Polylok Skinny 4' Trench Drain (Channel & Grate)

Part Number

The new Polylok 4ft. skinny trench / channel drain system offers many of the same features that our 4ft. heavy duty trench / channel drain system does but in a slim, compact design!

The skinny channel and trench drain design isn’t just a great design; it’s engineered with a smooth installation in mind. Each 4’ segment can be joined together, or cut into 1’ increments. The grate is reversible – one side is flat, the other side is convex. All pieces are ADA compliant. Each trench and channel section has anchor spots for rebar (to hold it down when filling around it) and each 1’ section has a drainage port. The drainage ports accept 2” SCH40 pipe All accessories are manufactured in the same color as the trench for seamless installation.
