ACO KlassikDrain Type 438D Longitudinal Galvanized Steel Grate (ADA) - 1 Meter

Product Details: ACO KlassikDrain Type 438D Longitudinal Galvanized Steel Grate (ADA) - 1 Meter

Galvanized steel grates are the general-purpose grate family for the ACO KlassikDrain K100 and KS100 4" trench drain systems, engineered to capture and convey stormwater across commercial and industrial applications. Grates in the 100 series are shared across both edge-rail materials, so a single part number fits galvanized-rail K100 channels and stainless-rail KS100 channels alike. The galvanized family spans perforated, slotted, longitudinal, and mesh patterns in 1 meter and 0.5 meter lengths, with EN 1433 load ratings that run from Class A pedestrian duty up to Class E heavy industrial duty, and several patterns carry ADA-compliant, heel-resistant ratings. Every grate secures to the channel with ACO's boltless DrainLok or QuickLok locking, and because the grate fitted determines the realized load class of the installed system, grate selection is the key specification decision for any K100/KS100 run.

The Type 438D (ACO part number 132555) is the longitudinal pattern of the galvanized family in a 1 meter (39.37") length. Formed from 16 gauge galvanized steel with 1.15" x 0.3" (29 x 8 mm) longitudinal slots, it provides an intake area of 33.0 sq in (212.90 sq cm) per half meter of grate. It is ADA Compliant, Bicycle Safe, Heel-Resistant, and Anti-Slip rated, supports LEED credits, and carries an EN 1433 Load Class B rating of 28,101 lbs (387-580 psi). The factory-fitted DrainLok boltless, barless locking device clips into the channel edge rail, and its anti-shunt mechanism restricts unwanted grate movement — no locking bar is needed.
