ACO Drain 99900 K1-901G Catch Basin Top Section (galvanized rail)

Product Details: ACO Drain 99900 K1-901G Catch Basin Top Section (galvanized rail)

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 part 99900 is the galvanized-frame spare top for K1-901G and K1-906G in-line basins. It is made from polymer concrete with a cast-in galvanized steel frame and fits the 19.69" x 10.06" (500 x 255 mm) in-line basin footprint. The top has a minimum 0.59" (15 mm) wall thickness, channel-connection drillouts, and guides for male channel ends at depths 10, 20, 30, and 40.
