Eliminate unsightly cracking, chipping or bowing curbs!

Once concrete curbs start to deteriorate, they end up looking terrible in front of your home or business. Sometimes, the detriment of the visual drainpipe could result in a possibly dangerous situation by developing a tripping or falling hazard, a possible means to injure a pedestrian or playing child or perhaps damage an automobile or car by extending into the roadway. The J Drain Curb Drain by Granger Plastics eliminates the fears of rusting or dangerous steel piping with its rotationally molded produced curb drain.
