Hercules-Plus is a line of retrofit roof drains with integrated vortex breaker technology that improves the flow of water from the roof. The flow capacity is up to 2.5 times higher than the original Hercules Drains, so the roof sheds excessive weight much faster.
Available in four sizes with an optional TPO or PVC coated flange for membrane attachment. Strainer domes are made of heavy-duty cast aluminum with a safety yellow powder coat.
