I've always been curious, what makes these better than just going to
the pet store and buying the dog tieouts that do
the same thing. I'm sure these get a good workout being jerked an
pulled by the big dogs.


They also make these (screwit) for use in holding down tents, and a larger
product for mobile homes, and retaining walls. They are not new. Only new by
this person, and new (perhaps) in the aviation market.

The dog types have a crimped place towards the top, that keeps the swivel from
going too high or low. They will twist off at that place, where the crimp has
made a stress concentration. I have a feeling that the steel is of very low
quality, and very soft. Don't ask me how I know that.! :-o
