The best just got better. You asked for it and now we have it. Polylok is proud to introduce our 1 foot tall by 24" riser. It has the same high quality as our 6" tall by 24" risers, but with fewer screws that you and your customers have to put together. Structural ribs inside prevent frost from adhering to the riser in frost prone areas. Made of High Density Polyethylene which won't shatter like some Polypropylene risers. Accepts 2", 3", 4" and corrugated pipe.
