Product Overview

Froet 100C No Hub Cast Iron Dual Outlet Drain w/ CI Dome

NOTE: Froet is now owned by Zurn.

The Froet Drain® 100C bi-functional roof drain has two independent systems, with two inlets and two outlets. It can be used in any flat roof construction.

All parts are cast iron, not including the steel overflow riser pipe. Connections are all no hub.

  • Standard roof drain supplied with 5-in. high primary strainer and 6-in. high overflow.
  • Low profile roof drain with 3-in. high primary strainer and 4-in. high overflow 

Project Options:

  • Low profile
  • Overflow strainer
  • Deck clamp
  • Drain pan
  • Deck mounting plate
  • Vandal secure strainer

Note: Overflow strainer (OFS) is not included with base drain. The OFS designation must be in part number to include overflow strainer. The vandal secure strainer is standard with the OFS, but optional when not using the OFS.

Installation Tips:

The extensions are to be used to provide clearance of the primary outlet when used with thicker decks and/or thicker insulations.

Froet Industries recommends creating a sump with the insulation to promote flow and prevent ponding due to the height of the drain ring. Ponding at the roof drain can cause debris obstructions in the drain strainer.

The roofing contractor needs to install roofing membrane so as not to obstruct the primary sump area.
