Grommet Types & Uses

Published: June 11, 2025

Note: Albright's Supply currently only carries PLAIN grommets.

When it comes to reinforcing holes in fabric for ropes, cords, or wires, grommets are the go-to solution for many upholsterers. These small but mighty components consist of two pieces that press together through a pre-punched hole to strengthen the material, preventing tearing or fraying. Whether you’re working on curtains, tarps, sails, flags, or bags, grommets offer durability and clean, professional results.

Where Are Grommets Used?
While most commonly seen in window treatments and drapery panels, grommets are also widely used in outdoor and industrial applications—including marine upholstery, tents, banners, bags, and even fashion items. Essentially, any project requiring a secure pass-through for cords or fasteners can benefit from grommet reinforcement.

Styles of Grommets
There are several styles of grommet designed for specific needs and fabric weights:

  • Plain Grommets
    The standard choice for general or light-duty applications. They are versatile and pair with plain, tooth, or neck washers.
  • Rolled Rim Grommets
    Designed with a slightly thicker material and a rolled edge for added strength, these are ideal for heavy-duty projects. They are used with spur washers for extra holding power.
  • Self-Piercing Grommets
    Save time by cutting out the hole-punching step! These grommets feature a sharpened edge that pierces the fabric while being set. Note: They are not recommended for thick or multi-layer fabrics.

Washer Types: Finding the Right Match
Grommets typically require a matching washer to hold everything securely in place. Here's a breakdown of washer options:

  • Plain Washers
    Ideal for stationary or light-duty projects.
  • Tooth Washers
    Have interlocking teeth that grip into the fabric. Great for medium to heavy-duty use. Also available in a small tooth version for self-piercing grommets.
  • Spur Washers
    Offer more teeth for an even stronger grip. Perfect for demanding conditions, especially where fabric may move or flex—such as marine applications.

Materials & Finishes
At Albright’s Supply, we offer plain grommets and washers in brass and nickel finishes. Both options provide excellent resistance to corrosion, making them suitable for indoor and outdoor use. We also carry grommet kits that include everything you need to get started: an inserting die, hole cutter, hardwood block, and a selection of brass grommets.

Grommet Sizes
Grommets are sized by number, with each size corresponding to a specific inner diameter. For example, a #1 grommet has an inner diameter of 9/32". Be sure to choose the right size for your project to ensure proper function and a clean finish.

Installing Grommets: A Quick Guide
To install a standard grommet, you’ll need a:

  • Hole Cutter
  • Hardwood Block
  • Inserting Die
  • Mallet

Step-by-Step:
1. Place your fabric on top of the wooden block.
2. Position the hole cutter where you want the grommet and tap with a mallet to punch through.
3. Insert the male half of the grommet from the back side of the fabric.
4. Place the washer on top, concave side facing down.
5. Position the inserting die over the washer and tap with a mallet until the grommet is flush and secure.
