The new multi roller “Fortis” easily moves heavy planters weighing up to 200 kgs. It can be used indoor as well as outdoor. The production is kept environmentally friendly and chemical-free by using a combination of two traditional wood treating methods. To create an extra strong, solid wood load bearing surface, local conifer wood from PEFC certified forestry has been preserved through a centuries old procedure: Heat treatment makes the wood very durable and resistant to germs. Subsequently, the thermally treated wood, prepared by this method, is treated with natural oil and made water repellent. The load bearing surface of the “Fortis” is attached to two stable carriers made of powder coated, anthracite steel by means of sixteen strong screws. Four smooth rolling soft castors protect sensitive floorings indoors and outdoors. Two of these castors are equipped with brakes so that the trolley can be placed safely in the desired place.
