Men's Gold Chain Necklaces & Pendants Gold Jewelry for Men Page 2 Reinforcement Tube For SiteCop Plus And Standard 48 x 1200mm. This reinforcement tube is designed specifically for the SiteCop Plus or SiteCop Standard Speed bumps. This tube sits inside the speed bumps across a number of lengths helping secure it in one place and reducing the chances of the speed bump moving or twisting under the stress of vehicles passing over it. This tube is made from galvanised steel making it super durable and less susceptible to rusting than non galvanised steel. It has a diameter of 48mm and length of 1200mm meaning a single tube will span across multiple sections of SiteCop acting as an additional security measure and reducing the chances of it moving or twisting under the stress of vehicles passing over it.
