You have probably seen this style of wooden air return in a vintage turn of the century house. However, they are usually broken. Many times the joinery was not very good. Also, they were sometimes located in a high traffic area or worse yet, at the bottom of the stairs. Our eggcrate returns use higher quality joinery than the old style. You can get them in surface mount that sits on top of the floor, or if you are laying new flooring you may want to talk to us about a flush mount return with a frame.
The standard woods or red oak and paint grade maple, but we have a plethora of other woods available that you may be looking for.
