Rickenbacker louvered baseboard register
If you have a wall duct opening that is located in between two baseboards then this is a good option. Standard woods are red or white oak, and other woods are available. We can make these in just about any dimensions you might need.
These are ordered by the overall dimensions, not the duct opening size. Pricing is the overall length times the overall width times .62 in the event you have 100 square inches or more. Below 100 square inches the price is a flat fee of $61.95. Shipping is 10%, but at least $12.95
