How to select KERDI-Line Channel Body/Grate Size
Because KERDI-Line channel bodies are made out of stainless steel, they cannot be cut (nor extended). Thus it is important to understand how to select and maximize the correct length of drain and grate combination for your respective project.
CHANNEL BODY SELECTION
There are two columns in the price book associated with selecting a channel body. The first column (L) references the length of the drain grate, or the inside to the inside of the channel body. The second column (L1) references the outside flange to the outside flange measurement.
Use L1.
EXAMPLE: I would like a line drain along the wet wall (plumbing wall) of my shower. From wall to wall (substrate to substrate…not stud to stud), the length is 48”. From column 2 (L1), 49 1/4” is too big, so I would choose 45 5/16”. The item number to the right is KL1V 60 E 110.
GRATE SELECTION
Once the item number has been identified for the channel body, select a grate with the same ending number combination as the channel body. Referencing our example, we need a KL1V 60 E 110 channel body, so we would order a grate of our choice whose item number also ends in 110.
