      How To

      • Determine whether you need a 3″ or 4″ outlet variant, and whether you want ProSeal or Tape seal, and which strainer type.
      • Clean the existing drain area and ensure roof deck is clear.
      • Place aluminum gutter drain so flange lies flat on the roof surface with a 12″ outlet aligned with existing pipe.
      • If using ProSeal, compress it using the ProSeal screwdriver tool; if using tape seal, install accordingly.
      • Snap on or bolt the chosen strainer or grate (stainless steel or aluminum).
      • Flash flange as required (PVC/TPO coatings available if specified).
