Commercial water drainage systems allow safe and efficient drainage for grassed areas, gardens, farms, patio areas, pool sides, office buildings, driveways, or factory interiors. The anti-flotation design prevents floating and doesn’t require staking when setting in concrete. Easy & Quick Installation: You can connect these trench drains together for extra length. The interlocking design connects the drains tightly with no potential leak of water. Detachable grate can be manually installed and detached easily, needs no screws or bolts. It also provides a convenient way to clean the drain if it is bunged up. Various Outlet Connections: Each trench drain provides a bottom outlet with multiple sizes(3.1 inch/ 2.2 inch), and a side outlet(2.2 inch/ 5.5 cm). You can choose the size you need. No outlet connector is required because it is already built-in; thus, the pipe can be connected directly. Durability & High Performance: Sturdy HDPE plastic and stainless steel material creates a hard and durable structure. The load capacity is A15. The HDPE plastic provides a smooth interior surface, which allows faster water intake.
