It’s hard to see in the photo but I was able to put one down all the way into the ground then another about halfway down and then the one that is most easily seen is actually put in at an angle through the other two. Then I zipped tied it all to the fence!! Needless to say they haven’t gotten out since I did this about 4 days ago. What I really like is the fact you get 25 in the bundle so I am ready for the next hole they dig. My fence is 350 feet of chain link so I appreciate the bundle. Hope this helps. Oh by the way I am a 60 year old women and I did it by myself!! Yeah me!!
