Mitered Drain - 6" Mitered Drain HDPE Gray 3:1 Slope

The 6" Mitered HDPE Drain offers an angled, low-profile solution for challenging drainage areas where minimal grade difference exists. Ideal for use in culverts, bioswales, under sidewalks, or hard-to-drain landscapes, this drain allows water to flow directly in or out of piping, promoting efficient runoff control and reducing standing water. Compatible with most pipe types and designed for fast installation, it’s a reliable alternative to pop-up emitters and dry wells.

Key Features:

• Directs water to the flow line for enhanced drainage in flat areas
• Usable as either an inlet or outlet with universal pipe compatibility
• Sloped grate design prevents drop typical in standard inlets
• Minimizes standing water to reduce mosquito concerns and promote soil absorption
• UV-inhibited HDPE grate withstands sun exposure and resists degradation
• 3:1 slope with 41.9 sq. in. of open grate area for improved flow
• Easy installation—no cutting, gluing, or concrete curing required
• Prevents rodent access to drain pipes and crawl spaces
