Constructed of a steel plate molded into a recycled rubber base it features 2 carrying handles for easy movement. Easy to use all you do is release the lever and raise the mast to lock it into the upright position. The plastic corner pockets featured on the roll up signs allow for quick and easy mounting. Just insert the corner pocket and press down. The sign will automatically lock into place. To remove the sign, simply life the release lever. The base is skid resistant and stable enough to remain in place during windy conditions.
