1/4 inch "U" Bracket is zinc/chrome plated for rust resistance. Includes 8 galvanized screws and 2 bolts/nuts as part of a kit. These are used to temporarily or permanently attach sign boards to a post or a wall. These are great for mounting 911 signs to a post. These can mount your sign vertically or horizontally. **NOTE: There is some extra space between the sign and the sides of the bracket. This does not impede the function of the bracket and often tightening the bracket is all that is needed. Please contact us with any questions or issues!
