If you have at least one inch of wall or ceiling space around all four sides of your duct opening then this is an excellent choice for a air return. Standard woods are red oak and paint grade maple. Other woods are available. We can make these in just about any dimensions you might need.
These are ordered by the duct opening dimensions, not the overall size. Pricing is the duct length times the duct width times .64 in the event you have 100 square inches or more. Below 100 square inches the price is a flat fee of $63.95. Shipping is 10%, but at least $12.95.
