TKO Dock Doors created the VertiCool door, the only door specifically designed for use with vertical storing dock levelers. The VertiCool by TKO combines superior energy efficiency and lower cost of ownership. The doors feature a 4-inch thick R-23 insulated panel that mirrors the insulated wall panel for superior thermal protection and 48-inch panel heights, reducing the number of panel joints by 50% for energy efficiency and easy cleaning.
