ACO KlassikDrain Type 413D Perforated Galvanized Steel Grate (ADA) - 0.5 Meter

Product Details: ACO KlassikDrain Type 413D Perforated Galvanized Steel Grate (ADA) - 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.

The Type 413D (ACO part number 12657) is the 0.5 meter Class C perforated ADA grate of the family — the half-length companion to the 1 meter Type 411D, sized to cover 19.69" (500 mm) half-meter channel sections and to finish out runs where a full-length grate will not fit. Formed from 16 gauge galvanized steel and rated to EN 1433 Load Class C at 56,202 lbs (774-1,160 PSI), it pairs Class C load capacity with an accessible walking surface for K100, KS100, and H100K-8 runs. Its 0.25" (6 mm) diameter perforations deliver 14.1 square inches of intake area over the half-meter length of the grate, and the pattern is ADA Compliant, Heel-Resistant, Heel-Safe, Bicycle Safe, and LEED rated. The factory-fitted DrainLok locking device clips into the channel edge rail, and its anti-shunt mechanism restricts unwanted grate movement — boltless, barless, and with no locking bar to purchase. At just 5.7 lbs, the grate unlocks and lifts out easily whenever the trench needs to be inspected or cleaned.

Quick Look

• Material: 16 Gauge Galvanized Steel
• 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
• Boltless grate locking: the "D" in Type 413D stands for the DrainLok system — factory-fitted and barless, with no locking bar needed
• Grates lift out after unlocking for uninterrupted access to the trench during maintenance
• Used for capturing and redirecting excess stormwater to safe locations
• ACO Part Number: 12657 (Type 413D)
• Grate Length: 19.69" (500 mm / 0.5 meter)
• Perforations: 0.25" (6 mm) diameter openings
• Intake Area: 14.1 sq. in. per half meter of grate — the full length of this 0.5 meter section
• Weight: 5.7 lbs
• Load Rating: EN 1433 Load Class C — 56,202 lbs (774-1,160 PSI)
• ADA Compliant, Heel-Resistant, and Heel-Safe for pedestrian areas
• Bicycle Safe and LEED rated to support sustainable building credits
• DrainLok anti-shunt mechanism restricts unwanted grate movement once the grate is clipped into the edge rail
