V-Groove Design

Our standard distance between V-Grooves is

 3 1/2″ starting at the center of the panel

and repeating until we reach the edge of the panel. End panels will vary in size depending on the width of the door.


V-Groove doors are available in SL- 1 3/8″, IM-1 3/4″ and 1 3/4″ Fire Rated Doors. They give you added design options and are available in most wood species.


V-Groove doors come in a wide variety of styles and can be ordered in SL- 1 3/8″,  IM-1 3/4″ and 1 3/4″ Fire Rated Doors.

Arch Top:

Arch top doors have a 2 1/2″ drop from the highest point of the arch to the lowest.


The V-Groove series offer a selection of up to 31 different wood species, guaranteeing that your style and taste will be reflected in your home. For the most pleasing and consistent grain and color our doors are constructed from top quality products.



The decorative profile on the edge of the stiles and rails is called sticking and combined with your panel choice will create any style you desire. Profile options are available in both veneered and in MDF.
