NDS 9-inch Downspout Defender Grate Model 900DSG

Installing catch basins under downspouts is a best practice for managing stormwater and protecting property. Downspout drainage systems move water away from structures where it can do damage. The Downspout Defender makes a drainage system even more effective by capturing more water and deflecting debris to keep the system running clean.

Doesn't fit 2" PVC Sch. 40 Pipe

Tried to install this tee on my existing 2" PVC water service that feeds my house. The tee was suppose to be installed to branch off and feed my detached R.V. Garage. I tried to install the tee on the pipe and couldn't get it closed enough to slide on the clamp. So I decided to use a c-clamp to to squeeze the two halves together and that didn't even get close enough to even get the slide clamp to even start...So I decide to put it together in my hand without installing it on the pipe. When the two haves are together the halves don't make a perfect circle (Round) it's egged shape. Plus with the knurling done on the inside of the halves makes it impossible for the two halves to match up. Not to forget the cog that needs to match up as well...I thought this would be a great idea to NOT shut down the water service and cut in a 2" slip tee. Boy was I wrong....So wasted my time waiting for this tee to show up to make life easier but turn into a NIGHTMARE !!!!! Joe H. (Arizona)
