Nailor Models 1602J, 1604J, and 1606J are architecturally styled non-drainable louvers utilizing high performance J style blades, crafted with a clean continuous architectural appearance that will visually compliment any structure’s exterior. The blade design provides protection against general weather conditions where water infiltration is not a primary concern, with low pressure drop characteristics and a high free area. Standard concealed architectural mullions allow for a smooth, continuous look. Reinforcing bosses run the full length of each blade for superior strength. Suitable for use in ventilation, exhaust and low to medium velocity intake applications, ideal for use in specialty shape and architectural applications. Available in channel, flanged, or glazing adapter type and installs easily in most common wall configurations and mechanical installations. Nailor’s architectural non-drainable louvers are engineered to be aesthetically appealing as well as mechanically enduring.
