NDS 18x18 catch basin w/grey slotted plastic grate

The 1800 Catch Basin series is a big drain made for larger point drain applications.  With an optional two or four outlet openings, the 1800 Basin commands large water flow.  An expandable catch basin and component parts are also available to increase the nesting depth of the drain.  The 18" plastic basin features optional plastic (gray, black, green) grating at light load class or a commercial, delivery truck grade grate made from cast iron.

For a decorative look, Iron Age produces a grate for this catch basin in their 'Interlaken' pattern.
