Can I get a sheet of Kerfkore that is 8 wide and 4 tall?
No. Kerfkore is only available in 4 wide and 8 tall. The reason it is not available in an 8 width is because the easy splicing method. When using Kerfkore your face material is designed to be the splicing material. When an 8 wide section is needed you just cut the 8 long material into two 4 wide sections. These sections are then placed side by side with a small gap between the sections to duplicate the normal kerf width. The face material is then laminated to the two pieces of Kerfkore and you have now easily produced a product that is 8 wide and 4 tall.
