Removable speed bumps are a great way to instantly calm and reduce vehicle traffic speed in a specified location for a temporary period of time. The DH-PSB-1 is a portable folding speed bump designed exclusively for this task, making it easy to calm traffic during certain hours near school yards and playgrounds or during community events and fairs. For optimal portability, each 117" long speed bump folds accordion style to a compact 13.5"L x 10"W x 12.25"H for carrying and storage. A handy bag with handles is included to make it even easier to transport speed bumps on the go. Each bump features black and yellow sections with built-in hinges, a handle cut-out on each end of the bump, along with reflective directional safety arrows. Traction surface works great in all weather conditions, made with durable polyurethane construction built to last.
