ACO KlassikDrain Type 490Q Slotted Stainless Steel Grate - 1 Meter

Product Details: ACO KlassikDrain Type 490Q Slotted Stainless Steel Grate - 1 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 490Q pairs that stainless finish with heavy-duty capability: a 39.37" (1 m) slotted grate in 16 gauge Grade 304 stainless steel, with slots of 1.75" x 0.38" and 1.17" x 0.38" and 17.6 sq in of intake area per half meter. Rated EN 1433 Load Class E - 134,885 lbs (1,856-2,785 psi per the spec sheet) - it stands at the top of the stainless range, suited to the most demanding commercial and industrial drainage environments, and it carries Bicycle Safe, Anti-Slip, and LEED designations. The patented QuickLok boltless locking system holds it securely in service: the grate stud push-fits into the stainless spring clip of a QuickLok locking bar, sold separately (channel bar 02899; Series 900 catch basin bar 98717).

Quick Look

• Part Number: 31650
• Type 490Q slotted grate design - slots 1.75" x 0.38" and 1.17" x 0.38"
• Dimensions: 39.37" (1000 mm) Length x 4.84" (123 mm) Width
• Material: 16 gauge Grade 304 stainless steel
• Load Recommendation: EN 1433 Load Class E - 134,885 lbs (1,856-2,785 psi per the spec sheet)
• Intake area: 17.6 sq in per half meter of grate
• Weight: 13.4 lbs
• Bicycle Safe, Anti-Slip, and LEED
• Locking: patented QuickLok boltless system - the grate stud push-fits into the stainless spring clip of a QuickLok locking bar, sold separately (channel bar 02899; Series 900 catch basin bar 98717)
• Pallet quantity: 200
• Material: 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: Type "D" grates use the DrainLok barless system (no locking bar needed); Type "Q" grates use the QuickLok system with a locking bar, sold separately (part 02899 for channels)
• Load Recommendation: each grate carries its own EN 1433 rating - Class A through Class E across the stainless range - and the grate fitted determines the realized load class of the installed channel system
• Available in perforated, slotted, longitudinal (wedgewire), and mesh designs, in 39.37" (1 m) and 19.69" (0.5 m) lengths
• ADA-compliant, heel-resistant grate options available within the range
• Used for capturing and redirecting excess stormwater to safe locations
• Removing the grates (and QuickLok bar, where used) leaves uninterrupted access to the trench for maintenance
