These double ended snaps are so handy. I have used them to keep the ends of two ex-pens together when I made an enclosure around a small part of the yard. They are great for hanging up water pails as well.
These things are fantastic for clipping a bucket to the fence, clipping fence panels together…whatever you need to clip in a hurry! The double-ended snap makes them handy plus is an extra safety feature if using them to tether an animal for trimming.
