The Marathon PROLINER
The standard by which all retrofit roof drains are measured.
- Only drain in the industry that provides multiple seals for water back-up prevention
- Eliminates costly drain removal and searching for matching replacement parts
- Constructed of maintenance free, durable copper and malleable alloy
- Prevents water beck-up leaks and consequential building and roof damage
- Only retrofit drain to fit non-standard sized outlets
- Lowers job costs and helps maintain easier project control
- Installation does not disturb original roof assembly or interior finish of building
- Installed from the roof top by the roofer
- Offers variable lengths of outlets for special applications
Typical Straight Style with Clamping Ring
Malleable metal outlet is designed so that it can be expanded with the Proliner Tool to create mechanical metal-to-metal watertight seals of the new drain in the existing pipe.
