ACO KlassikDrain KS1-040 Neutral Trench Drain Channel - 1 Meter

Product Details: ACO KlassikDrain KS1-040 Neutral Trench Drain Channel - 1 Meter

The ACO KlassikDrain KS100 neutral channel — listed as a "constant depth channel" in ACO's product literature — is the zero-slope member of the KS100 trench drain line. Each section is molded from high-strength polyester polymer concrete with a Grade 304 stainless steel edge rail cast integrally into the rim — the KlassikDrain edge-rail choice where increased aesthetics or corrosion resistance is required, and the only difference versus the galvanized K100 — and it holds the same invert depth from end to end: the female invert equals the male invert, so the channel conveys water without adding fall. Neutral sections are used to extend a KS100 run beyond the 131'-3" (40 m) of continuous slope the sloped series provides, while the half-meter versions let installers fine-tune run length. The family spans five constant invert depths, from 3.94" (100 mm) to 11.81" (300 mm), in 39.37" (1 m) and 19.69" (0.5 m) lengths — all sharing the 4" (100 mm) nominal clear opening and the full range of shared K100/KS100 grates.

The KS1-040 is the deepest neutral channel in the range: a 39.37" (1 m) section with a constant 11.81" (300 mm) invert, a 12.60" (320 mm) overall depth, and a weight of 59.5 lbs (ACO part number 74449). Depth-matched to the 11.81" (300 mm) invert band of the sloped series, it extends the deepest reach of a run without adding fall. It is cast with a bottom knockout for a 4" round or 6" oval outlet connection; at this section depth the bottom outlet discharges 187 GPM (0.42 CFS) through the 4" round outlet or 306 GPM (0.68 CFS) through the 6" oval outlet — pipe flow rates at the outlet, not channel flow rates. Like every KS100 channel, it accepts the full shared range of K100/KS100 grates, making it a dependable deep section for commercial and industrial trench drain runs.

Quick Look

• Neutral (zero-slope) constant-depth channel section: the female invert equals the male invert, extending run lengths beyond the 131'-3" (40 m) the sloped KS100 series provides
• Internal Width: 4" (100 mm) nominal clear opening; Overall Width: 5.12" (130 mm)
• Material: High-Strength Polyester Polymer Concrete — minimum 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
• Rail Material: Grade 304 stainless steel edge rail, integrally cast in by the manufacturer, at least 3/32" (2.5 mm) thick — specified where increased aesthetics or corrosion resistance is required, the only difference versus the galvanized K100
• Wall thickness at least 0.50" (13 mm)
• Partial-radius trench bottom with a male-to-female interconnecting end profile; horizontal cast-in anchoring keys on the outside wall bond the channel to the bedding and pavement
• Bottom knockout for a 4" round or 6" oval outlet connection
• Bottom outlet flow at this section depth: 187 GPM (0.42 CFS) through a 4" round outlet; 306 GPM (0.68 CFS) through a 6" oval outlet (pipe flow rates at the outlet, not channel flow rates)
• Overall channel depth equals the invert depth plus 0.8" (20 mm)
• Connection to Grating: QuickLok® boltless grate locking (K1 QuickLok locking bar, part 02899); DrainLok grates require no locking bar
• Grates are shared across K100 and KS100 — one grate part number fits either edge-rail material
• Load Recommendation: Varies on grate selection (up to EN 1433 Load Class E, 134,885 lbs, 2,785 psi — a system rating that depends on the grate fitted)
• Manufactured to EN 1433 standards; guide specification references ASME A112.6.3, Floor and Trench Drains
• After removal of the grates and QuickLok bar there is uninterrupted access to the trench to aid maintenance
• Channel numbering and direction arrows are cast on the sidewalls and base to simplify installation sequencing
• Depth-matched to the 11.81" (300 mm) invert band of the sloped series — extends the deepest reach of a run without adding fall
• Catalog Code: KS1-040 — ACO Part Number: 74449 (some ACO literature prints the shared K1- code for both edge rails; the part number is the reliable key)
• Dimensions: 39.37" (1 m) Length x 5.12" (130 mm) Overall Width x 12.60" (320 mm) Overall Depth
• Constant Invert Depth: 11.81" (300 mm)
• Weight: 59.5 lbs
• Deepest neutral channel in the KS100 range
