Like the 3" and 8" Pro Series, the 12" Pro Series Trench drains only come in linear pieces. Capable of holding as much water as a 12" piece of pipe, the 12" Pro Series is for those who need to evacuate a massive amount of water in a short period of time. Like most of the other Pro Series Channels, the 12" Pro Series Channels are capable of supporting up to Class D loads. The NDS 12" Pro Series drainage system is easy to install and features a robust design that can withstand heavy rainfall and other harsh weather conditions. This system is ideal for use in residential, commercial, and industrial settings and is an effective way to protect your property from water damage. Don't see what you're looking for?
