ACO Drain 94669 K1-621S Catch Basin Top Section (stainless rail, Series 600)

Product Details: ACO Drain 94669 K1-621S Catch Basin Top Section (stainless rail, Series 600)

A complete ACO KlassikDrain installation is more than channel and grate. The K100 (galvanized edge rail) and KS100 (stainless steel edge rail) systems are modular polymer concrete trench drains with a 4" (100 mm) internal width, engineered for commercial and industrial stormwater duty — and ACO backs the line with a full range of factory accessories that make each run easier to install, maintain, and keep in service. From trash buckets, bases, top sections, and risers for the Type 900 in-line and Series 600 catch basins, to locking bars, debris strainers, outlet adapters, installation devices, and Brickslot access spares, every accessory is a genuine ACO Drain part with its own ACO part number, made to fit its matching KlassikDrain component exactly. Selecting the correct part keeps the system performing the way ACO designed it — with grates that release for uninterrupted access to the trench for maintenance.

ACO catch basin top section 94669 is molded from polymer concrete with a cast-in Grade 304 stainless steel frame. The same spare top serves K1-621S, K1-622S, K1-631S, and K1-632S Series 600 basins. It has a 14.17" (360 mm) clear opening and fits the 12 in wide Series 600 body. Confirm the basin series before ordering.
