As I'm planning my order, my wife would like us to go with the traditional chair rail trim. But when I start to "build my order" (24" height), it does not allow me to include traditional chair rail for that height and 1/2" drywall width. Is there a reason for this? It seems like RAILI-HOLD/12 and CHAIR-RAIL/A would work for 24" or 36" height.

Also a question when using the chair rail at corners - how do you manage corners with this system? Do you have to custom-make all inside and outside corners with the RAILI-HOLD? And any tips in how to adjust the chair rail itself for inside & outside corners? Many thanks!!
