The medium Plant Nappy® is designed to provide spill and leak containment for small and medium plant equipment. The nappy is lightweight and can be left out in all weather conditions. Rainwater runs through the side walls of the unit, whilst any pollutants remain trapped. The side walls are tough and flexible allowing heavy machinery to be ran over them when positioning. The top cover is made from Vinyl coated polyester mesh that is oil & chemical resistant, and this is also abrasion and UV resistant. Can also be used in conjunction with Rubberised Plastic Flexible Drip Tray shown right.
