Product Overview

Gable vents provide added architectural detail with their wood grain finish and sharp distinctive characteristics. They offer key features that have become the benchmark in the industry. Installation is easy with our wide nailing flange, leveling lines, and adjustable stop gauge. Our patented snap-on trim ring hides rough cuts and reduces installation time, while providing a finished appearance once the vent has been installed.

Customer Questions & Answers

The rough opening size seems too small.

The vent is 12 in X 18 in. yet the rough opening size is only 7 X 7. Shouldn't it be closer to 10 in. X 16 in.? Also, is this suitable for use with vinyl siding?
Asked by: Albert
Just opened the box and the vented (screened) area is 10" x 14". Seems like that should be the max rough opening.

vent area

the company answered a question and I don't understand. the rough opening is 7x7 on a 12x18 vent and if you increase the rough opening that would not change the vent area. twice the opening should increase the vent area or are we talking about two different things
Asked by: jacques976
the company I work for also manfactures louvers for large equipment. If I read your question and their answer, I interpret them to mean that when you remove all the restrictions of the 12x18 louver, you would wind up with approximately 7x7 free-air opening or 49 sq inches of free air opening. As you can see from the picture, the louver has 8-slotted openings with very small openings for air passage. You might want to rephrase your question to " what sized opening will the 12x18 louver fit"? and what is the overall OUTSIDE flange dimensions of the louver.

How does a 12 x 18 fit into a 7 x 7 hole?

Asked by: Joe
Thank you for your interest in Builders Edge. Our gable vents are made to fit over the hole not into the hole. The 7 x 7 is an rough opening for this vent, which means it is the smallest the hole can be to get proper ventilation for this vent.
