Portals Plus 67301, 67311, 67321 - Aluminum Scupper Drains

The Portals Plus Aluminum Scupper Drain is designed for side-wall or parapet wall roof installations where drainage must travel through a wall or side of the roof. It features a cast aluminum sump body measuring 6″ tall by 11″ wide, a removable bolted flashing clamp allowing secure termination of the roofing membrane and flashing plies, and a no-hub outlet extension capable of horizontal, vertical or 45° positioning. Available in 2″ (67301), 3″ (67311), and 4″ (67321) sizes.

Key features:

• Cast aluminum sump body (6″ × 11″) for durable structural drainage at parapet walls.
• Removable bolted flashing clamp lets roofing membrane and flashing be securely compressed and sealed at this low point of the roof system.
• Angle grate strainer and no-hub outlet extension (2”,3”,4”) that may be positioned at horizontal, vertical or 45° to adapt to field conditions. 
• Designed specifically to provide leak-free drainage at the difficult roofing/side-wall junction.

• SKUs: 67301 (2″), 67311 (3″), 67321 (4″) 
• Product type: Aluminum Scupper Drain / Parapet Scupper Drain
• Body material: Epoxy‐coated cast aluminum alloy sump body 6″ tall × 11″ wide

Q: What is the difference between SKUs 67301, 67311 and 67321?
A: The numbers refer to the internal outlet size of the scupper drain: 67301 is for 2″ no-hub pipe, 67311 is for 3″, 67321 is for 4″.

Q: Can the outlet of the scupper be directed horizontally or at an angle?
A: Yes — the outlet hub extension is removable and configurable to 0°, 45° or 90° orientation to adapt to wall or side-wall drainage conditions.

Q: Why is a removable flashing clamp important?
A: The removable bolted flashing clamp allows the roofing membrane and flashing plies to be securely compressed beneath the clamp, which helps create a watertight termination at the low side-wall scupper location.

Q: What materials are used for the sump body and why does it matter?
A: The sump body is cast aluminum alloy and epoxy-coated—this provides corrosion resistance and structural durability in exterior wall/roof scupper applications.
