Mutual Industries 42-90-4 Single Wall 90 Degree Elbow, 4"

Ease of use. Good quality, easy shipping. I live away from any good supply houses so it is great to be able to buy this stuff online. It may be a little more expensive but worth it when you can just order online.

It fits, it was easy to install, it does not slide out.

Water drains.

All I can say is good luck if you need to buy and assemble a drainage system. Your local store will not have all the pts and pcs you need in stock and every store carriesa non compatible system with the other stores. I made this work but it is far from ideal and costs way too much for what it is.

I should have received an unused piece of pipe fitting.

the description was for a 4-inch drain elbow that would fit 4-inch corrugated pipe. even the sticker on the product says 4 inches however it is NOT 4 inches. It does NOT fit my 4-inch corrugated drainpipe. It is much too big. It is clearly a 6-inch elbow.Money and time wasted.
