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 is likely to increase the frequency of the drain strainer becoming obstructed with debris.

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