Speed Bumps are the perfect choice when looking to effectively control traffic at your school or facility. Engineered from heavy-duty recycled plastic with four pre-drilled mounting holes for quick and easy installation. To install, simply place the speed bump in the desired location, and secure it with the provided mounting hardware. Offered in a standard 6ft. length, or an extra-large 9ft. model to ensure the bump is large enough to cover oversized wheelbases. To order, choose between the two size options and select a mounting surface option from the drop-down menus.
