Determining your Grate Size

How to measure for your drainage grate

Determining what replacement grate you need can be a challenging prospect. There are many different manufacturers of trench drain and catch basin grates and each one makes their grates to fit their own drainage channel or basin. A 3 inch grate from one manufacturer will probably not fit a 3 inch channel from another manufacturer.

Many folks think they have NDS Mini Channel when it could easily be Oldcastle or Carson – or vice-versa.  These grates are not interchangeable.

 

For a trench system grate replacement quote, we’ll need:

  • Exact width of the trench or channel
  • Shoulder height
  • Channel width
  • Length of the channel run
  • What will be driving over the grates
  • Zip Code of where grates will be shipped

The easiest way is to take several photos of your drain and existing grates and email them to us at sales@drainagekits.com. Our experienced staff will determine what system you have installed. We can then recommend replacement options like polyolefin slotted or steel grates.  We also carry a wide assortment of decorative cast iron grates to fit your existing channel or catch basin.
