Frank Pattern roof drain installation Instructions
The Frank Pattern brand is owned by LSP Products. While they have a diverse line of products, their roof drains are primarily of the light duty variety. They produce the single primary roof drain in the bottom and the side out versions in 2″ – 4″ no-hub outlets sizes.
They also produce a one piece combination roof drain and overflow also in 2″ – 4″ pipe size and a no-hub connection. They are particularly useful on residential and light commercial roof drain installation projects. Compared to some other light duty roof drains, they are very economically priced.
LSP Products/ Frank Pattern does not produce a sump receiver for their roof drains. Roof Drain Pans Company does however, make custom sump pans for both of their roof drain models and will soon have a sump receiver on the market for each.

These roof drain sump pans provide added benefits to the roof drains installation process by:
- lowering the roof drain which will prevent ponding rainwater and the expensive repair costs associated with it.
- Provide a substantial metal surface for the roofing contractor to attach the roof membrane. This is critical in order to prevent leaks.
