Our take on the KFFKFF Trench Drain, 20.1 x 5.5 x 3.5 in, 6-Pack Linear Drainage Channels, HDPE Channels with Grates & End Caps

The KFFKFF Trench Drain is a six-pack of HDPE linear drainage channels with grates and end caps, each measuring 20.1 x 5.5 x 3.5 in. The deep channel and wide-slot grate are built to move stormwater off driveways and patios, with a rated flow of 57.2 GPM and a load capacity of 3306 lbs once grouted in cement. Sections join with adhesive and screws, and the grates lift out for cleaning. It suits homeowners and light contractors draining a driveway, patio or garage apron; compared with concrete or cast-iron channel drains it is lighter and easier to cut and set, but plastic channels flex more and depend on a solid bedding to carry vehicle loads.

About the KFFKFF Trench Drain, 20.1 x 5.5 x 3.5 in, 6-Pack Linear Drainage Channels, HDPE Channels with Grates & End Caps

This is a set of six linear trench drain channels made of HDPE, with a grate for each channel. It is designed to carry water away from driveways, patios and other outdoor spaces, helping reduce pooling and keep surfaces drier. The channel is deeper, and a wide-opening grate and groove design help capture extra rainwater during heavy downpours.

The channels are designed for both vehicle and pedestrian traffic when installed correctly. To install, join the channel sections together, apply adhesive (not included), and fasten them with screws. The grate lifts out, so leaves, sand and other debris are easy to clear.

Questions and answers

How much water can one channel handle?
The rated maximum flow is 57.2 GPM per channel. That covers heavy downpours on a typical driveway or patio run, but size the number of channels to the area draining into them.
Can it take car traffic?
Yes, up to 3306 lbs (1500 kg) per channel, but only after the channel is set in cement grout. Installed loose or in gravel, it will not carry that load.
What do I need to install it?
Adhesive for joining the sections and screws to fasten them are needed; the adhesive is not included. The channels also need a trench bed, typically concrete, to sit in.
How do I clean it?
The grate lifts out, so you can pull leaves, sand and debris from the channel by hand or with a hose. Do this before the slots clog and flow drops.
Does it come with end caps?
Yes, end caps are included so the ends of a run can be closed off. Plan the layout so the run ends where you want the caps.
Is it better than a concrete channel drain?
It is lighter and easier to cut and handle than concrete or cast iron, and cheaper to ship. Concrete lasts longer under heavy loads, so for a commercial driveway a cast product may be the safer choice.
