Lag Bolt Construction

Koch and Company is committed to delivering quality, hand crafted doors to your home.

We turn positive first impressions into lasting ones by building our doors to stand the test of time. The process begins with the selection of the finest hardwoods and plain-cut veneers. Stiles and rails are edge glued and have a lag bolt assembly to ensure long-term structural integrity. Lag bolt construction is a signature feature of Koch Doors. Bored through door edges to secure stiles and rails, these long metal bolts are far stronger than wood dowels used by other manufactures, and guard against joint separation.

By using specially engineered core materials that resist moisture and minimize the effect of climate and temperature changes, we eliminate the prime causes of splitting and cracking.

Our door panels are set into compression foam bumpers that keep them centered and absorb the effects of expansion and contraction. After assembly, our doors are trimmed to exact width and height for a consistently precise fit.

Three-phase sanding includes a final hand sanding to remove any cross-grain scratches. We eliminate glue residue with the aid of black lights and individually inspect every door before it is carefully packed and loaded for delivery.

All our doors are built by skilled craftsmen, using modern equipment, who are dedicated to making the finest doors produced in America. The result is a door that fits properly, is ready to hang, and provides lasting value.

Koch doors are proudly made in America, supplying jobs to American workers.
