ACO KlassikDrain Type 412Q Perforated Galvanized Steel QuickLok Grate - 0.5 Meter

Product Details: ACO KlassikDrain Type 412Q Perforated Galvanized Steel QuickLok Grate - 0.5 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.

Type 412Q, ACO part 98879, is a half-meter perforated QuickLok grate made from 16 gauge galvanized steel. It weighs 3.2 lbs and carries its own EN 1433 Load Class A - 3,372 lbs - 70 psi rating. Perforations 0.25 in (6 mm) diameter. Intake area 14.1 sq in (91.0 sq cm) per half meter of grate (Jan-2026 spec sheet). The grate stud push-fits into the spring clip of the appropriate QuickLok locking bar, which is sold separately.

• For use with ACO Drain K100, KS100, and H100K-8 channels — 100-series grates are shared across edge-rail materials, so one part number serves both galvanized-rail (K100) and stainless-rail (KS100) channels
• Overall Width: 4.84" (123 mm), sized for the 4" (100 mm) internal width KlassikDrain channel
• EN 1433 load rated — the galvanized grate family spans Class A through Class E depending on grate type, and the grate fitted determines the realized load class of the channel system
