Plasticade Trench Covers are lighter than steel and stronger than wood. Made from a single piece of glass-reinforced composite, they are exceptionally rigid. The trench covers are easier and safer to lift into place than steel covers and are more stable and durable than plywood. They come in high-visibility yellow and feature an anti-skid surface as well as a graduated edge that helps to eliminate tripping. Other benefits include less street noise, no need for a cold patch and no scrap value for metal thieves.
