Introducing LSP Roof Drain Pan "Standard Version"

What is meant by LSP Roof Drain Pan "standard version"?

Roof Drain Pan LSP standard version means that the sump pan is designed to accept a 15″ bottom outlet roof drain only.  This is opposed to the modified version which accepts the side outlet roof drain. 

Both roof drain pans accept the roof drains in 2″ to 8″ pipe sizes without any modifications to the pan or drain. Both are available in no hub and threaded outlet configurations.
