Door Frame Assembly: Our unique adjustable telescopic molding makes it easy to assemble doors yourself. No nails are required. L shape molding can be adjusted to wall thickness from 3-7/8" to 6". Extensions must be used only if jamb width is greater than 6". An interior wall is usually 4-9/16" thick, if there is plumbing drainage in the wall, it will be 6-9/16". The doors are constructed with solid core(pine blocks), finished with MDF panel and 1mm natural oak veneer. If you are not an expert, you won't see the difference between solid and holow core design. Just knock on the door, and you will realize which one is solid inside and which one is not. Solid core doors are heavier, stronger, last longer and soundproof.
