The Advanced Drainage Systems 4" single wall blind tee connects a lateral drain line to a main drainage line while keeping the branch outlet sealed for future use. The closed end cap can be cut open when ready to add a new tie-in, making this fitting ideal for planned expansions to underground drainage systems.
