Drain guard and inlet sizing

Measure the grate, say what has to be caught, and see which stocked UltraTech units fit it, exact sizes first. Sizes come from the product listings, so the list is always current.

2Measure it

Measure the grate itself, edge to edge. Under-grate guards hang from the grate, so they need to match it, not the frame or the basin.

What fits

Under-grate drain guard

    Fit is judged on the grate size you enter against the sizes in each product title. Grate frames, basin depth and local permit conditions (NPDES, MS4) can change the choice. A specialist will confirm the model before you order.
