Premier Door Series

Lag Bolt Design

The Premier door features our signature lag bolt design. These 6″ bolts guard against the separation that moisture can cause. We believe that you deserve the beauty of genuine wood. We manufacture the Premier Door with real wood, giving you a perfect surface to stain any color you choose.

Glass System

Solid wood frames are used to install the insulated glass in each Premier Door. These doors accept standard 1″ glass commonly used in steel doors.

Styles & Sidelights

You can choose from 20 different styles that include solid panels, all glass panel or a combination of both. With 5 styles of sidelights to accessorize the door you will have the perfect entrance.


A beautiful door can have a dramatic look in any room, adding architectural detail and style to make it a focal point. Koch doors are solid core and can also be used as pocket doors and barn doors.
