Our 79mm Dado Rail is very popular.   Whilst it is often used for beading, it can also be used at the base or top of a column, or to add additional impressive decorative trim / framing detail to doors, walls, ceilings and furniture.  In the image it is moulded on with a profile Height of 79mm and a 25mm Projection.   We also offer this in 30mm Projection which is the same design, just 5mm thicker on the back of the Dado Rail (where it touches the wall).  

Please note that you may need to cut 100mm from each end of your dado rails to remove moulding flutter.  We leave this on to protect the ends of the boards during transit and it means that your ordered length has more chance of being intact on arrival.
