Available are displays and sales tools for the Grate Accents Register Systemâ„¢ line, which features interchangeable face plates in designer colors and different materials, as well as damper boxes with built-in air filter holders. The floor stocker showcases up to a dozen 4- by 10-inch products. It is especially appropriate for showrooms with limited space, says the company. A second, slim-line style of showcase displays a variety of individual products. Both showroom displays permit adjustments for regional product requirements and preferences, states the company. The Salesman Kit contains several styles and finishes of face plates, a damper box, a filter, and product literature and can be used to show consumers what the product will look like on their floors and how air filtration can be added.
