Understanding Delineator Posts

What exactly are delineators posts?  They are similar to traffic cones except they are skinny and tall making them easier to be seen by cars.  Delineators are used to ‘channelize’ or direct traffic into a certain zone, or to keep it out of a certain zone in the case of a road construction site.

There are multiple brands of delineator posts, and depending on what style you want, you may have to commit to the brand that produces that style.  There are T Top Delineators which have a handle at the top.  There are also Ringtop Delineators which also have a handle, but it’s more of a rectangular handle.  Then there are standard Open Top Delineators which don’t have a handle so they are just flat or open at the top.
