Dugite poly heavy duty speed humps (black) are lightweight and easy to install and yet strong enough to handle heavy traffic such as trucks and cars. Made with a honeycomb construction for better strength they are commonly used in all areas where the speed of vehicles must be reduced to create a safe environment. The speed humps comply with the AS2890:1:2004. Finish the speed hump off with end caps that are sold separately and made from the same heavy duty material.
