Beautiful aluminum fences are typically made with vertical pickets just shy of 4 inches apart. This spacing is common largely due to pool codes which demand a gap between pickets of no more than 4 inches. Originally, aluminum fencing was a great rust-free alternative to wrought iron ornamental fencing. Then, it really took off as a popular swimming pool safety fence. Small dogs, however, can often slip in between the vertical pickets. Our answer is Puppy Pickets™, which means that the lowest part of the fence has about twice as many vertical pickets, spaced under 2 inches apart so your little pup can’t escape. This smart feature can be added to any of our 18 styles of gorgeous maintenance-free aluminum fencing.
