ACO KlassikDrain Type 452D Slotted Stainless Steel Grate - 0.5 Meter

Product Details: ACO KlassikDrain Type 452D Slotted Stainless Steel Grate - 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 452D (ACO part number 12641) is the 0.5 meter slotted grate of the stainless range, 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 slots measure up to 1.46" x 0.38" and deliver 17.6 square inches of intake area across the half-meter length, and the grate carries Bicycle Safe, Anti-Slip, 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 needed. At just 3.0 lbs, the grate unlocks and lifts out easily whenever the trench needs to be inspected or cleaned.

Quick Look

• Material: 16 Gauge Grade 304 Stainless Steel
• One part number serves both channel rails: KlassikDrain grates are shared between K100 (galvanized edge rail) and KS100 (stainless edge rail) channels
• For use with ACO Drain K100, KS100, and H100K-8 channels — 4" (100 mm) internal width
• Pairs naturally with the KS100 stainless steel edge-rail channel, specified where increased aesthetics or corrosion resistance is required
• Boltless grate locking: the "D" in Type 452D stands for the DrainLok barless system — the factory-fitted device clips into the channel edge rail and its anti-shunt mechanism restricts unwanted grate movement, with no locking bar needed
• ACO Part Number: 12641 (Type 452D)
• Grate Length: 19.69" (500 mm / 0.5 meter)
• Overall Width: 4.84" (123 mm)
• Slot Openings: maximum 1.46" x 0.38"
• Intake Area: 17.6 sq. in. per half meter of grate
• Weight: 3.0 lbs
• Load Rating: EN 1433 Load Class A — 3,372 lbs (46-70 PSI); the grate fitted determines the realized load class of the installed channel system
• Bicycle Safe, Anti-Slip, and LEED rated
• Used for capturing and redirecting excess stormwater to safe locations
• Removing the grates leaves uninterrupted access to the trench for maintenance
