They can be hooked over a nail, beam or branch and can even be linked together to make a chain of hooks.
Both styles are 16" long; the small one has 2" diameter hooks at both ends, and the large one has a 2" diameter hook at one end and a 4-1/2" diameter at the other. The large one is more suitable for use with branches.
Either will hold more than 20 lb.
