Large triangle vents now ship in two pieces joined by a center mullion. That cuts freight costs and adds support, with a clean look once installed. The mullion slides up the track and connects at the bottom with the supplied screws.

"My vents arrived right on time and turned out perfect. They were very simple to install. Some adhesive, a couple of screws and done."
"Dealing with Mike at Custom Gable Vents couldn't have been easier. He was very polite and easy to work with. I had an issue with the size when it got delivered and Mike corrected it with no hesitation. Great product and excellent customer service! Would highly recommend."

Common questions
Can you match my siding color?
Yes. We match colors from most siding makers, including Alside, James Hardie, Mastic, CertainTeed and Royal, and can cross-reference most Sherwin-Williams colors. We'll mail you a real color sample on request.
Which mounting option do I need?
J-channel receives vinyl, steel or aluminum siding. A standard nail fin surface-mounts over the rough opening for brick, stone and stucco. Front flange and no-flange options fit other jobs. Our mounting guide shows each one.
What is the Wildlife Package?
Our Wildlife Package swaps the standard fiberglass screen on the back of the vent for a sturdier 1/8-inch steel screen, to help keep critters out of your attic. It adds 10% to the vent price and is available on any venting vent, standard or custom. Non-venting vents don't need it, because their sealed back already keeps critters out.
What's the difference between venting and non-venting?
Venting vents have a screened back so air moves through the attic. Non-venting vents have a sealed back and are decorative only.
How fast will my vent ship?
Standard-size in-stock vents ship in 2–3 business days. Custom vents typically take 7 to 14 business days to build. After that, shipping usually takes another 3 to 5 business days, depending on where you are. Ask about our quick-ship option for custom orders. Online orders ship within the US; for Canada, please call us.
Can I order a custom-sized gable vent?
Absolutely. Custom sizes are our specialty. Give us the width × height, material and style you want, and we'll build it to fit. Price a custom vent online.
How do I install my gable vent?
It depends on the type of vent, so call us at 208-589-4020 for the best advice. A basic install fastens the vent with corrosion-resistant screws, with weatherproof sealant behind the nail fin or flange to keep moisture out. The nail fin alone is not flashing: use L flashing or window/door flashing tape over the fin. See our mounting guide and installation terms.
How do I maintain my gable vent?
Maintenance is easy. Clean it with a mild detergent and water as needed. On painted or coated vents, check for wear now and then and touch up as needed.
