D103 is a six-panel solid wood door. The difference between our doors and the competitions is simple - solid wood. Solid wood is the only material we build from. Our stiles and rails are 100 percent solid. They are not engineered, or finger jointed. Our interior door thickness starts out at 1 ½ thick and can be upped to 1 ¾ thick. We can make a slab door for you that is 1 3/8 thick but it is still solid wood. The raised panels in our interior doors are 1 3/8 thick. Many other interior door companies only make raised panels with 3/4 thick panels. The difference is our outstanding quality. Our exterior line features doors 1 ¾ thick and up to 2 ¼ thick for our premium option. Raised panels in our exterior door line are 1 5/8 thick. 2 ¼ doors would receive 2-inch-thick panels. All of our doors are built with quality craftsmanship and from the best furniture solid woods available on the market. Contact our team today for a quote on your custom door project.
