All of our external door frames have an A-grade quality hardwood or oak veneer that is fixed to a superior quality engineered construction that is perfectly suited for use with all our external doors. They allow for doors to be hung so they open inwards or outwards, and left or right handed. These frames feature sill and frame horns that can be trimmed if necessary. These frames are available in a range of different sizes to suit common external door sizes. Oak frames are available unfinished or pre-finished.
