Stegmeier Frontier Deck Drain is a removable top drain that features a double wall base and a snap-in top. When installing this drain, the tops are staggered past the joints making the joints very rigid. The removable top caps make it easy to clean the drain or replace the top caps. It is recommended that you drill and pin the base with a non-Corrosive dowel at 3-foot intervals to stabilize against any movement of the concrete slab. Stegmeier offers a fiberglass Drain Dowel for this purpose. The Down Adapter, Side Adapter, and End Adapter all adapt to 1 1/2″ schedule 40 pipes. Don't see what you're looking for? Send us a message.
