Mitered Drain™ is perfect for use in hard to drain areas where lack of grade difference is a problem. Because of its sloped grate, water flows directly into the pipe eliminating the drop typical in conventional inlets allowing for better drainage in flat areas that need extra slope to achieve proper drainage.  

For use with culverts, under sidewalks, in planter areas, creeks and swales or any difficult-to-drain location.

• 3:1 Slope  
• HDPE grates have UV inhibitor
• Area of grate opening (165.1 sq. in.)
• Set screws are type 300 stainless steel
• Not recommended for traffic loads
• Made in USA
• Non-cancellable and non-returnable

Allows water to be diverted and released to water-safe areas away from structures, erosion-prone landscapes and poor drainage areas.

Permits water captured by grates, catch basins, channel drains, Flo-Well, downspouts and roof gutter systems to flow through the drainage pipe and away from structural foundations to safe or useful areas. For example, water can be routed from a low area next to a foundation to a water safe area such as a curbside drainage system.

Opened by the hydrostatic pressure of water flowing through the drain pipe. As flow diminishes the Emitter closes again. The special patented design allows the Emitter to open with a negligible amount of pressure. Since the Emitter is closed during dry weather, debris and rodents cannot enter the drain pipes.

Features

• OVERALL TOP WIDTH 5 15/16"
• Polyolefin Pop-Up Drainage Emitter with spring loaded center and UV inhibitor
• Spring automatically retracts
• PVC 90 degree elbow with drain hole or slot and HDPE Adapter #3PExDS
• 40 G.P.M.
• Fits 3" Corrugated Pipe
• Can be installed in vertical applications - ideal for discharging water from retaining walls and street curbs
• May be used with Flo-Well to relieve overflow

Mitered Drain™ is perfect for use in hard to drain areas where lack of grade difference is a problem. Because of its sloped grate, water flows directly into the pipe eliminating the drop typical in conventional inlets allowing for better drainage in flat areas that need extra slope to achieve proper drainage.  

For use with culverts, under sidewalks, in planter areas, creeks and swales or any difficult-to-drain location.

• Light Duty retail / consumer model
• DIFFERENT DISCHARGE DESIGN THAN THE CONTRACTOR GRADE GRAY AND BLACK MODELS
• 3:1 Slope  
• HDPE grates have UV inhibitor
• Area of grate opening (9.85 sq. in.)
• Set screws are type 300 stainless steel
• Not recommended for traffic loads
• Made in USA

Architectural grade, structural retaining wall drain components are designed to hide exposed drain pipes in large and small, residential and commercial retaining walls while providing optimum egress of water flow (weeping).

Wall Drains can also be used on barbecue islands, outdoor kitchens, fire pits and other applications to complete a pleasing, continuous wall face without the unsightly interruptions of intermittent drains or air vents.

• Durable laser-cut stainless steel with powder coated faux finish inspired by colors in natural stone.
• Built-in anchor points and locking tabs for fast installation.
• Available in 7 colors
• Available in 4 sizes: 3" x 3" for 3" blocks, 4" x 4" for 4" blocks, 5" x 5" for 7" & 8" tall blocks and 6' x 6" for 6" blocks.
• Made in USA
• Not to be used with roof drains as solids may cause clogging.

INSTALLATION INSTRUCTIONS:

Bend side tabs outward and fit to lock against neighboring wall blocks. Optional: Run a bead of adhesive across the holes on the top and bottom flange. Place drain into wall geometry same as an actual block on first course at ground level. Place drainpipe or aggregate against back of drain, filling all voids. Not to be used with roof drains as solids may cause clogging.
