Metal Clamp

These metal rings are used to hold ducting together as well as to hold them up in certain situations. With these metal rings you can easily attach all of your different ducts and pipes together without anything accidentally coming apart halfway through the grow.

You can also use strong adhesive tape and place it over the bracket – or vice versa – in order to increase the strength of both and thus guarantee no terrible mishaps. Available in various sizes, from 100mm to 315mm.
