ACO KlassikDrain KS1-10 Sloped Trench Drain Channel with Bottom Knockout - 1 Meter

Product Details: ACO KlassikDrain KS1-10 Sloped Trench Drain Channel with Bottom Knockout - 1 Meter

The ACO KlassikDrain KS100 is the stainless-rail member of ACO's 4" KlassikDrain trench drain line: a modular polyester polymer concrete channel with a Grade 304 stainless steel edge rail integrally cast into each section, typically specified where increased aesthetics or corrosion resistance is required. This sloped channel section carries a 0.5% built-in fall — about 1/17" per linear foot — so a numbered run of one-meter sections builds up to 131'-3" (40 m) of continuous slope without stepping the trench itself. The channel body shares its dimensions and accessories with the galvanized K100: a 4" (100 mm) internal clear width, 5.12" (130 mm) overall width, and the same shared K100/KS100 grate range secured with QuickLok boltless locking. Fitted with the appropriate grate, the system handles loads up to EN 1433 Load Class E — service that spans industrial areas, gas stations, and light commercial forklift traffic.

The KS1-10 is section 10 of the numbered sloped run — ACO part number 74410, weighing 35.3 lbs — with the invert stepping from 5.71" (145 mm) at the inlet (female) end to 5.91" (150 mm) at the outlet (male) end and an overall body depth of 6.50"-6.69" (165-170 mm). Like every fifth section in the run, it carries the bottom knockout: a 4" round / 6" oval opening that allows a bottom-outlet configuration, pairing with debris strainer part 93488 and the 4" oval to 6" round outlet adapter part 95140. Its outlet-end invert also matches the neutral (constant-depth) channels KS1-010 (1 m) and KS1-0103 (0.5 m), which extend the run at this depth.

Quick Look

• Material: High-strength polyester polymer concrete channel body
• Rail Material: Grade 304 Stainless Steel Edge Rail, integrally cast in, at least 3/32" (2.5 mm) thick
• The stainless edge rail is typically specified where increased aesthetics or corrosion resistance is required — the only difference versus the galvanized K100
• 0.5% built-in slope with a 1/17" fall per linear foot — up to 131'-3" (40 m) of continuous slope across the numbered run; neutral (constant-depth) channels can be inserted to extend runs
• Internal Width: 4" (100 mm) nominal clear opening; Overall Width: 5.12" (130 mm)
• Channel Length: 39.37" (1 m)
• Wall thickness at least 0.50" (13 mm), with a partial-radius trench bottom and male-to-female interconnecting end profile
• Horizontal cast-in anchoring keys on the outside wall bond the channel to the surrounding bedding and pavement
• Load Recommendation: up to EN 1433 Load Class E (134,885 lbs / 2,785 PSI) — a system rating; the realized load class depends on the grate fitted
• Polymer concrete properties: 14,000 PSI compressive strength, 4,000 PSI flexural strength, 0.07% water absorption; frost proof, salt proof, and resistant to dilute acids and alkalis
• Connection to Grating: QuickLok boltless locking (K1-QuickLok locking bar, part 02899); DrainLok grates require no bar — grates are shared across K100/KS100, so one grate part number fits either edge rail
• Bottom knockout on this section: 4" round / 6" oval (provided on every 5th channel section in the sloped run) — pairs with debris strainer part 93488 and the 4" oval to 6" round outlet adapter part 95140
• Channels are numbered on the sidewalls and base with cast-on direction arrows, and each end indicates the number of the mating channel
• The sloped range steps from a 3.94" (100 mm) invert at section 1 to 11.81" (300 mm) at section 40
• Manufactured to EN 1433 standards; guide specification also references ASME A112.6.3, Floor and Trench Drains
• Catalog Code: KS1-10 — ACO Part Number 74410 (some ACO literature prints the shared code K1-10 for both edge rails; the part number is the reliable key — stainless part numbers run galvanized + 400)
• Section 10 of the 40-section numbered sloped run
• Invert Depth: inlet (female) 5.71" (145 mm) → outlet (male) 5.91" (150 mm)
• Overall Body Depth: 6.50"-6.69" (165-170 mm)
• Weight: 35.3 lbs
• Matches the invert of the neutral (constant-depth) channels KS1-010 (1 m) and KS1-0103 (0.5 m), which extend the run at this depth
