Instead of round or square metal spindles spaced evenly, you use glass baluster panels or glass pickets that fit into special railing frames. When someone says “4″ glass pickets,” they’re usually referring to systems where the glass element sits in a 4-inch-wide slot or channel, or where the equivalent spacing/structural component is roughly 4″.
Technically, glass itself isn’t cut into round pickets — but many modern deck rail manufacturers offer glass infill solutions that function like balusters with similar spacing considerations.
Create an outdoor "room with a view," using DekPro or Fortress Glass Balusters. Unlike balusters in other materials, glass balusters are transparent, meaning you can see clear through them. They won't cut into your sightline, so you can enjoy the full beauty beyond your deck, whether that be a sprawling meadow, towering forest, or rolling ocean.
