These hooks are full 1/4" hooks and do not require tethers. They are very durable because they are plastic. I would use these instead of metal hooks with a hole on the board. Avoid multi-packaging and buy these and a set of 6" double hooks and they're good for anything. I bought these when I ran out of metal bottles and they're fantastic. Definitely a better buy than flimsy metal Would buy again if I didn't have 80 to spare.
