Be very careful when tightening the nut, Make sure its level and even pressure is applied.
I ripped the nubs off mine on my first try and i used locktite so it started to dry by the time i could cut new nubs.
As for a handle i just drilled a hole threw the side so i could stick a long screw driver threw the handle and turn it.
Also for me for some reason i had to grind in inside diameter a bit to get the wrench started over the nut. Possibly my pvc was warped or something, But just mentioning it if anyone has issues getting the pipe over the nut.
