Birch, Oak, Maple, Mahogany, Walnut and Cherry can be ordered directly at www.absupply.net. This door meets or exceeds all architectural specifications for construction and quality standards. These doors feature a fully bonded core. This means the stiles and rails are securely attached to the core with adhesives and then are abrasively planed before veneering. This step works to ensure minimal telegraphing of core parts through veneers. These doors are used in commercial, institutional and residential applications.
