1010 and 102015.25" Diameter Body Roof Drain and Low Profile Dome

Requires Less Manpower, Safer Install from Top of Roof Deck

Installed entirely from above deck on flat roofs of any construction, our labor-saving roof drain simplifies installation, saving steps and the need for a second technician. This 15-1/4" (390) Duco coated cast iron drain will quickly clear large runoff accumulations. The combined flashing clamp and gravel stop protects drain lines from debris and securely grips flashing and roofing materials without puncturing for a leak proof installation. The drain is protected by a low profile, polyethylene dome strainer.

Pro Tip: Time, budget, and safety are important considerations in every job. Smith’s Roof Drain and Overflow Drain with Deck Plate can help with all three.

The drain eliminates the need for underdeck clamps and is mounted directly to the top deck, so it can be installed by a single person. Because you no longer need a second installer on the floor below, you remove potential safety hazards associated with climbing and save on installation time.

Saving time and labor leads to monetary savings that will help your budget.

  • Speed of installation. Roof drains can be pre-assembled to deck plate and placed as one unit from the top roof surface, saving time.
  • Secure Installation. Large Roof Deck Plate is easy to install using fasteners from the top of roof only. No underdeck clamp required means less hardware and time savings.
  • Installation from above means less time on ladders or lifts and less overhead work. The only task after installation is the actual pipe connection, made to a secured assembly.
  • Reliability. The drains are installed in a recess to prevent a water dam.
  • Simplicity. Roof penetrations are square, not round, saving time.

Top Mount, Adjustable, Eliminates the Underdeck Clamp,Eliminates Leaks Associated with Gaskets

Pro Tip: Eliminate any risk of leakage at your gasket seals by taking those seals out of the equation. This top mounted drain elevator, as the name suggests, lifts the drain out of the waterway. The only seal requiredis where the roof waterproofing material is flashed into the drain.

  • Elevates Figure Numbers 1005, 1010, 1070 and 1080 type roof drains
  • Adjustable to compensate for insulation thickness
  • Top adjustment at deck for an easier and more secure installation
  • Overall adjustment height of 6-3/4”
  • Drain Elevator is outside of the waterway, eliminating leaks
  • The cast thread design provides for a quick adjustment - up or down; full adjustment achieved with one full turn
  • Top mount reversible collar eliminates the need for a conventional extension, underdeck clamp and sump receiver
