ACO KlassikDrain Type 453D Perforated Stainless Steel Grate (ADA) - 0.5 Meter

Product Details: ACO KlassikDrain Type 453D Perforated Stainless Steel Grate (ADA) - 0.5 Meter

ACO KlassikDrain stainless steel grates bring Grade 304 stainless construction to the K100/KS100 trench drain line — ACO's 4" (100 mm) internal width polymer concrete channel system for commercial and industrial stormwater drainage. Stainless steel is the specification of choice where increased aesthetics or corrosion resistance is required, making these grates the natural companion to KS100 stainless edge-rail channel runs. Every grate in the range shares a single part number across both channel rails, so the same grate drops into K100 galvanized-rail and KS100 stainless-rail sections alike.

The stainless family spans perforated, slotted, longitudinal (wedgewire), and mesh designs in 39.37" (1 m) and 19.69" (0.5 m) lengths, with EN 1433 load ratings from pedestrian-duty Class A to heavy-duty Class E depending on the type selected. Boltless DrainLok or QuickLok locking secures each grate to the channel edge rail, keeping installation fast and leaving uninterrupted access to the trench once the grates are removed for maintenance.

The Type 453D (ACO part number 12665) is the 0.5 meter perforated grate of the stainless family, formed from 16 gauge Grade 304 stainless steel and rated to EN 1433 Load Class A at 3,372 lbs (46-70 PSI) for pedestrian-duty K100, KS100, and H100K-8 runs. Its 0.25" (6.35 mm) diameter perforations deliver 14.1 square inches of intake area per half meter — the full intake area of this 19.69" section — and the ADA-compliant perforated pattern also carries Bicycle Safe, Heel-Resistant, Heel-Safe, and LEED credentials. 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 3.2 lbs, the half-meter grate unlocks and lifts out easily whenever the trench needs to be inspected or cleaned.

Quick Look

• Material: 16 Gauge Grade 304 Stainless 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
• Pairs naturally with the KS100 stainless steel edge-rail channel, specified where increased aesthetics or corrosion resistance is required
• Overall Width: 4.84" (123 mm), sized for the 4" (100 mm) internal width KlassikDrain channel
• EN 1433 load rated — the stainless 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 453D 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: 12665 (Type 453D)
• Grate Length: 19.69" (500 mm / 0.5 meter)
• Perforations: 0.25" (6.35 mm) diameter
• Intake Area: 14.1 sq. in. per half meter of grate
• Weight: 3.2 lbs
• Load Rating: EN 1433 Load Class A — 3,372 lbs (46-70 PSI)
• ADA Compliant, Bicycle Safe, Heel-Resistant, and Heel-Safe
• LEED rated to support sustainable building credits
• DrainLok anti-shunt mechanism restricts unwanted grate movement once the grate is clipped into the edge rail
