All necessary prep work along with motor, equipment, device installation, and product support are part of the package, so be sure to ask us about this luxury feature!


Strong and Dependable

Made from laminated veneer lumber with wide, solid premium edge bands and 3/16” thick skins for balance and maximum resistance to warping, you can rest assured that your AG product will stand the test of time.

AG is dedicated to using only the highest grades of lumber available for your project, with each and every piece carefully matched according to wood species, grade, density, color, texture and compatible grain patterns.

Earth-Friendly Practices

AG is passionate about our environment and your family’s health, so the finish products they use are the lowest in volatile organic compounds (VOCs) in the nation, and waste is reduced through recycling and minimal packaging.
