NDS offers a line of channel drain systems called the “Pro Series”. These channels are injected, molded from polyvinyl chloride, and have a neutral slope (no slope). They come in a variety of widths (3”, 5”, 8” and 12”). According to NDS literature asterisk notes, this product is technology licensed from the Italian trench drain manufacturer First Corp.
This product line really has many options if you don’t want pre-sloped channels. From a manufacturing point of view, it makes sense. NDS production facilities would need to stock a bunch of injection mold dies of varying depth in order to make pre-sloped channel systems Injection mold dies are expensive!
With the Pro Series, NDS instead opted to make four channel widths to account for different flow situations. Three of the widest products have two depths (shallow and deep channels). So, in effect, there are seven different channel options in the Pro Series.
The photo above shows three of the four width options (I didn’t show the 12” wide option). The 3” and 5” wide channels come in 40-inch lengths (1 meter). The 8” and 12” wide channels come in 20-inch lengths (1/2 meter).
Pro Series Channels Mean a Flexible Layout
A key feature of the Pro Series trench drain product line is the ability to cut the channels to any desired size. The channels come with a “double ridged” cut line every four inches (4”) along the length of the channel. This makes it possible to trim, for instance, 8 or 12 inches from the channel in order to custom fit the drain into a tight area.
Trim the channel using a simple hand saw. By making your cut in the slot formed by the double ridges, you can easily change the length of the drain while retaining an edge that allows all the standard hardware (end caps and other channels) to be attached. There is no patching of the channel in a custom length situation.
While you can cut a channel to a specific length, specialty channels are available for making 45 and 90 degree bends in the drain. Side outlets are available in 5” and 8” wide channels. Another notable feature is that every channel has a bottom knockout. This gives you flexibility when it comes time to place a bottom discharge. You can place the bottom outlet wherever you want.
Pro Series Grates: Know Your Options
Grating options are not extensive with this brand and vary by channel size. For instance, the 3” wide Pro Series channel only has a gray plastic grate suitable for pedestrian or light vehicle traffic. This may be adequate for homeowners that are looking for a budget driveway drain.
The 5” wide Pro Series drain, however, has the most grating options. Plastic slotted grates (class B loading) are available in six (6) colors. The perforated plastic grating is available, but only in gray. A cast iron grate and a high impact-resistant plastic slotted grate are also available in 5” width.
The 8” and 12” wide Pro Series products have fewer grating options. With the 8” wide channels, you have a choice of three plastic grates, one of which is perforated, and one slotted cast iron grate. The 12” wide channel only has a plastic slotted grate (light vehicle traffic) and a cast iron grate for heavy traffic. All grates, no matter the width, come in 20-inch lengths.
One thing I like about the Pro Series product line over other NDS brands (such as the Mini or Spee-D series) is that it offers more durability and life to your drain system because of the grate to channel width relationship. I feel it is important to have your grate wider than the channel of the trench. This is particularly important in plastic trench drain products. If the grate is wider than the channel, then the concrete that surrounds the trench will be giving added strength to the channel. Systems that don’t have this added support have to rely solely on the strength of the plastic channel. In this latter case, if the ledge that supports the grate breaks, the load capabilities of the grate fail. More on this when I cover other NDS channel drains.
List prices of the NDS Pro Series cover a broad spectrum. The least expensive is, of course, the 3” wide system and prices go up as do the channel widths. Grates with higher load capabilities also come at a premium.
