White fence warning flag spool, 1-3/16" x 300ft. This is one full bulk spool of the material used to make up individual warning flags or warning banners (usually cut into 2 foot strips) Intended to be hung on a fence in between posts or trees on a fence to let deer or other animals know an obstacle is there so they don't run into it by mistake. Warning banners or flags are hung 30" from the ground every 8 feet for deer exclusion.
The flags are lightweight and sway lightly in the wind. Some experts suggest the white color also signifies danger to deer, similar to the underside of white tail deer when running.
Customers also use these flags when first installing a dog fence, or a fence for other pets. Below is a video example of a 2ft strip of the material hung on a fence.
