ACO KlassikDrain K1-621S Series 600 Catch Basin - Stainless Rail, Plastic Base

Product Details: ACO KlassikDrain K1-621S Series 600 Catch Basin - Stainless Rail, Plastic Base

Every ACO KlassikDrain trench run needs a place to collect, filter, and discharge the stormwater it captures, and the K100/KS100 catch basin range is engineered for exactly that job. Each basin combines a polymer concrete top section — frost-proof, salt-proof, and resistant to dilute acids and alkalis, with a steel frame cast in at the factory — with a matching base and a removable polypropylene trash bucket that traps sediment and debris before they reach the outlet pipe. The bucket lifts out for routine cleaning, and the included blanking end kit closes off the unused end of the basin. Rated to EN 1433 Load Class E, these basins are built for the same demanding environments as the channel line — industrial areas, gas stations, and light commercial forklift traffic — and integrate directly into new or existing K100/KS100 runs.

The K1-621S combines a polymer concrete top with a Grade 304 stainless steel frame and a LLDPE plastic base. Its overall dimensions are 22.67" long by 15.91" wide by 29.11" deep, with 24.9 gal capacity and 55.8 lbs published weight. Uses 0.5 m K300 (12") grates and the removable Series 600 QuickLok bar 94564. The complete kit includes the top, base, removable QuickLok bar, blanking end kit, polypropylene trash bucket, and requires a grate selected separately.
