Abstract

A slotted drain having a first channeled half having a first engaging structure and a second channeled half having a second engaging structure mating within the first engaging structure is disclosed. The first channeled half can define a cantilever snap-fit recess and the second channeled half can comprise a cantilever snap-fit protrusion. A slot is formed when the first and second channeled halves are joined. The slot is adapted to receive a liquid variant and the slotted drain is adapted to receive the liquid from the slot into the first and second channeled halves. The slotted drain may optionally include a concrete pass-through port, a rebar clip, bedding feet and/or securement ribs. A method of assembling a slotted drain is also disclosed.
