These scuppers do the TRICK! Now we have no worry water will come in where it’s supposed to go out.These are built very stoutly, high visibility so you can see what’s up.. come with their own hardware h although we always use our own to be sure we know what we’re installing, because putting things in right the first time insures that screws BITE HARD AND STAY.)very nice product, fits a range of sizes, seems they’ve thought of everything., now just be careful to keep them intact!
