Self-piercing grommet press offers alternative to other machines

The ClipsShop CSTON-1 Grommet Attaching Machine uses a spring-assisted stroke to self-pierce fabric using grommets from 1/4 inch to 11/16 inch. The press can be adjusted for exact repeats and is ideal for situations where manual hand presses are too much work, but large pneumatic or electric machines are too expensive.
