2 inch deep Left / Right Triangle Gable Vent By Measure No Flange

https://www.ventgable.com/2-inch-deep-Left-Right-Triangle-Gable-Vent-By-Measure-No-Flange_p_2295473.html The no flange has been the most common choice of installers for sliding into brick openings or gable openings where the look is to be recessed. Once you slide the left or right half triangle gable vent into the opening, it can be fastened in a number of ways determined by the vent installer. Then sealed off to prevent intruding water if necessary. Stronger louvers have been an issue for some manufacturers. With our advanced technology for manufacturing stronger and longer lasting gable vents, we use a 4 fold louver in all our Signature Series left or right half triangle gable vents.
