Yes that should work as long as your corrugated pipe is no smaller than 4" inside diameter (actually 3 and 7/8" might work but would be cutting it close). The end of the invisalflow connector is 2" long. Hope this helps!

Yes, I bought these a couple of years ago and they work great keeping the debris out of the drain system. The crate inside can be removed and cleaned if it gets clogged. Good product!

Can these be painted?

I bought 8 of these for my house and shed and love them. Only regret is they don't come in brown like my gutters. They are totally paintable! You should use exterior paint (to resist UV rays and water) but you could use spray paint and a clear coat spray paint, which is easier than hand painting in my opinion

Not this product. It is for 3x5 downspouts and comes with an adapter for smaller downspouts -- not larger.

The discharge end fits inside a 4 inch drain pipe. Secure the unit to the pipe with self-tapping metal screws. There is no need to seal the junction. The whole idea of this unit is to be open to the air so that debris can be cast aside. A significant amount of water will splash out the grate opening when things are working perfectly. If there is no backup in the lower drain, water will not exit at the junction of this unit and the pipe. If there is a backup, then you will want water to escape where possible.

I've been concerned about keeping my gutters clear of debris as my downspouts are connected to the street underground piping and I don't want those underground pipes to become clogged. I was using the bulb shaped screens and they were effective, but even with very few trees in my yard, they required cleaning 3 or 4 times a year. What I discovered was that the bulb shaped screens would begin to clog, and the gutters would fill with water, backing up and distributing leaf debris the length of the gutters. The leaf debris would then bio-degrade into a compost-like sludge. Upon the next downpour, that sludge would then further clog the bulb shaped screens. Bottom Line: Switching to the InvisaFlow Flex Grate cured these problems. They require very little maintenance, I am not climbing up on the roof multiple times a year, the debris that is discharged is fresh leafy material, and because the gutters are able to flow at volume they are not accumulating the sludge I was dealing with using the bulb shaped screens. - Highly recommended! P.S. I would like to see the manufacturer create some variations on the design, as in some locations the discharge shoot would be too high off the ground (and unattractive). I have cobbled together a couple of solutions to get the discharge shoot closer to the ground or to accommodate a needed offset.

Smart design but needed some help. I used screen material to put over the grate held on by magnets to prevent gravel from shingles into corrigated drains. Works great!

Thus far, I've been impressed by these downspout filters. They were easy to install and seem very durable. It's disappointing that they don't have other colors available (wanted white but couldn't find them available anywhere). Function-wise, I'm thoroughly impressed.

Reading another review about rain water coming down the gutter downspout and leaking out past the screen grate...I too had same problem during hard rains so I added a sheet metal cover that could be lifted upwards to access the grate area and remove any trash. I could also close the cover to prevent any water being discharged. I've attached two pictures that show the cover. I also installed a lanyard to prevent the plastic grading from accidently falling into the 4" drain system I had installed. The grate sets on a plastic lip and can come loose. The water diverter under the downspout adapter was not my best work. Its kind of hard to cut plastic so I used some caulk and black duct tape to dress it up. As of now I'm waiting for a hard rain for a real test and that may come soon.

good product to help keep both leaves and any critters from entering the rain barrels. Easy on, easy off if you want to remove it for any reason. Good price compared to straight pipe.

Great product to keep underground drain pipe free of leaves. BUT needs a small improvement which I made with a pocket knife. The lower edge of the deflector shoot is held in place with the outside frame. This creates a small dam which does prevent small leaves from fall out. By cutting away most of the lower edge, it allows leaves to fall freely out.

Fabulous for connecting downspouts to underground drain lines
We are SO happy with these. After installing these between each of our downspouts and our underground drain lines, there is no more drain line clogging, which previously caused significant hassle. Great little invention!
