The LowPro 11/11 composite trench cover is anti-slide as it has an innovative Flexi-Edge system which does not need to be bolted down. This greatly reduces trip hazards for pedestrians and reduces installation time. Easy to use and transport, this long-lasting and robust plastic trench cover is used on many work sites in Construction, Excavation, Street Works and Utilities. The anti-slide technology, on the underside and edges of the 11/11 LowPro, is made from a soft, flexible, rubber material which grips the surface reducing unwanted movement. Rubber edges can be replaced to extend the life of your LowPro.
