This chair is built to hold four bars within a split rail fence post. The quick-snap design makes prepping easy and locates your reinforcement exactly where you want it. Bars are spaced 3 1/2" apart one direction, 3" in the other. Narrow-tipped points keep visibility to a minimum though it helps that they're gray, too. These work with several different split rail fence mold styles and will help you deliver the best possible product quickly and consistently.
