The Billow Cast Iron Hook is a cast iron wall hook from Rustic State, sold as a set of two and shaped after railroad spike hardware: a single arm off a backplate, ending in a faceted knob. How big is the Billow hook? Each hook is 2.9 inches deep, measured from the face of the backplate out to the knob. The plate is 2.7 inches wide and 3.8 inches tall, taller than it is wide, and that is the full height, since the arm runs neither above nor below it. The dimension photo shows three screw holes in the plate: two near the top, one centered along the bottom edge. The listing calls the design compact and space-saving. Where does it mount? On a wall, through that backplate. Entryways and mudrooms, bedrooms and closets are the rooms the listing names. One photo puts a hook on white subway tile in a kitchen, another on a wood plank wall beside a mirror and a marble countertop, a third on a plain gray wall. What can it hold? Everyday essentials, kept within reach: Coats and jackets Hats and bags Scarves and accessories Pet leashes, collars and grab-and-go items Towels, a striped one and a cream ribbed one in the photos Hung by the door, it takes the clutter down and leaves the room cleaner and more welcoming. What comes in the set? Two hooks, a matching pair ready to install together. Installation is described as easy, a DIY upgrade rather than a project, and the set lists no other parts. What does the finish look like? The backplate is hammered and the knob is faceted. Functional and decorative at once: rugged character with a clean, polished look that adds rustic charm to the wall.
