unfinished bronze with a raw mill finish. Minor scratches, marks, and natural surface variations may be present. The bronze will darken and develop a natural patina over time. Mounting holes are predrilled approximately every 10 inches. Custom cutting: The J-hook can be cut to the exact finished length before shipping for $10. Select the next available stock length longer than the finished size needed, choose Cut to exact length (+$10), and enter the finished cut length.
