Quality self-piercing grommets need to be supported by quality tooling and attaching machines.
It's easy to use, the extra long handle gives you the leverage you need to punch through the thickest banner material.
And the adjustable stop screw gives you just the right amount of pressure to close the grommet assembly.
It will also work on Polyethelene, Reinforced Vinyl, Coroplast, Tyvek, Celtic posterboard, Styrene, and many other materials.
Don't forget to purchase our #2 Grommets available in Brass, Nickel and Black Nickel.
