Full and fractional sizes
Order to the opening you actually have. Every model is made to order, so odd sizes are routine rather than an exception with a surcharge attached.
Standard and custom colors
Standard finishes on every model plus custom color matching across the line, for projects where the diffuser has to disappear into the ceiling.
Backed for life
Every product carries the no noise, no rust, no call backs promise and our industry-leading Lifetime Warranty.* Read the details.
Suffix note: OB denotes an opposed-blade damper option. Submittal sheets show the exact configurations, sizes and options available for each model. *See the warranty statement for full terms, conditions and exclusions.
