The POLYCAST® Catch Basin is an important part of a pre-sloped drainage system. This catch basin is manufactured with a high-strength, corrosion-resistant polymer concrete material. It is designed to be used as a collection point and drain run transitions to collect solid debris. The DP0650 can be used as an individual catch basin, or with the POLYCAST® 6″ wide trench drain system. It can also be used beneath the TDS-POLYCAST® TP0650S short catch basin for a deeper installation with a larger capacity.

The catch basin accepts the same grate options, edging, and frames as the POLYCAST® 600 trench drains for an unnoticeable transition between the channels and catch basin. Cut-outs for side, bottom, and end outlets are located on the catch basin for easy installation. A core drill is available before shipment (at an additional cost).

Actual Basin Dimensions: 6-1/4″W x 24″L x 24″H

The following POLYCAST® channels correspond with the catch basin: 600N, 605, 610, 615, 620, 625, and their corresponding halves and neutrals.
