Blank/Closed Hole Rubber Grommets for Sealing

Blank/Closed Hole Rubber Grommets for Sealing & Noise Reduction

(4 products)

4 sizesfrom $0.41ships from Elgin, SCbulk pricing from 50+

Blank grommets, also called closed or solid grommets, have no center opening. They snap into a hole like a standard grommet but seal it completely, which makes them the tidy way to close an unused knockout, a leftover drill hole in a firewall or trailer floor, or a cable hole you no longer need. The ones listed here have a 1/16" groove for sheet metal and thin plastic and fit 5/8", 13/16", 15/16" and 1-1/2" holes.

Choosing a size. Measure the hole, not the old plug, and pick the blank grommet listed for that exact hole size. Then check that your panel is about 1/16" thick or slightly thinner so the groove seats on both sides. For thicker material, a tapered or push-in plug is usually a better fit. If you may need to run a wire through later, a standard grommet with a small opening is easier to reuse.

Blank/Closed Hole Rubber Grommets: questions

How does bulk pricing work?

How fast do orders ship?
Orders usually ship within 24 hours of being placed, by UPS or FedEx with a tracking number, from our warehouse in Elgin, South Carolina. <a href="/pages/shipping-policy">Shipping policy</a>
Can I return parts I don't need?
Yes, within 30 days of delivery. Email us for an RMA number first; items must be in the condition received, with all parts and the original packaging. Refunds may carry a 15% restocking fee (exchanges do not), and the buyer pays return shipping unless the problem is our fault. <a href="/pages/return-policy">Return policy</a>
