Yes Quickdrain showerline. SWO

def need to up your budget LOL

I may have used the wrong word with "side" outlet. I mean offset to one side. Like this: I can get these 36" for under $100. That's why I don't see why a 48" would be $400+.

sure in time lets see how it holds up to rust.

But that is not a linear dtain it is A linear drain "strainer" as it has no waterproofing flange it is only suitable for clamp rings and weep systems. hence the pricepoint.

Most all mfg of "Quality drains" make offset options, and will make custom at any location outlet.
