Review on Canplas 193066 Countersink 6 Inch White by Michael Olsen

Fits standard 6" Schedule 40 pipe. I just used reverse pliers to get the handles to dig in. Turning was easy, tightening a little less. I could easily use some channel locks as leverage, to twist the pliers to tighten. I don't want to stretch it out too much because I have to put some root killer in it every year. No more running a lawnmower over it. And it looks a lot better than a big white square, that sticking out of the grass.
