buy a piece of pvc 3-4" and two caps , drill 1/2" hole in one cap, pull rope thru and tie a knot. dont cut the pipe to legnth until you pull up to see just how long it needs to be. cut off and place the other cap on. if you dont want to fight the cap glue on a female pvc screw on cap, then all you have to do is unscrew when using. hope this helps
