The LevelBest Drainage System ensures a clean, professional installation every time. The system's unique design allows for adjusting height both before and after the concrete is poured, with no chipping or chiseling necessary. Features of the LevelBest Drainage System include a domed top for protection during the concrete pour and heavy duty nickel bronze trim. The system is primer tapped and can be used with tile rings. Cleanouts include a countersunk test plug. Available in 3" x 4" and 4" sizes, configuring the right drainage system for the job is quick and easy. Simply choose the rough-in and trim style or select from pre-configured complete system options to have everything packaged together neatly in one box.
