Victaulic fittings are designed for easy installation and a neat clean appearance. Fittings for 90°, 45°, and tees are engineered with step-downs to accommodate 1/2:, 1″ 1 1/2″ or 2″ thick insulation. Simply trim the part to the step down that you need.
Remember, there is no additional charge for color. Colors are recommended for indoor use only. Victaulic covers are two piece unsealed.
