Our 94mm x 30mm Dado Rail is very popular and our tallest Dado Rail.   It is moulded with a profile Height of 94mm and a 30mm Projection,. 

We also do a slightly shorter version 91mm x 25mm Dado Rail ​​​​​that is 91mm Height x 25mm Projection.  

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.
