BurkerMercer Products will offer installers a new height in 1/8-inch wall base with the company's 4 1/2-inch RetroBase. RetroBase has been designed to make commercial remodeling easier by adding an additional half-inch to its 4-inch base.

The 4 1/2-inch height covers any lines or marks left by removing the old 4-inch base, according to BurkeMercer. RetroBase is offered in all 86 wall base colors in both 1/8-inch rubber and vinyl lengths and rolls. The company will continue to offer 2 1/2-, 4- and 6-inch sizes.
