Fabric Grommets

Reinforcing Fabric Grommets

The extended neck on the washer of these grommets adds reinforcement so you can use them in thicker material such as woven fabrics. Press them into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material.

Rolled-Rim Reinforcing
Fabric Grommets

A rolled rim provides added grip while the elongated neck and teeth on the washer, also known as a spur washer, add reinforcement and reduce rotation so you can use these grommets in thick materials such as canvas.
