How to Select and Install Weatherstripping When Eliminating a Vent Window

We LOVE vent windows here at Steele- they have a style all their own and are a sign of the times they came from. When restoring a vehicle and bringing it back to original, a vent window is an essential piece of history that must be present.

BUT in a custom build or hot rod sometimes a vent window isn’t the look you’re going for, and we get it. That’s when it’s time to remove that vent window frame, order some new window glass and start the vent delete process, which can present some challenges.

The OEM style beltline and run channel kits that we offer are made to fit with the vent window in place. What do you do for seals once that’s removed?

That’s when you turn to Steele Rubber Products Universal. The same quality as our OEM style parts but they can adapt to any custom situation- like a vent delete. Your beltline and run channel will both need to be longer and we have just what you need to make that happen.

Special Note: Beltline and run channel are what prevent window rattles in your classic. If your windows are rattling, check these culprits first.


Also called window felts, window fuzzies, cat whiskers, window scrapers, etc., they seal between the inner and outer door panels and the glass to prevent window rattles and trash/water from getting down into the door. They’re the seals you rest your arm on when your window is rolled down.

For more on these parts, visit our article Why Beltline Weatherstripping is Essential to Your Restoration Project.

Beltline Sample Pack

When you’re looking for the right material, either take a look at your original, check out our options online, or reach out to us for a window felt sample pack. Fuzzy or rubber scraper, chrome bead or no bead- we’re sure to have the right part for you! Once you’ve matched the right material, measure across your beltline area (the open area on top of your door where the glass goes) to see what length you need.

At installation time you’ll need to cut it to length, bend it to shape for your window and attach it to the door. You can attach these seals in many different ways. Staples, screws or rivets may have been the original method, but you can also use Urethane adhesive. Don’t know how? Again, we can help.

Run Channel

Glass Run Channel helps to seal and cushion the sides and top of the window when it rolls up into the window frame and provides a guide for the window down in to the door. It was typically felt-lined, flexible metal channels up until the 60’s when felt lined rubber channels started being used.

Run Channel Sample Pack

To find the right material, again you can check out our online listings, complete with pictures, line drawings and measurements, or, we even have a run channel sample pack we can send you.

Did we mention our sample packs are FREE?!

To get the right length, measure the area up and over the windows, where the run channel would normally go, including the additional area where the vent window used to be. Don’t forget to add some length for the material that will go down into the door. Then stop by the website and browse the channel weatherstripping in our universal products. Choose the best one for your project and order the correct length.

Special note: Hard Tops will generally not use Run Channel for the window frame, because… you know… no window frame, but may still have channel in the door. The material is usually the same kind of stuff, just shorter.

For a rubber channel, you’ll need to cut it to length and install it. You can cut these with a simple pair of scissors or some razor snips. These channels are pressed in and generally are just held with that pressure. Some occasionally have clips but if you’re removing the vent window, you’ll likely be removing where those clips go. You can glue them in for a secure hold and we recommend 3M Super Weatherstrip Adhesive (black)

For a felt lined metal channel you’ll need to cut it to length and bend it. We recommend cutting the channel with tin-snips for a nice clean cut. Sharp 90° bends will have to have a cut and mitered joint. These channels are also often held in with pressure but can be screwed, riveted, or glued (depending on the material).

For installation instructions you can find these videos on our YouTube Channel:
