Our 91mm x 25mm Dado Rail is very popular and our second tallest Dado Rail.   It is moulded on a with a profile Height of 91mm with a 25mm Projection. 

We also do a slightly taller version 94mm x 30mm Dado Rail​​​​​​ that is 94mm Height x 30mm 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.
