Speed Bumps are the perfect choice when looking to effectively control the speed of traffic at your school or facility. Constructed from heavy-duty recycled rubber with three reflective yellow stripes painted directly onto the rubber material. Units are easy to install, simply place the speed bump in the desired location, and secure it with the provided mounting hardware. Each speed bump measures 72in.L x 12-1/2in.W x 2-1/2in.H, this ensures that the parking lot bump is large enough to cover any standard wheelbase. To order, select a mounting surface option from the drop-down menu.
