The I-shaped clip comprises two wall engaging portions and a two retention portions, and the wall engaging portions of the J-shaped clips each define a substantially planar wall-engaging surface capable of attaching to the wall. The wall-engaging portions of the I-shaped clip each define a substantially planar wall-engaging surface capable of attaching to the wall. The trough portion of the J-shaped clip comprises at least one pliant integral co-extruded seal extending away from a distal edge of the trough portion in an angled configuration, and each retention portion of the I-shaped clip includes at least one pliant integral co-extruded seal extending away from a distal edge of the retention portion in an angled configuration.
