Through practical experience, plumbers have learned that installing roof drain piping through curbs can take up to 45 minutes or longer.
Even after the forms are cut and secured in place, it is still possible that they will be stepped on or bumped out of alignment. In severe situations, if the pipes are too far out of alignment or if the curb becomes chipped to the point it will need to be replaced (and it may be colored concrete), a minor task becomes a major one.
Use model numbers TCD414 and TCD422 for 8? curbs only. In place of those two model numbers, use TCD317 and TCD327 for 6? curbs. If no Curb-O-Let is required, the 414 and 422 drainage channel can be used on 6? curbs.
